Fix most Q3 & QL glow maps
From bones_was_here: "Very few glow maps work in unmodified Q3 maps as they do not use the _glow darkplaces convention, instead Q3 shaders specify the file name to use which is not currently supported.
Fortunately there is a naming convention started in id software's pak0 and continued in QL and most 3rd party maps. It uses these forms: foo_texture.blend.ext and bar_texture_blend.ext
It's not possible to fix 100% of glow maps without parsing Q3 shaders and using the specified file name, but this is a big improvement.
This also fixes a few glow maps in nexcompat, which are originally Q3 textures that were not renamed to _glow."

Fix the corona bug. The render bug only though.
This is done by reviving alphamod and colormod arguments of
RSurf_ActiveCustomEntity.
The current implementation is a bit rough and needlessly copies the
worldentity; the struct isn't huge though and it's only done when
actually colormodding (and thus only for coronas, r_editlights, a few
sprites and nomodels).
Refactored R_UpdateEntityLighting to CL_UpdateEntityShading, which sets fields like ent->render_modellight_ambient.
Added texture->render_modellight_ambient and similar fields which concretely define how the material is to be rendered, so all of the various tweaks and modifiers are no longer buried in R_SetupShader_Surface which has now been refactored heavily.
Removed R_LightPoint as it's really not necessary - this change will make lit particles a little bit slower as R_CompleteLightPoint is a slightly more expensive function.
Refactored R_CompleteLightPoint to have more consistent code, changed the final color math so that it passes q1bsp/q2bsp lighting through unmodified.
Changed shading of tag_entity attachments - they now use the root entity's origin for shading, this fixes r_shadows where the shadows could go in different directions on CSQC entities (r_shadows code already contained a hack to work around this problem for network entities).
Renamed r_refdef.lightmapintensity and ambient to r_refdef.scene.lightmapintensity and ambientintensity.

Another flag bites the dust. This time: -ffinite-math-only.
Since GCC 5, with this flag set, NaN compares equal to zero in some cases but
not others. Causes e.g. "attempted division by zero" error spam from this QC
code:
float x = nan("");
if (x == 0) {
return 0;
}
return 1.0 / x;
Yes, those NaNs should not be happening in the first place, but suddenly
passing some but not all equality checks to zero seems rather dangerous.
Reference: issue #2412 (not a fix for it; the QC code has a problem too but
this change helps track it down properly).
After migrating to SDL2 interfaces there is noise during startup fix
this by initializng buffer as specification requires.
Per SDL_AudioCallback spec:
The callback must completely initialize the buffer; as of SDL 2.0, this buffer is not initialized before the callback is called. If there is nothing to play, the callback should fill the buffer with silence.
Make the semantics of CL_VM_UpdateView more clear - if CSQC is loaded, it is required to provide the CSQC_UpdateView function, and won't render a view if it does not call that, so we don't need to check its return value.
New alternative to fullbright: r_fullbright_directed.
Set this to 1, and anything EF_FULLBRIGHT or fullbright due to
r_fullbright or unlit map (but specifically not sprites and surfaces
with surfaceparm nolightmap) will have a directional effect applied to
them.
This mode is intended for testing maps in early development, and should
not be used for normal gameplay (although it should be rather harmless
there).
Manage resetting the key event state on video reinitialization centrally.
Fixes:
- No key state clear when SDL gets restarted.
- Key state clear was the wrong action - it allows all keys to get pressed
again, but does not actually release anything in cl_input.c, so e.g. +jump
binds stay pressed on vid_restart.
Only vid_wgl.c retains some vid-specific handling (reset of key state when
alt-tabbing out and back in) - there's a chance that we may need similar logic
in the other vid drivers; if so, it may be possible to do this in a shared
place too by watching for changes to vid_activewindow.

This also fixes a popping issue with r_shadow_deferred 1 where the eye was not in a leaf the light considered to be visible, and thus the light was not drawn (which made quite a difference when you move back and forth between leafs that were and were not lit), since when it was drawn it lit everything in the area.

SDL2: combine SDL_KEYDOWN events directly with following SDL_TEXTINPUT events when possible.
This solves ` keypresses that open/close the console also typing in a character
"once and for all". The ability to type the ` character into the console is not
impaired by this as con_closeontoggleconsole's logic to by default ignore the
toggleconsole key when in the console but not at the beginning of the line
still applies.
rcon server: add an explicit check against empty password, instead of assuming the calling code is correct.
This logic had a bug in the past that had been introduced by r8886 and
accidentally fixed when introducing multi-account support in r9420. The bug was
that rcon_password being empty led to the empty password being accepted in some
cases, as there was never any explicit logic to handle that in rcon - it was
more "accidentally" rejected by a packet formatting check which does not apply
to srcon as the empty password wouldn't be empty over the wire.
In other words: DP builds from [r8886, r9419] had a serious vulnerability and
the only workaround is to always have rcon_password set.
The check added here will complain and reject in case the calling code for some
reason no longer prevents empty passwords from being accepted.
Also adding comments to the new logic explaining how it prevents the empty
password from being accepted.
