Remove the `jumpabsolute` member from `mstatement_s`.
This reduces the struct from 20 to 16 bytes, and thus may save some
RAM. It also may improve CPU cache behavior by keeping more QC code in
L1 and L2 cache, and possibly also improve instruction processing inside
the CPU as all statements are aligned the same way.
On `srv04`, this speeds up Xonotic's `serverbench` from 58.92s real,
57.72s user to 57.72s real, 56.59s user (median of 25).
Since that cvar was implemented, unix time has grown too large to be
represented precisely by a float, causing FPS to be much lower than
configured. Should be using host.realtime (relative) here anyway.
Simplifies Curl_Select() and improves some debug messages.
So we can work around its bug (race condition) that makes start.bsp
unplayble sometimes because apparently DP is faster at connecting the
local client than some other engines, and this mod relies on it taking
longer.
host: make some startup errors non-fatal, related polishing and cleanup
It's annoying to abort DP just because of a bad menu progs or demo,
especially on Windows where accessing stdout is difficult so console
access is more important.
Shows a correct fallback message when the menu progs crashes (it's not
because of missing files).
Makes the missing files message more concise.
Performs a full cleanup after any QC crash, most importantly
progs->loaded is now false until that VM is restarted successfully.
Prevents menu failure interfering with more important VMs.
Removes the weird "early frame abort" jump point which is redundant now
because Host_Error, now the only code that ever aborts a frame, calls
Sys_Error instead of Host_AbortCurrentFrame during init.
Changes the framecount of the first frame from 0 to 1 so that when it's
>0 that means frame abort is now possible and safe.
When inactive/minimised with snd_mutewhenidle enabled, the audio capture
was unreliable and sound was sometimes output when it should have been
muted.
Closes https://gitlab.com/xonotic/darkplaces/-/issues/92
(the video issue was already fixed).
Timedemos now share the same mute implementation as snd_mutewhenidle.
Ignores refresh requests while a refresh is in progress.
This prevents live servers getting timed out, which sometimes happened
when Xonotic menu QC responded to a server list mouseover event.
Fixes incorrect types in timeout check and ping comparison.

Reduce the amount of unnecessary messages shown in the game chat
Some engine messages are being printed to chat in scenarios where they may obscure regular game chat.
To help with this, I've adjusted the visibility of them:
- "unconnected changed name to BOT" and "BOT left the game" showing in chat have been disabled by only allowing such messages to show for real clients
Bots will still show that they've been dropped in the console and Xonotic still shows a (dis)connect message
- Verbose "Server lag report" messages (most commonly seen during map votes) have been moved to the console

edict: fix escape parsing and make exceptions configurable
In 312123ecffc7e3dd892c7df754c911b47b9cdfaa a bug was introduced where
newlines were no longer supported in string fields.
This patch supports them again, which requires exceptions be
reintroduced to fully support some buggy maps, but this time there's a
cvar for documentation and adjustment. The other notes and fixes in
https://github.com/DarkPlacesEngine/darkplaces/pull/185 still apply.
The code introduced in 42e86ab7892c3d8f5373402a714b73b2e040d81b had two
separate modes which was more complex than necessary and less robust in
high ping high jitter scenarios.
The 0ms packet check didn't work when the cause was aggressive time
synchronisation and a ping spike.
In 3d8f1ca7b142c0a9fd8c3b4a494b62dcce39ab71 a horizontal player speed
calculation was changed to include the vertical velocity and to no
longer be the speed, by use of the wrong macro.
This patch reverts those changes and adds a macro for this calculation.

fs: recognise mods by -game cmdline args, deduplicate gamedirs, refactoring
Players often start mods using -game even when they have their own

Refactoring was required to avoid chicken vs egg problems when doing it
with cmdline gamedirs too.
Fixes a bug: the first gamedir (in the cmdline or `gamedir` args) was
used to identify the mod but it needs to be the last one that matches
because the last gamedir is the primary (first in the search path, and
where files are saved).
Includes supported game and mod directories in the main gamedir list for
interface consistency, less special cases, and to support deduplication.
Refactoring was required in the menu modlist where there was also an
