Elric's changes:
JPEG texture loading using libjpeg (entirely optional at runtime - if not present, it won't load it)
gl_extensionfunctionlist_t is now renamed dllfunction_t and part of a shared system for library opening/function retrieval (functions Sys_LoadLibrary, Sys_GetProcAddress, Sys_UnloadLibrary - for this the library handles are considered void *'s)
LordHavoc's changes:
fixed libjpeg support in non-win32 by using jpeglib.h - honors jpeglib.h's idea of boolean - Linux libjpeg is compiled with boolean as int, unlike windows where it is apparently byte - unfortunately this also means you need libjpeg-devel installed to compile it in non-win32, not sure what can be done about this (but most people seem to have that anyway...)
looks for libjpeg.so.62 instead of libjpeg.so

glossmap textures are now brighter (no change to forced gloss brightness)
now clears lights when reloading lights
r_editlights_quakelightsizescale cvar added, default 0.8, controls size of lights imported from maps, gets a major speed gain but makes the map a little darker
R_Shadow_NewWorldLight now checks if radius or color is too dim and won't spawn such lights
in editing mode the centers of lights are visible now (as crosshair images)
light selection is now done a bit differently - the more precisely you point at a light, the higher it's rating gets, sometimes surpassing the closer lights in the area

now clears stencil to 128 instead of 0, this avoids problems with arbitrary incr/decr orders
stencil shadows are now always erased by glClear, never by drawing again, removes r_shadow_erasebydrawing cvar
shadow volumes now have a nudge away from the surface that cast them, this is controlled by the r_shadow_shadownudge cvar (default 1 unit), avoids rare z fighting issues
shadow volume projection distance is now not infinite for alias model volumes, because they are more well-behaved than the world shadows...
msurface_t poly_radius and poly_radius2 removed
now validates elements in more parts of loading (hoped this would reveal a model shadow bug, but it didn't)
Mod_ShadowMesh_AddVertex now uses a hash table search to speed up static shadow volume building (unfortunately this doesn't seem to be the real speed problem)
removed ALLOCMESHINPIECES option from Mod_ShadowMesh code
removed non-PRECOMPUTEDSHADOWVOLUMES option from static shadow volume creation
removed some unused variables

bumpscale is now adjustable (r_shadow_bumpscale) for experimenting (it's not saved to config)
.lights loading now has the correct light intensity
torchs now spawn lights above their location so the shadow is cast down, not up

changed how QC interpreter handles edict field access - the entvars struct is now a pointer - yes this changed that many files...
discovered gcc 2.95.3 is the sole cause of map change crashs in the QC interpreter - it does not compile pr_exec.c correctly somehow (I think OP_ADDRESS is the only place it has a problem), makefile now refers to gcc-3.1 (maybe this should be changed, but oh well for now)

gloss now works correctly
major speedups to realtime lighting mode (it's now actually playable on my machine)
world lights are now handled by r_shadow.c instead of the lights list in the world model
world lights can be ingame edited/loaded/saved (the file name ends in .rtlights), this is all controlled by r_editlights* commands/cvars
realtime lighting cvars renamed from r_light_* to r_shadow_*
r_shadow_realtime takes the place of r_shadows modes 2 and 3, mode 1 is realtime lighting, mode 2 is realtime lighting plus visible shadow volumes overlaid
r_shadow_lightingmode variable added (updated each frame) indicating whether or not realtime lighting is active
changed how player model and chase_active is handled (player model is now considered a forced RENDER_EXTERIORMODEL), so player now casts shadows
R_Shadow_Volume no longer takes a vertex parameter, it is implied that it is in varray_vertex (since all the code relied on this fact anyway)
R_Shadow_Volume's code has been split out into reusable functions (R_Shadow_ProjectVertices, R_Shadow_MakeTriangleShadowFlags, R_Shadow_BuildShadowVolumeTriangles)
R_Shadow_RenderLighting split into R_Shadow_DiffuseLighting and R_Shadow_SpecularLighting since sometimes it's usable to use more than one call to diffuse lighting (colormapped models)
R_Model_Alias_DrawLight now handles colormapping
added Light_CullBox and LightAndVis_CullBox functions for culling shadow volumes
R_DrawWorldLightShadowVolume has been moved to r_shadow.c
Mod_ShadowMesh_Begin now takes an initial number of triangles to hold, number of triangles in each additional shadowmesh is now based on previous mesh
R_Model_Brush_DrawLightForSurfaceList added to greatly reduce wasted lighting
rewrote visibility logic in R_Model_Brush_DrawLight, now uses different approachs for bmodels and world
lights are now pvs culled (according to what leafs are visible to the viewer, and what leafs are visible to the light)
R_Shadow_Stage_EraseShadowVolumes now returns an int, indicating whether or not to draw the shadow volumes again to erase
rewrote how texture info based on entity and time is updated (it is now a function called R_UpdateTextureInfo)
fixed a ton of bugs relating to animated textures and transparency of bmodels (also changed texture_t currentframe to no longer be an array)
disabled building of surface neighbors (oh sure I made it a lot faster and stuff, but it's still not practical, and is no longer necessary)
changed parameters of model_t DrawLight function to no longer take distbias and subtract
Mod_ProcessLightList is no longer called
mlight_t fields relating to shadow volumes have been commented out
Mod_ValidateElements function added
notes on enormous cost added to Mod_BuildTextureVectorsAndNormals (188 float operations per triangle, and 39 float operations per vertex)
added (disabled) code for allocating and freeing shadowmeshs in pieces, just for obsessive memory corruption detection (none was found)
Mod_ShadowMesh_AddTriangle and Mod_ShadowMesh_AddMesh functions added, and Mod_ShadowMesh_AddPolygon now uses AddTriangle (this is a slowdown but I'm not sure it matters that it is, it fills out meshs more completely)
added (disabled) code for Mod_ShadowMesh_Finish to work without reallocating meshs
R_Shadow_ResizeTriangleFacingLight and R_Shadow_ResizeShadowElements added
R_Shadow_RenderShadowMeshVolume added (properly renders shadowmesh_t chains, fixing all the bugs with static shadow volume rendering)
r_shadow_blankbumptexture is now 1x1
r_shadow_blankglosstexture and r_shadow_blankwhitetexture added (both 1x1)
added a 4 texture path for r_shadowtexture3d 0 mode
when static shadow volumes are constructed for world lights, it is now done by constructing a combined mesh of all lit geometry, and then casting shadows from that (this reduces shadow volume edges greatly, since separate polygons become a continuous mesh during the mesh creation)

