lnd_put() serves two masters: march, which wants it to report
"stopped" and write back struct ulist member mobility to
unit.land.lnd_mobil, and ground combat, which doesn't.
lnd_put() assumes march when actor is non-zero. Correct (but see
commit 8c502d4). Dates back to Empire 2.
Too ugly for my taste. Specialize for each master instead:
lnd_mar_put() for march, and lnd_put() for ground combat.

Commit d94d269 combined them into unit_put(), but that has turned out
not to be useful. Split them again.

... get_dlist(), att_reacting_units().
This loses malloc() error checking in ask_olist() and get_dlist(). No
great loss, because we don't check in so many other places, including
att_reacting_units(). We should use a wrapper that terminates on
error, though. Left for another day.
ask_olist(), get_dlist() and att_reacting_units() zero the struct
ulist with memset(). lnd_insque() doesn't, so these functions need to
zero any members not otherwise initialized explicitly now.

Members x, y, eff, supplied are not "LAND only", they're used only by
ground combat. They're not used by march.
In ground combat, member mobil is not how much the land unit has left,
it's how much it still needs to be charged.

Some callers have to second-guess shp_check_nav() to figure out
whether CN_LANDLOCKED means "too big to fit into the canal" or "can't
go there at all".
Fix that by returning d_navigation. CN_LANDLOCKED becomes either
NAV_CANAL or NAV_NONE, CN_CONSTRUCTION becomes either NAV_02 or
NAV_60, and CN_NAVIGABLE becomes NAVOK.
The CN_NAVIGABLE, ... codes are now unused. Drop them.

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.

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

Print a message, send bulletin to owner. Affects ship key 'W', land

Edit lets deities load units onto remote carriers, resulting in a
carriers having cargo in another sector. Not good. Cargo gets
teleported to its carrier belatedly when the carrier moves.
Better let edit take care of the teleport.
Also tell the deity that he just caused a teleport. Necessary to give
the deity a chance to catch unexpected changes, e.g. a player moving a
plane right before the deity edits it. Watching out for such changes

Systems using GNU libc such as Linux are frequently configured in a
way getaddrinfo(NULL, ...) put the IPv4 wildcard "0.0.0.0" *before*
the IPv6 wildcard "::" in the result. Because of that, listen_addr ""
listens only on all IPv4 addresses. Workaround: listen_addr "::".
Document it in listen_addr's doc string.
OpenBSD refuses to implement IPV6_V6ONLY, in violation of RFC 3493.
RFC 4038 frowningly recognizes this practice. The only way to bind
both IPv4 and IPv4 there is two separate sockets. Requires more
surgery than I can do now.
Since we can't have both IPv6 and IPv6 on OpenBSD with our single
socket, prefer IPv4, but if that doesn't work, do IPv6.
To prefer IPv6 instead, put 'listen_addr "::"' into econfig. Document
that in listen_addr's doc string.
Code dealing with money mixes int and long pretty haphazardly.
Harmless, because practical amounts of money fit into int on any
machine capable of running the server. Clean up anyway.
Code dealing with reserves mixes int and long pretty haphazardly.
Harmless, because practical reserves fit easily on any machine capable

As long as symbol_by_value(), show_capab() and togg() support only
int, flags need to fit into int.
Not a problem in practice, because no machine capable of running
Empire has int narrower than 32 bits, and 32 bits suffice.
Some flags members are long instead of int: struct lchrstr member
l_flags, struct natstr member nat_flags, struct mchrstr member m_flags
are long. Waste of space on machines with long wider than int.
Change them to int.
Rearrange struct lchrstr and struct natstr to avoid holes.
