5909b9a1cf Isolate the Altivec code so non-Altivec PPC targets can use the same binary.
Moved all the code using Altivec intrinsics to separate files. This 
means we can optionally use GCC's -maltivec on just these files, which
are chosen at runtime if the CPU supports Altivec, and compile the rest
without it, making a single binary that has Altivec optimizations but
can still work on G3.

Unlike SSE and similar extensions on x86, there does not seem to be
a way to enable conditional, targeted use of Altivec based on runtime
detection (which is what ioquake3 wants to do) without also giving the
compiler permission to use Altivec in code generation; so to not crash
on CPUs that do not implement Altivec, we'll have to turn it off
altogether, except in translation units that are only entered when
runtime Altivec detection is successful.

This has been tested on Linux PPC (on an Altivec-enabled CPU),
but we may need further work after testing trickles out to other
PowerPC devices and ancient Mac OS X builds.

I did a little work on this patch, but the majority of the effort belongs 
to Simon McVittie (thanks!).

2326a060b9 Don't allow SDL audio capture using pulseaudio
When you start recording using SDL pulseaudio driver the client sends
all audio captured while not recording. 240 milliseconds of audio is
sent each frame until the capture buffer is empty. This is a problem for
privacy and causes confusing to debug VoIP playback issues on other
clients connected to server and when playing back demos.

42d2fb908c OpenGL2: Fix parsing specularScale in shaders
Fix specularScale <metallic> <smoothness> with r_pbr 1 which has been
broken since r_pbr was implemented in 2016.

Fix specularScale <r> <g> <b> <gloss> setting b to gloss and leaving
gloss as 0 since it was implemented in 2014.

10abac8fa0 Fix duplicate bots displayed in Team Arena ingame add bot menu
The key handler allowed going 2 beyond the end of the bot list and the
display function clamped to 0 causing the first bot to be shown 3 times.

Attempting to add the bot in gametypes < GT_TEAM would fallback to
Sarge in UI_GetBotNameByNumber() (who isn't the first bot) and gametypes
>= GT_TEAM would access characterList past known values (typically NULL
but if teaminfo.txt contained 63 characters it would access out of
bounds memory).

51743bbb01 Improvements for dedicated camera followers (team follow1/2)
Switching to dedicated camera follower with no possible players to
follow would spawn at the intermission point and display "connection
interrupted" HUD message. Pmove() was not run for the client so
ps.commandTime was too far behind. I made it so that dedicated camera
followers and scoreboard run Pmove() but cannot move (PM_FREEZE).

When all players possible to follow leave, the dedicated camera follower
would continue to display the old player state of the player they were
following (along with "connection interrupted" HUD message). Unlike the
regular case of a spectator following a specific player, dedicated
camera followers did not reset their player state to the intermission
point after the followed player was no longer valid.

Now a client can be set as 'team follow1' to automatically switch
between displaying the intermission point and following a player when
possible.

9a0ee67e04 Make macOS Universal Bundle target 10.6 for x86 and x86_64
SDL 2.0.5 dropped support for macOS 10.5 so target 10.6 instead. The
PPC build uses SDL 2.0.1 so it still targets 10.5. macOS 10.5 (x86,
x86_64) should automatically run the PPC build using Rosetta.

Revert MAN-AT-ARMS' change to SDL 2.0.8 SDL_platform.h that allowed
targeting macOS 10.5 for the sake of PPC. It also incorrectly allowed
x86 and x86_64 to target 10.5 as well. (Also macOS PPC uses separate
headers now.)

92935df37b Enable SDL audio capture for SDL 2.0.5 and newer

2.0.1 for PPC. Add 2.0.1 headers for PPC with modifed SDL_platform.h to
allow compiling using macOS 10.5 SDK. Using separate headers allows the
engine to check the SDL version for enabling newer SDL features.

78c70d0afc Use the SDL2 audio device interface instead of the legacy 1.2 API.
This is a little bit of future-proofing, but also gives us a little more
flexibility in general; now we can add in the cvars to open a specific
device, etc, that the OpenAL codepath does.

