Check for truncated paths which could allow loading a library with
a non-standard extension. Also provides a better message for why a
valid library with a long path would fail to load.
Processing a callvote command after a vote passed to change maps but
has not been executed yet will result in 1) map change immediately
happening 2) after new map loads players have vote HUD messages but
Game VM doesn't have a vote in progress. The phantom vote status will
only be removed if players start a new vote or run vid_restart.
The underlying issue is that a second callvote sets vote config
strings but a map change is executed before they are sent to clients.
Resulting in clients getting "cs" reliable commands with the config
string changes _after_ the map change. Out of sync config strings.
Even if the underlying issue was fixed, the second vote would be lost.
So it's best to not force a map change to happen immediately anyway.

- Paths to search for mods are now specified in an array
- Mods can now consist solely of ".pk3dir" folders and still be
considered valid
- The function now has a consistent style
+seta, +sets, and +setu were ignored because Com_AddStartupCommands
thought Com_StartupVariable handled it.
+set didn't allow value to be multiple tokens which due to Unix shell
unintuitively removing quotes causes the variable to only be set to
the first token. This could be worked around by escaping quotes
ioq3ded +set g_motd \"hello world\"
but it doesn't match behavior of other start up commands (which now
includes seta, sets, and setu) that use all tokens.
source_t filename and includepath are 1024 but MAX_PATH is 64. As far as
I know the paths don't exceed that so this probably doesn't fix anything.
Similar changes were already made to l_script.c so this makes things
consistent. This was found because it was fixed in RTCW's code.
MISSIONPACK define is already required for this file or else it triggers an #error at the top of the file - removing redundant test that will never occur.
gcc 6 with -Wall -Wextra warns:

Modern compilers either ignore the register storage class when
generating code, or generate better code without it, so just remove
most of them.
The remaining uses are in third-party bundled libraries (libjpeg, zlib),
and in a PowerPC-specific inline function consisting of inline
assembler (because I'm not 100% confident that it doesn't have
some practical use there).
If ERR_DROP during Com_GameRestart after shutting down client, Com_Error
needs to restart the client otherwise there is just a black window. Also,
clear the game restarting flag in Com_Error otherwise it's not possible to
run Com_GameRestart again later.
I don't know of a way to trigger ERR_DROP, in FS_Restart for instance,
without engine changes however.
Offer to restore settings when loading a mod that crashed, not the first
mod that gets loaded after a crash. Before the first mod loaded (usually
baseq3) would get the option even if missionpack or some other mod crashed.
- Make pid files separate for each fs_game.
- Remove/write pid every time switching fs_game.
- Create path before writing pid file otherwise it fails on first run.
- Show mod description.txt or fs_game instead of engine name in abnormal
exit message.
- Check com_fullyInitialized in Com_Error before removing PID,
otherwise "ioquake3 --version" segfaults when accessing fs_gamevar->string
(plus not fully initialized isn't really a normal shutdown).
As with the other branch of the if/else, each element of
foundPlayerServerNames is in fact the same size as each element of
foundPlayerServerAddresses, so it was fine; but it's better to make
it obvious that we are using the right array sizes.
This function is used in the Team Arena menus
I don't think it's actually possible to reach this line with
foundPlayerServerNames < 1, because by the time we get here we have
set it to 1 + the actual number of servers; but if we did, it would
clearly underflow into foundPlayerServerNames[-1], which would be
undefined behaviour. gcc 6 diagnoses this with a warning:
code/ui/ui_main.c: In function ‘UI_BuildFindPlayerList’:
code/ui/ui_main.c:4138:16: warning: array subscript is below array bounds [-Warray-bounds]
Also correct the sizeof() invocation to make it more obviously
correct (in fact the buffers for names and addresses happen to both
be of size MAX_ADDRESSLENGTH, so it was fine, but it's good to be
obvious).
Given an array b[] of length n, pointers to &b[0]..&b[n] are defined
(where only &b[0]..&b[n-1] can be validly dereferenced). &b[-1], or
equivalently b-1, is not something we can use in valid Standard C.
gcc 6 diagnoses this as:
code/client/snd_wavelet.c:33:9: warning: array subscript is below array bounds [-Warray-bounds]
and might take this undefined behaviour as permission to emit
"more efficient" object code that is not what the author expected,
for example nothing at all. Use a macro to fake a 1-based array instead.
The goal of reproducible builds is that a rebuild of the same source
code with the same compiler, libraries, etc. should result in the same
binaries. SOURCE_DATE_EPOCH provides a standard way for build systems
to fill in the date of the latest source change, typically from a git
commit or from metadata like the debian/changelog in Debian packages.
This does not change anything if SOURCE_DATE_EPOCH is not defined;
the intention is that a larger build system like a Debian package
will define it.
Please see https://reproducible-builds.org/ for more information about
reproducible builds.
