391778e09c update: Make ships produce after eating and building
People in sectors first eat, then build the sector, then produce.
People in ships produce, eat, then build.

The starvation command can be off for fishing vessels, because it
doesn't consider the food they produce.

Change ships to match sectors.  "Fixes" starvation.  Fishing boats and
oil derricks being repaired at sea become a bit more productive.

14f3bd9717 update budget: Fix civ counting for happiness and education
Per-civilian happiness and education production is raw production
divided by the number of old-owned civilians.  The update reports the
number of old-owned civilians ("total pop was %d").

This number of civilians is also used by budget to predict cost of
tech when option TECH_POP is enabled, but that doesn't match how the
update computes the cost.  To be fixed next.

Civilians loaded on ships are only counted by the update, not by
budget.  Harmless, as budget doesn't compute happiness and education.
Civilians loaded on land units are ignored by both.  None of the stock
game's land units can load civilians.

Civilians in sectors are counted before plague deaths, and in ships
afterwards.

Fix upd_ship() and upd_land() to count civilians the same way as
prepare_sects() does for sectors.

25a6cf92b2 update: Don't double-round money, fixing mil pay and more
The update tallies income and expenses in full dollars.  Each debit or
credit is rounded before it is added to the tally.  Different things
are rounded differently.  Examples:

* Each sector's military pay is rounded down.  In the stock game, 1m
  is paid $4.999998, so n mil cost n*$5 -$1, for all practical n.  10m
  in one sector cost $49, but spread over ten sectors they cost only
  $40.

* Total pay for military in ships and land units is rounded down.

* Each plane's military pay is rounded down (used to be rounded up
  except for broke countries until recent commit 2eb08f4).  In the
  stock game, flight pay is 5 * $4.999998 = $24.99999.  For a plane
  with n mil, that's n * $25 - $1.  Filed under plane maintenance, not
  military payroll.

* Each sector's civilian tax is rounded.  In the stock game, 1c pays
  $0.499998.  10c in one sector pay $5, but spread over ten sectors
  they pay nothing.

* An occupied sector's civilian tax is first rounded, then divided by
  four and rounded down *boggle*.

* Each sector's uw tax is rounded.  In the stock game, 1u pays
  $0.106662.  1-4u in one sector pay nothing.  5-14u pay $1.

This is madness.  Has always been that way.

Drop the rounding and track money in type double throughout the
update.  Round only the final amount, randomly.  This is similar to
how commands accumulate a money delta in player->dolcost.

Likewise, tally the subtotals for budget in type double.  Display them
rounded to full dollars.

10789a0365 budget: Fix treasury tracking
The update simply updates each nation's nat_money as it goes.  Works.
Except it doesn't update when it runs on behalf of budget.  But it
still checks nat_money to determine whether the nation is solvent.
These checks are all broken.  Leads to massive mispredictions when
you'd go broke or solvent during a real update.

Track money unconditionally in nat_budget[].money.  Delay update of
nat_money until prod_nat().  Replace separate money[] by new
nat_budget[].start_money.  Closes bug#235.

Remaining difference between budget and update in the update test:

* #1: budget mispredicts plane #100 gets built (to be fixed)

* #2: budget shows ship, plane and land unit maintenance when broke,
      but update damages them instead (correct)

* #2: sector -14,0 converts, quadrupling its taxes (correct)

* #4 & #5: bank with dust and bars taken over by che (correct)

* #4: plague deaths (correct)

2eb08f40c7 budget: Track ship, plane, land unit expenses in nat_budget[]
Extend struct budget member bm[] to cover ships, planes and land
units, too.

Plane maintenance changes because pilot pay is now consistently
rounded down.  Before it was rounded down for broke countries, else
up.  The stock game's pilots earn a little less than $25, and solvent
countries save $1 per plane.  The rounding doesn't make much sense
either way.  To be be addressed in a later commit.

ae2ae938b5 update: Saner rounding of unit building money and work
shiprepair() limits the efficiency gain to how much the workers can
build, rounding randomly.  It charges work, money and materials for
the efficiency actually gained, rounding work up, money down, and
materials randomly.  Same for planerepair() and landrepair().  Has
always been that way.

