85d8e7fcb1 market: Simplify check for dead trades and document how it fails
We fail to delete trades right away when the unit on sale dies.
Instead, we delete trades of the dead whenever we look at the market.
Doesn't work when new builds reuse the IDs of such dead.  If the new
unit's owner differs from the dead one's, we still delete the trade,
and log "Something weird".  If they are the same, the newly built unit
takes the dead one's place on the market.  Has been that way since the
market was added in 4.0.0.

I can't fix this right now, so mark as FIXME, and drop the logerror().
The first of the two trade deletions is now redundant, so drop that,
too.

6bcd72e241 buy set trade: Fix taking lots off the market
To find out whether a lot is in use, some places check for zero
trd_owner, others for negative trd_unitid.  The former is reliable,
the latter is not: set() fails to change trd_unitid when it takes a
lot off the market.  The next trade-related command then runs
check_trade(), which logs "Something weird" and cleans up the mess.
Broken in commit e16e38dfab (v4.2.18).

Replace the unreliable checks by reliable ones.

Clean up set() not to implictly rely on unused lots having negative
trd_unitid.

The trd_unitid = -1 are unnecessary now, so drop them.

3f2e59ab2f load lload unload lunload: Tweak suppression of error messages
These commands suppress some error messages when ships, planes or land
units involved aren't explicitly selected by UID.  Without this, a
command like "unload plane 80 *" would complain about every plane not
on ship#80.

Correct a few issues with this error suppression:

1. We don't suppress the error when we can't load/unload a ship or
land unit because it's on the trading block.  Do suppress it.

2. We suppress the error message when we can't load/unload due to
foreign sector ownership in all but one places.  Fix that place.

3. Messages about explicitly selected planes and land units to load
are still suppressed when the carrier isn't selected explicitly.
Change this to suppress regardless of the carrier.

3. We suppress the error when a carrier has no room.  Don't, because
it's a potentially confusing silent failure.

7c5e6e7f6d load lload: Drop dead "cannot carry land units" checks
load_land_ship() and load_land_land() fail for carriers that can't
carry any land units before prompting for land units to load.  They
then iterate over land units to load, and fail when the carrrier has
no room.  They either report "cannot carry land units" or "doesn't
have room for any more land units" then.  The former cannot happen.
Crept into load_land_ship() in Empire 2, blindly copied to
load_land_land() in 4.0.0.  load_plane_ship() and load_plane_land()
don't have this issue.

Drop the dead code.

Attempting to unload land units from a carrier that can't carry any

607f15a6f6 load unload lload lunload: Fix for areas starting with a digit
load and lload skip foreign ships unless explicitly named, and
suppress some error messages for ships not explicitly named.  Makes
sense, except the check for "explicitly named" is flawed: it checks
whether the argument starts with a digit.  Works as intended for lists
like 1/2/3.  Broken for areas that happen to start with a digit, such
as 0:9,0:5.  Visible in the load-tend test.

Screwed up when the feature was added in Empire 2.

Fix the obvious way: test for NS_LIST instead.  While there, drop the
p && *p guard, because it's always true after snxtitem().

15a43a780a tend: Suppress "not on ship" unless land unit is selected by UID
The quickest way to tend all land units on a ship is to select all
land units with '*'.  However, tend then prints a "not on ship"
message for every land unit not on the tender, as the load-tend test
demonstrates.  Annoying.  Suppress this message unless the land unit
was explictly selected by UID.  Similar to how load and unload
suppress messages, only they get the condition wrong (to be fixed
soon).

A related annoyance remains, also visible in the load-tend test: tend
can still complain "not on ship" many times when tending explicitly
selected land units from multiple ships.

3064731af4 tend: Don't tend land units to multiple target ships
Each land unit is tended to each target ship in turn, and ends up on
the last one that can take it..  The load-tend test demonstrates this
with command "tend land 173 s 150/165":

    spy  infiltrator #320 transferred from sbc  cargo submarine (#173) to cs   cargo ship (#150)
    spy  infiltrator #320 transferred from sbc  cargo submarine (#173) to ls   landing ship (#165)
    spy  infiltrator #321 is not on sbc  cargo submarine (#173)!
    spy  infiltrator #322 transferred from sbc  cargo submarine (#173) to cs   cargo ship (#150)
    spy  infiltrator #322 transferred from sbc  cargo submarine (#173) to ls   landing ship (#165)

Has been that way ever since Empire 2 added tending of land units.

Fix by breaking tend_land()'s loop over all target ships after a
successful transfer.

Notable coverage gaps:

* Effect on land unit fortification

* Effect on mission and retreat orders

* Ships, land units and planes on sale (option MARKET 1)

* Transmission of plague (option NO_PLAGUE 0)

* Land units loading and unloading civilians (need a custom land unit
  type capable of carrying civilians)

* load refusing to load x-light planes (need a custom ship type that
  can carry helo but not x-light)

* load and lload refusing to load land units carrying land units, and
  lload refusing to load land units onto land units that are being
  carried (need a custom non-heavy land unit type that can carry land
  units)

* tend refusing to tend non-light land units to non-supply ships, or
  to supply ships without room (need custom a non-light assault land
  unit type)