62acfb3348 sdl_snd.c should just initialize SDL audio without checking SDL_WasInit().
In SDL2, the initialized subsystems are referenced counted, so it's safe to
initialize them twice, and it makes the SDL_QuitSubSystem during our shutdown
correctly decrement the count. Before (as a probably-harmless bug), it would
not increment the refcount if the subsystem was already initialized, causing
problems when it decremented it later.

3377f9981a Fix map list in Team Arena start server menu after entering SP menu
In September 2017 I moved loading arenas.txt/*.arena files from entering
start server menu to at startup to fix running out of memory in Team Arena
UI after opening the start server menu several times.

However, Team Arena completely replaces the uiInfo.mapList array when
switching between single player and start server menus. So after my
change, entering single player and then entering start server would only
display single player maps. It caused SP endofgame menu to use MP map
list for replay/next map since arenas were loaded after gameinfo.txt.

Continue loading arena info at start up to avoid reallocating arena info
but move setting up uiInfo.mapList to when entering the start server
menu.

dfb49e78b5 Make setting r_stencilbits more consistent in Team Arena UI
I changed Color Depth options 'Default' to reset r_stencilbits instead
of 0 and '32 bit' to use r_stencilbits 8 instead of not changing the
value. (This matches my q3_ui changes in the previous commit.)

Set r_stencilbits when changing graphics presets like when changing
Color Depth.

61404e25c4 Restore setting r_colorbits in q3_ui
In 2007 in ioquake3 unified-sdl branch (revision 1144) setting
r_colorbits in q3_ui was removed but the Color Depth menu option was
still kept. Setting r_colorbits was not removed from the Team Arena UI.

In 2011 I removed the Color Depth menu option from q3_ui as it did not
change any cvars. Yesterday I restored the option not realizing this
and thinking that requesting 16-bit color depth worked.

Add setting r_colorbits back to q3_ui so Color Depth menu option works
again. I changed Color Depth options 'Default' to reset r_stencilbits
instead of 0 and '32 bit' to use r_stencilbits 8 instead of not changing
the value.

However I discovered r_colorbits 16 does not actually work on my system
(Debian Jessie x86_64 nvidia). ioquake3 was reporting the requested
value instead of the actual obtained value. Fixed in my previous commit.

43602a7eb8 Revert "Removed "Color Depth" from q3_ui system settings, it didn't control anything."
The r_colorbits cvar still exists and gfxinfo reports it works on
Debian Jessie in both git master and building the commit where I
removed r_colorbits from q3_ui. So it does indeed control something.
Maybe I expected 16-bit color to look different? I don't know.

3ad427c68d Fix q3history buffer not cleared between mods and OOB-access
Loading a 1024-byte q3history file will fill the whole consoleSaveBuffer
leaving no space for a string terminator. Com_Parse will read at least
one byte beyond the end of consoleSaveBuffer. The written console
history file can only be 1023 bytes (enforced by Q_strcat) so don't
allow loading size of 1024.

If switching to a mod with a shorter q3history file, the data in
consoleSaveBuffer that isn't overwritten will be parsed. So always
add a string terminator.

String not terminated reported by David "devnexen" CARLIER.

699cbed7c7 Fix mouse grab after toggling fullscreen
cls.glconfig.isFullscreen was not updated when changing r_fullscreen
without a vid_restart. Starting in fullscreen and switching to
windowed mode would not release the mouse.

Mods calling trap_GetGlconfig() after a fullscreen toggle now get
the correct value for isFullscreen. (Note: Mods already got the
correct value at start up and after vid_restart.)

b61e2998f3 Fix exploit to reset player by sending wrong serverId
If client sends wrong serverId but is already active in the world
(CS_ACTIVE) don't resend initial gamestate for the map. This isn't a
valid situation. The player should be CS_CONNECTED or CS_PRIMED.

Resending gamestate to an active player will cause them to respawn
without dying or disconnecting. If the player had a CTF flag it gets
lost until the map is changed or restarted.

484149573b Allow loading system OpenAL library on macOS again
In May 2017 the library loading was limited to *.dylib but the macOS
system OpenAL framework does not have dylib extension. So allow loading
files from /System/Library/Frameworks/ as libraries even without dylib
extension.

This is checked in Sys_DllExtension() so that QVM filesystem access will
not allow writing files to /System/Library/Frameworks/ even if homepath
is changed to include it. (Admittedly it doesn't fit the function name
but fits the function description and current usage.)