If you get lucky with the random rounding, you may get a bit of extra
work done for free.

The budget command runs the update code, and can be off by one due to
different random rounding.

Sector production used to have the same issue, only more serious,
because a single unit of tech production matters much more for the
budget than a single point of unit efficiency gain.  I fixed it in
commit 6f7c93c, v4.3.31.

Fix it for unit building the same way: limit efficiency gain to the
amount the workers can produce (no rounding).  Work becomes a hard
limit, not subject to random fluctuations.  Randomly round work and
money charged for actual gain, like we do for materials.  On average,
this charges exactly the work and money that's used.

This lets budget predict how much gets built a bit more accurately.
It's still not exact, as the amount of work available for building
remains slightly random, and the build cost is randomly rounded.

The old rounding of work for ships carries the comment "I didn't use
roundavg here, because I want to penalize the player with a large
number of ships."  Likewise for planes.  Rounding work up rather than
randomly increases the work cost by 0.5 per ship, plane or land unit
on average.  I could keep the penalty by adding 0.5 before random
rounding.  Not worth it, since the effect is actually pretty trivial.
Let's examine a fairly extreme case: an airfield with 600 available
work repairing a huge number of lightly damaged planes, say f2 with
81% average efficiency.  The old code lets the airfield repair roughly
600 / 6.5 = ~92 planes, the new code 600 / 6 = 100.

199b1498c8 update: Use a scratch sctstr for unit repair simulation
If player->simulation, shiprepair(), planerepair(), landrepair() must
use the bp map, and must not change game state.

Copy the sector to a scratch buffer, update it from the bp map, work
on the sector normally, then write back to the bp map.  This is
simpler and safer.

Since get_materials() loses its connection to the bp map, move its
declaration out of budg.h.

While there, drop an ancient debugging logerror() from landrepair().

3b543dac8a update/ship: Don't let stopped sectors repair foreign ships
Stopping a sector disables repairs of own ships completely.  Foreign
ships, however, repair just fine, consuming the sector's materials
and, if it's a harbor, its available work.

Disable repair of all ships in stopped sectors.  This is consistent
with plane and land unit repair.

68c7c08a58 config: Make work to build units independently configurable
The work required for build and repairs is traditionally a function of
build materials: 20 + lcm + 2*hcm for ships, planes and land units,
and (lcm + 2*hcm + oil + rad)/5 for nukes.  Make it independently
configurable instead, via new ship-chr, plane-chr, land-chr, nuke-chr
selector bwork, backed by new struct mchrstr member m_bwork, struct
plchrstr member pl_bwork, struct lchrstr member l_bwork, struct
nchrstr member n_bwork.  Keep the required work exactly the same for
now.

Clients that compute work from materials need to be updated.  Easy,
since build work is now exposed in xdump.

dc73207a99 sail: Remove option SAIL
SAIL has issues:

* Sail orders are executed at the update.  Crafty players can use them
  to get around the update window.

* The route is fixed at command time.  You can't let the update find
  the best route, like it does for distribution.

* The info pages documenting it amount to almost 100 non-blank lines
  formatted.  They claim you can follow friendly ships.  This is
  wrong.  They also show incorrect follow syntax.  Unlikely to be the
  only errors.

* Few players use it.  Makes it a nice hidey-hole for bugs.  Here are
  two nice ones:

  - If follow's second argument is negative, the code attempts to
    follow an uninitialized ship.  Could well be a remote hole.

  - If ship #1 follows #2 follows #3 follows #2, the update goes into
    an infinite loop.

* It's more than 500 lines of rather crufty code nobody wants to
  touch.  Thanks to a big effort in Empire 2, it shares some code with
  the navigation command.  It still duplicates other navigation code.
  The sharing complicates fixing the bugs demonstrated by
  navi-march-test.

Reviewing, fixing and testing this mess isn't worth the opportunity
cost.  Remove it instead.  Drop commands follow, mquota, sail and
unsail.  Drop ship selectors mquota, path, follow.

struct shpstr shrinks some more, on my system from 160 to 120 bytes.

48e656c057 autonav: Remove the feature
The autonavigation feature has issues:

* Autonavigation orders are executed at the update.  Crafty players
  can use them to get around the update window.

