4824648978 bridgefall: Fix loss of bridge support with EASY_BRIDGES off
With EASY_BRIDGES off, bridge spans need to be next to a bridge tower
or a bridge head that is at least 20% efficient to remain standing.

When a bridge tower or head gets damaged below 20%, adjacent spans may
lose support.  Bug: they don't fall when they're next to another
bridge head below 20%.

Has always been broken.

292bfac797 bridgefall: Fix support loss with EASY_BRIDGES and BRIDGETOWERS on
With EASY_BRIDGES on, bridge spans need to be next to land or a bridge
tower to remain standing.

Land can't go away, but a bridge tower can fall.  Bridge spans next to
it may lose support then.  Bug: they don't fall when they lose support
that way.  Fix that.

f5244d4702 bridgefall: Fix harmless coordinate normalization bug
bridgefall() wants to do this:

    for all possible pairs of directions (i, j)
        if i and j cancel out
	    continue
	do stuff

It does it by adding direction offsets to start coordinates, and
comparing the resulting coordinates to the start coordinates.  Fine,
except it neglects to normalize the resulting coordinates.

Harmless in practice, because you can get an incorrect result only
when the path goes around the world, which it can do only in a 4x2
world.

Fix it anyway, by testing "directions cancel out" directly.

eeb62ab280 build scrap: Redo 4.2.3's fix for manufacturing military
scrap has always returned the scrapped planes' full crew, regardless
of efficiency.  build, however, charged only 10%.  If you built ten
planes with one crew each, you used up one military.  Or none, if you
abused random rounding.  If you scrapped them again, you got ten back.
Pretty pricey way to manufacture military, but wrong all the same.

4.2.3 plugged this hole by making build never round military to zero.
Ugly special case, and not documented.  Also doesn't prevent abuse of
random rounding for planes requiring more than 10 crew, but such
planes don't exist in the stock game.

Redo this fix:

1. Make scrap return crew proportional to efficiency, randomly
rounded.  Note that scrap returns only two thirds of the other
materials, rounded down.  Recycling materials isn't perfect, but
recycling aircrew is.

2. Drop the special case from build: treat military just like other
materials.

1227d2c931 build: Stop abuse of construction material random rounding
Construction materials required for building a ship, plane or land
unit are rounded randomly.  Crafty players exploit this to save
materials: they put just enough materials there so that build succeeds
when it rounds down.  Then they simply keep trying until it succeeds.

Planes and land units are built at 10%, so rounding happens when
materials for 100% aren't multiples of ten.  If they're below ten, you
can even build without materials.  In the stock game, this is the case
for linf, and many plane types.

Ships are built at 20%, so multiples of five aren't rounded.  Ship
building never rounds in the stock game.

Prevent the abuse of random rounding by requiring the required
fractional amount rounded up to be present.  Don't change the actual
charging of materials; that's still randomly rounded.

a109de948b Remove option TREATIES
TREATIES has issues:

* Treaties can cover attack, assault, paradrop, board, lboard, fire,
  build (s|p|l|n) and enlist, but not bomb, launch, torpedo and
  enlistment centers.

* Usability is very poor.  While a treaty is in effect, every player
  action that violates a treaty condition triggers a prompt like this:

    This action is in contravention of  treaty #0 (with Curmudgeon)
    Do you wish to go ahead anyway? [yn]

  If you decline, the action is not executed.  If you accept, it is.
  In both cases, your decision is reported in the news.

  You cannot get rid of these prompts until the treaty expires.

* Virtually nobody uses them.

* Virtually unused code is buggy code.  There is at least one race
  condition: multifire() reads the firing sector, ship or land unit
  before the treaty prompt, and writes it back after, triggering a
  generation oops.  Any updates made by other threads while trechk()
  waits for input are wiped out, triggering a seqno mismatch oops.

* The treaty prompts could confuse smart clients that aren't prepared
  for them.  WinACE isn't, but is reported to work anyway at least
  common usage.  Ron Koenderink (the WinACE maintainer) suspects there
  could be a few situations where it will fail.

This feature is not earning its keep.  Remove it.  Drop command
treaty, consider treaty, offer treaty, xdump treaty, reject treaties.
Output of accept changed, obviously.

6d2244093a fire: Fix ship retreat when helpless
Two bugs.  First, multifire() checks the condition only for surface
ships, not for submarines.  Second, multifire() neglects to write back
the ship after retreating it.  The player is told the ship retreats,
but it actually stays where it is.

Broken since retreat was added in Chainsaw.  Previous fixes (commit
8065fe8, v4.3.1 and commit de2651e, v4.3.19) "fixed" only the

075704276e fire: Check land unit guns earlier, drop useless checks
We check all necessary conditions for being able to fire before
prompting for a target.  Except for land unit guns.  Clean that up.

fort_fire(), shp_fire() or lnd_fire() fail only when the fort, ship or
land unit can't fire.  If that happens, our checking is incomplete.
Oops then.

We recheck some of the necessary conditions after getting the target.
However, because the command fails when the firing sector, ship or
land unit has changed since the first check, these rechecks can't
fail.  Drop them.

Note that the rechecks were just as useless before commit 66165f3
fixed fire to fail on change, because they rechecked the unchanged
cached copy instead of the possibly changed original.

e852d458f9 tests: New test-suite-only command __cmd
Adding or removing a command to/from a test has unfortunate effects:

* Before the previous commit: if the command consumes pseudorandom
  numbers, all subsequent users of pseudorandom numbers get different
  ones.  This has always been a major headache.

* Since the previous commit: all subsequent users of pseudorandom
  numbers get different ones whether the command consumes any or not.
  That's even worse.

* If the command uses BTUs, subsequent prompts are changed.  Not
  nearly as bad as the above, but still annoying.

Create a new command __cmd to allow compensating for adding/removing
commands for tests.  Throw in the ability to compensate treasury
changes for good measure.  Three arguments: command count, BTU use,
money use.

Usage example: say you add a convert command to a test, and it uses 3
BTUs and $15.  Then you compensate by adding "__cmd added 1 3 15"
right after it.

The command must not be available unless running_test_suite is on, of
course.  Make it require the new player command capability TESTING,
and give that to all players when running_test_suite is on.

The command is intentionally not documented in info.  Switch
running_test_suite off for info-test, to hide it (and any future
TESTING commands) from info-test.

Suppress the command counter increment for TESTING commands, so they
can be used without upsetting pseudorandom numbers

73f1ac8a2c tests: Make robust against variations in PRNG use
Tests need repeatable pseudorandom numbers to yield repeatable
results.  We seed the pseudorandom number generator with a fixed value
(emp_server -R) to make it produce the same sequence of numbers every
time.  But whenever code exercised by a test is changed to consume
fewer or more of them, all subsequent users get different numbers
regardless.  The ensuing test result changes are extremely tedious to
review.

To address this problem, reseed the PRNG with the count of commands
right before executing a command when running_test_suite is on.  This
way, the effect of perturbing the PRN sequence lasts only until the
next command.

Note that the next command could be another player's.  Doesn't matter.

Adding or removing commands now upsets the PRN sequence even for
commands that don't consume PRNs.  The next commit will take care of
that.

Perturbs test results across the board.  Hopefully, that'll happen
much less frequently now.
