This reduces the call depth by one, and eliminates a load of a global
variable that always has the value MULTI_PROTO_UDP. It adds a load of
the address of the empty dispatch object. Overall, this should be an
improvement.
Descent tracked hoard orbs by borrowing the player's proximity bomb
slot. Commit 829e95b6f8 moved proximity
bomb tracking to its own slot, but failed to update the player
death/deres logic accordingly. This caused multiple inconsistencies
when a player was killed in hoard mode:
- The killed player saw the orb drop as expected.
- The killed player _also_ kept the orb in inventory after respawn,
because the counter was not reset.
- Other players saw no orb drop.
Fix the inappropriate retention by resetting the orb count in
init_player_stats_new_ship. Fix the inappropriate failure to drop by
adding a new unconditional field to the player death/deres message. In
hoard games, use it to pass the orb count. In other games, ignore it.

Cross-play between development builds from different commits is never
guaranteed. Increase the protocol version number to force everyone to
sync up. Github user D2Lovin reported that mixing users from two
snapshot builds behaved poorly, but went silent when prompted for more
information. This bump will force users to synchronize, which is a good
idea on principle.

A declaration is useful if it declares an external function. A static
inline declaration, if not followed by the definition later in the same
translation unit, will not be useful. Remove such declarations, and
rely on using the definition as a declaration for those files that
actually call partial_range() or similar functions.
gcc-10 warns that the game information text may be truncated, because it
overestimates the maximum possible length of some strings. Handle the
warning by changing the format string to explicitly truncate these
strings at their maximum legal lengths.
This was requested by a user in early 2018. However, the proposed
prototype was susceptible to various forms of desynchronization, and was
unsuitable for merging. No further revisions were proposed, and the
feature languished. This commit enables the guidebot in cooperative
games and addresses the known synchronization problems, as well as some
other bugs that were uncovered during light testing. This is classified
as an experimental feature because it has not been heavily tested in
complicated games.

- Raise the player limit to 8.
- Remove the logic that forces player counts up/down when switching
between cooperative and deathmatch game modes.
- Add heuristics to add start positions for the extra players, since
standard maps will not have the required number of starts.
The new tracker automatically exposes LAN games to the Internet. This
surprised one user rather badly, prompting him to think he had been
hacked. Add a first-host warning explaining the feature and asking the
user to choose whether to enable NAT hole punch.

digi_play_sample_once is supposed to cancel prior instances of the
sound, but that functionality was lost in
21082c6db2. As a result, the sound can be
stacked up to the limit of the engine. Even when the functionality
existed, its implementation was wrong.
- Change these sounds to be attached to the player generating them.
- Pass the cancellation flag to other players when sending a sound.
- Send the full value of `volume`, rather than truncating it.
- Implement cancellation by killing and restarting the earlier version of a cancelled sound.
- Delete an ugly hack that prevented the patched logic from ever running.
- Fix an ancient quirk in digi_mixer that caused it to report all sounds as not playing, which then caused digi_sync_sounds to instantly cancel the new sound.

Commit f4b21088a0 ("Track vulcan ammo explicitly") fixed an original
retail bug that prevented the thief from stealing energy weapons,
because the thief could only steal weapons for which the player had ammo
and energy weapons never have ammo. This went unremarked for several
years, until a recent report of the new semantics as a game-breaking
regression because the thief is now "ridiculously potent".
Address this report, as well as an intermittently raised issue from
various users over time, by adding two new knobs to both the single
player "Gameplay" menu and the multiplayer setup screen: "Remove Thief
at level start" and "Prevent Thief Stealing Energy Weapons".
"Remove Thief" deletes the thief object during level load. It has no
impact on save games, and changing it after entering a level has no
effect on any thief already in the level.
"Prevent Thief Stealing" is checked at the moment of theft and, when
enabled, prevents stealing primary weapons other than Vulcan/Gauss.
This can be changed at will in single player and is immediately
effective. In multiplayer, this option can only be changed by the game
host in the pre-game setup.
For both knobs, there is one pair of checkboxes to control this as a
player preference, which applies in single player games. There is a
second pair of checkboxes in the multiplayer setup, which applies only
to multiplayer games. Therefore, in multiplayer, the host chooses thief
settings and all clients use the host's choice. The host may configure
the thief differently in multiplayer from how the host plays in single
player.
For users who wanted to remove the thief, no specific tally has been
kept for who requested it or when. Now that the code is being updated,
this is thrown in as an easy addition.

Many of these locals are wasteful, since they are always sized to the
biggest buffer required. This is the minimal and safe solution. Future
work will tune them to the correct size.
`value` is generic and unclear. It is always meant to be used as an
index into the Station array, so rename it `station_idx` to show this.
Define and consistently use `station_none` to represent that no station
is assigned.
Delete stub "compiler-type_traits.h" header. Redirect all uses to the

All supported compilers have an acceptable <type_traits>. Commit
4cb3d46148 ("Move <type_traits> test to Cxx11RequiredFeature") made
<type_traits> support mandatory in August and no one has objected.
Remove the indirection and use namespace std directly for type_traits
members.
Previously, valptridx used PREFIX for allow-invalid+mutable, c#PREFIX
for allow-invalid+const, v#PREFIX for require-valid+mutable, vc#PREFIX
for require-valid+const. Convert the types, factories, and all usage
sites to specify a qualifier for all four combinations:
im#PREFIX -> allow-invalid+mutable
ic#PREFIX -> allow-invalid+const
vm#PREFIX -> require-valid+mutable
vc#PREFIX -> require-valid+const

Commit b32298df5a ("Rewrite powerup cap
code to centralize logic") centralized powerup cap code in the
powerup_cap_state class.
Commit 901a554e96 ("New powerup management
code: Addeed functions and packet type to ...") removed all use of
powerup_cap_state, but left the dead implementation present.
Commit 479f5ed584 ("Fix 'format specifies
type 'unsigned short' but the argument has type 'unsigned char''
warning") switched the already dead (but still compiled) code from %hu
to %hhu to fix a warning on OS X. Although the commit was written by
Chris, it was my suggestion to use %hhu. I neglected to test Windows
before suggesting it, so the change went in even though Windows does not
accept %hhu; this broke the Windows build. Fortunately, the code had
been dead for 11 months when the change was made, so the fix for Windows
is to remove the long dead code.
In multi_do_frame(), replace call to window_close(Game_wind) with returning window_event_result::close whenever multi_quit_game is true. Only using this return value where multi_do_frame() is directly called by GameProcessFrame(). multi_quit_game will only be set back to 0 when a new multi game is started.
Closing a window within its handler is problematic - it can result in an unstable state.

To recognize getaddrinfo as supported, require that the AI_* flags
passed to it be usable:
- AI_NUMERICSERV must be defined as a number or be undefined
- If ipv6=1, then AI_V4MAPPED and AI_ALL must be defined as numbers
When getaddrinfo is used, raise _WIN32_WINNT from 0x501 to 0x600.
Otherwise, lower it to 0x500.
The only caller for get_multi_endlevel_poll1 was DoEndLevelScoreGlitz,

All callers of MultiLevelInv_Count passed a constant value. Factor
out the top level blocks of MultiLevelInv_Count into helper functions,
then create two new functions corresponding to MultiLevelInv_Count(0)
and MultiLevelInv_Count(1), implemented by calling the appropriate new
helper functions.