reworked visibility a bit (added VIS_CullBox and VIS_CullSphere) so it can be pretty accurate
made pvs surface/leaf lists to make R_SurfaceWorldNode as fast as possible
world geometry now casts shadows from frontfaces instead of backfaces
fixed most shadowing bugs
static shadow volumes now work (other than one bug I'm trying to find) and are on by default

reorganized how heartbeat timing works (much simpler and cleaner now)
sv_heartbeatperiod controls how often a heartbeat is sent
sv_public controls whether heartbeats are sent at all (default: 0)

Added a test when freeing textures (glt->image can be NULL if the program exits because of a lack of memory at startup). Also, Transfusion doesn't have a "start" map, so Transfusion dedicated servers shouldn't use it as their default map. Removed a preprocessor warning in r_shadow.c

model->DrawBaseLighting function is gone, now just a few special cases in the normal Draw function
removed R_NotCulledBox
added PVS_CullBox, R_CullSphere, and PVS_CullSphere
visiblevolume flag is gone from shadow rendering code (visible volumes are now automatic depending on what stage the shadow system is in)
R_DrawShadowVolumes is gone (now just a special option to R_ShadowVolumeLighting)
cubemap textures now upload correctly
doubled the bumpyness of surfaces to make bumpmapping noticable (still less than tenebrae)
fixed crash when loading external map textures
now supports _luma as an alternate name for _glow map textures (tenebrae compatibility)
can now override _bump, _gloss, and _glow/_luma textures that were generated from the map
bumpmapping works on the map now (that was a stupid typo...)
now uses alpha buffering for multi-pass lighting effects
r_shadows 3 now works on Geforce2 (2tex no3D 3 pass per layer) and Radeon (2tex 3D 2 pass per layer - Radeon has 3 texture units but the lighting code is most efficient with 2 units, and 3D textures use up 2 texture units on Radeon... lame...)
gloss isn't working yet
r_shadows 3 mode supports up to 64x overbright lighting now (by rendering light multiple times)

surface meshs are now allocated by a single function to simplify things
more heavy construction on static shadow volumes (which aren't working correctly)
VectorNormalize, VectorNormalize2, and VectorNormalizeDouble macros no longer produce infinite vectors if given null vectors
corrected names of dot3 enums

added GL_SetupView_Mode_PerspectiveInfiniteFarClip based on code from tenebrae
texture state management now has combinergb and combinealpha for each texture unit
aliasvert array went away
aliasvert_svectors, aliasvert_tvectors, and aliasvert_normals added (note: padded to 4 floats)

shadow functions now take a vertex array pointer, to make them more broadly useful (in precomputation perhaps?)
beginning work on a precomputed shadow volumes system for static lights
bmodel shadow volumes
static lights (in maps with .lights files) now cast shadow volumes (this combined with the above makes dpdm1 and dpdm2 unplayably slow - need to do precomputed world shadow volumes)
(note: like the previous shadow volume commits, this is still just visible volumes when you use r_shadows 2, purely experimental still)