* Usability is poor:

  - The order command is overly complex, not least because it can do
    five different things: clear, suspend, resume, declare route, set
    cargo levels.

  - Unlike every other command involving movement, order does not let
    you specify routes, only destination sectors.

  - Setting cargo levels can silently swap start and end point of a
    circular route, because "this keeps the load_it() procedure
    happy".  Maybe it does, but it surely keeps players confused.

  - Setting "start" cargo levels actually sets the "end" levels, and
    vice versa.  Has always been broken that way.

  - Predicting what exactly autonavigation will do at the update isn't
    easy.

* The info pages documenting it amount to almost 400 non-blank lines
  formatted.  They claim only merchant ships can be given orders.
  This is wrong.  Unlikely to be the only error.

* Few players use it, and its workings at the update a fairly opaque.
  Makes it a nice hidey-hole for bugs.  Here are two:

  - Unlike the scuttle command, autonavigation happily scuttles trade
    ships while they're on the trading block.

  - Unlike the load command, autonavigation can load in friendly and
    allied sectors.

* It's more than 700 lines of rather crufty code nobody wants to
  touch.  Thanks to a big effort in Empire 2, it shares code with the
  navigation command.  It still duplicates load code.  The sharing
  complicates fixing the bugs demonstrated by navi-march-test.

Reviewing, fixing and testing this mess isn't worth the opportunity
cost.  Remove it instead.  Drop commands order, qorder and sorder.
Drop ship selectors xstart, xend, ystart, yend, cargostart, cargoend,
amtstart, amtend, autonav.

xdump ship sheds almost half its columns.  struct shpstr shrinks, on
my system from 200 to 160 bytes.

8ccad0d779 Units no longer die from lack of maintenance
Damage due to lack of maintenance is now limited by the unit's minimum
efficiency.

Before, units could die.  Unfortunately, the update left any embarked
units on their dead carrier.  Should have seen this when I fixed a
related bug in commit c2c0d1ff, v4.3.22.  Broken for ships and land
units when Empire 2 added their maintenance cost, and for planes when
commit 2e40a4bb (v4.3.4) replaced nuclear stockpiles by nuke units.
The common root cause of these bugs is the update bypassing pre-write
functions (bug#1010856).

If another unit with the same number got built, it picked up the stuck
cargo, triggering the oops from commit 6fb5caf6, which see.

In "stuck on dead carrier" state, units pretty much behave as if their
carrier was still alive, with additional protection from the fact that
a dead carrier can't be damaged or boarded.

The server detects this state on startup since commit 7da9aab5, and
refuses to start.

Only a deity can take units off a dead carrier.

7e2008e7f4 License upgrade to GPL version 3 or later
Why upgrade?  I'm not a lawyer, but here's my take on the differences
to version 2:

* Software patents: better protection against abuse of patents to
  prevent users from exercising the rights under the GPL.  I doubt
  we'll get hit with a patent suit, but it's a good move just on
  general principles.

* License compatibility: compatible with more free licenses, i.e. can
  "steal" more free software for use in Empire.  I don't expect to steal
  much, but it's nice to have the option.

* Definition of "source code": modernization of some details for today's
  networked world, to make it easier to distribute the software.  Not
  really relevant to us now, as we normally distribute full source code.

* Tivoization: this is about putting GPL-licensed software in hardware,
  then make the hardware refuse to run modified software.  "Neat" trick
  to effectively deny its users their rights under the GPL.  Abuse was
  "pioneered" by TiVo (popular digital video recorders).  GPLv3 forbids
  it.  Unlikely to become a problem for us.

* Internationalization: more careful wording, to harden the license
  outside the US.  The lawyers tell us it better be done that way.

* License violations: friendlier way to deal with license violations.
  This has come out of past experience enforcing the GPL.

* Additional permissions: Probably not relevant to us.

Also include myself in the list of principal authors.

Food supply during update adds complexity to the update.  How much
good it does to players is highly doubtful; certainly nobody can rely
on it.  It isn't covered by the starvation command.  Starving ships or
land units can steal enough food from their sector to make it starve,
too.  Finally, the supply code is notoriously hard to use correctly.
We don't know of issues with the update's use, but we haven't
convinced ourselves that there aren't any either.
