Rework R_CanSeeBox a bit to support an eyejitter feature, and make it available throughout the renderer.
Make TraceLineOfSight check if the trace endpos is within a box, not just if fraction is 1 - this makes it much more likely to say an object is visible when the object overlaps walls and other obstacles as the rays only need to reach the box, it doesn't matter much where it goes inside the box.

Change shadowless rtlights so that they are not occluded by anything - no pvs checks or portal culling.
This makes r_shadow_deferred 0 look the same as r_shadow_deferred 1 - lights fill their whole area if there are no shadows to block them.
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.

Don't set MATERIALFLAG_NOSHADOW on SKY materials. They need to cast shadows to prevent issues in e1m7 and other cases where sky occludes light bleed into other areas.
But when loading Q1BSP, set MATERIALFLAG_NOSHADOW on SKY if it has non-SOLID contents behind it, this supports the e1m5 logo shadow trick.

Use the invariant keyword on gl_Position on GLSL 1.20 or higher and GLSL ES
1.00 or higher, this should resolve zfighting between light polygons and
base surfaces.
A long long time ago this was using ftransform() which ensured invariance but use of the invariant keyword was not added when we switched away from that.

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.
Fix a bug in collisions between brushes and brushes when the plane is rotating - this case is never used currently but it's definitely a bug worth fixing.
Fix bugs in ModList_RebuildList such that it no longer lists files in the quake directory as gamedirs.
These bugs were previously hidden by a different behavior in FS_CheckNastyPath until 20140716 where directories with a period in their name were skipped, but that was not a complete solution.

Use tighter bounds for bouncegrid texture
Calculate bounds enclosing all lights instead of using the world bounds.
Maps with unlit monster containers such as e1m7 benefit from reduced RAM usage.
The input destination is toggled on the first event, and the console then would

queued into the console buffer, and executed at the end of the frame!

Rewrote bouncegrid path splatting, it now has a cone shape which grows with distance, which reduces the splotchy look (cvars r_shadow_bouncegrid_lightpathsize_initial and r_shadow_bouncegrid_lightpathsize_conespread control this).
Replaced r_shadow_bouncegrid_(static|dynamic)_energyperphoton with r_shadow_bouncegrid_(static|dynamic)_quality cvar which works opposite the old one and is automatically multiplied by spacing^2 so you no longer have to hand-tune it when changing spacing.
Turned off r_shadow_bouncegrid_blur by default - it's still useful but no longer completely necessary.
Replaced r_shadow_bouncegrid_dynamic_stablerandom with r_shadow_bouncegrid_rng_type (which defaults to Lehmer 128bit RNG) and added r_shadow_bouncegrid_rng_seed (which can be set to -1 for the time-based random that stablerandom <= 0 used to trigger).

Add skipsupercontentsmask parameter to all the collision implementations, this allows you to ignore brushes/surfaces matching the specified contents flags, the primary use is ignoring q1bsp sky surfaces which are SUPERCONTENTS_SKY and SUPERCONTENTS_SOLID, since SUPERCONTENTS_SOLID is in the hitsupercontentsmask it will normally block on sky surfaces, but this way it will not if they also have SUPERCONTENTS_SKY set.

Added cl_bob_limit_heightcheck cvar (off by default) which uses tracelines to limit the maximum value of cl_bob_limit based on the ceiling and floor height.

Overhauled quake3 shader loading such that it now produces shader passes that could render the material mostly correctly (rendering not yet implemented for the pre/post passes the logic identifies).
Main visible effect of this is that quake3 maps look more correct, but don't have any fancy effects yet.

Fix Q2BSP texture loading, Q2BSP contents issues, and add support for SURF_ALPHATEST for any maps that might use it, force fullbright rendering on SURF_TRANS33/SURF_TRANS66/SURF_WARP textures which fixes the rain in 3v3gloom3.bsp and chainlink fence textures on tkse.bsp and glass transparency on gloom1se.bsp among others. Also fix the SURF_FLOWING scroll rate when combined with SURF_WARP.
Also fixed the collision issues caused by stomping over Q1BSP data which caused traceline to break on Q1BSP after loading a Q2BSP map, thanks Supa for that bug report and finding other Q2BSP issues.
Changed naming of glsl/default.glsl and hlsl/default.hlsl to glsl/combined_crc*.glsl and hlsl/combined_crc*.hlsl - these are now effectively versioned by the crc of the builtin shader code, so if customization is applied it must match the current crc of the engine shader.
This should prevent any future shader version compatibility issues (at the cost of customization being harder to maintain).
Refactored shadermodeinfo related code to clean it up and make it more maintainable.
Overhauled shadowmap rendering to use an atlas texture, this is overall a speed loss on default settings (-7.7% fps on timedemo demo1, or -3% with r_shadow_deferred) but a gain on realtime world lighting (+21.1% normal, +1.7% with r_shadow_deferred) on NVIDIA GTX 680.
On video drivers with higher framebuffer switching costs, this should be a framerate gain in all situations.
Feature-wise this brings support (in future) for shadowmapping on transparent lit surfaces, and imposes an upper bound on how many pixels of shadowmaps will be rendered in a frame (shadowmap resolution automatically becomes more coarse on frames where they do not fit).
