Don't wash out HDR vertex lite surfaces in OpenGL2

Vertex lite surfaces being brighter than light maps looks bad,
they're meant to look the same. Especially in ET, which mixes
them fequently. It's noticeable in Q3 too though.

BSP lightmaps (i.e. not external HDR lightmaps) use
R_ColorShiftLightingBytes, now *Floats (used by vertex colors)
has the same behavior.

This may be a problem for HDR lightmaps, as the RGB will always be
scaled to 0.0 to 1.0 range.

I had enabled this for non-HDR before, but now HDR needs it too.
Update SDL 1.2.15 to Revision 8040
Fix error handling in R_ParseSpawnVars

When R_GetEntityToken returns qfalse it resets pointer for parsing, by
R_ParseSpawnVars not returning qfalse it could cause an infinite loop.

Also add newlines to printfs.
Don't say cubemap is outside lightgrid 6 times
Fix R_GetEntityToken ending prematurely

If spawn var key or value is "" it caused R_GetEntityToken (available to
cgame, used by opengl2) to stop parsing, whereas game VM would continue.

Changed it to match parsing used for game VM
(see G_GET_ENTITY_TOKEN in code/server/sv_game.c).

The map poq3dm5 has a "wait" key with value "".
Fix typo in animMap and videoMap warnings
Parse q3map_sunExt in OpenGL1 too

Used for drawing sun, which is supported by both OpenGL1 and OpenGL2.
OpenGL2 already parses it.
Don't mix sfx with NULL soundData

Caused a crash. Already done for looping sounds.
DMA 44100Hz needs more memory for sound buffers

It doubles the size of the data compared to the default (22050),
so increase the buffer automatically. Likewise, decreasing speed
doesn't need as much (though that doesn't really matter).
Bunch of comment fixes
Merge pull request #60 from smokin-guns/master

OpenGL2: Parallax corrected cubemap (cheaper trick)
Revert "DMA 44100Hz needs more memory for sound buffers"

This reverts commit 0e6632f464c08dcb76f26a52f33d97228e64fda1.

Cause crashes if com_soundMegs is 32.
Fix FS_FOpenFileReadDir non-zero file handle when file not found in pk3

If a pk3 search path is passed to FS_FOpenFileReadDir, a non-zero
file handle is returned if file is not found. This causes incorrect
behavior in FS_ReadFileDir (when a pk3 search path is passed in)
which only checks file handle, not length, for seeing if file exists.

I don't know of any issues in ioq3 caused by this.
