This brings NQ's physics a little closer to QW's. After studying both the
original WinQuake source and the progs source, this change should be
harmless, making very little difference. However, it does allow an
entity's think function to be called multiple times in the same frame (for
when the entity needs more time to think, but it would cause runaway loop
errors). Maybe need a "runaway think" check.
This has several benifits:
o The silly issue with alias model pitches being backwards is kept out
of the renderer (it's a quakec thing: entites do their pitch
backwards, but originally, only alias models were rotated. Hipnotic
did brush entity rotations in the correct direction).
o Angle to frame vector conversions are done only when the entity's
angles vector changes, rather than every frame. This avoids a lot of
unnecessary trig function calls.
o Once transformed, an entity's frame vectors are always available.
However, the vectors are left handed rather than right handed (ie,
forward/left/up instead of forward/right/up): just a matter of
watching the sign. This avoids even more trig calls (flag models in
qw).
o This paves the way for merging brush entity surface rendering with the
world model surface rendering (the actual goal of this patch).
o This also paves the way for using quaternions to represent entity
orientation, as that would be a protocol change.
There are some problems with menus and the console messing up the key_dest
state (they assume console/menu or game, nothing else), but otherwise
things seem to work.
I got rather tired of there being multiple definitions of mostly compatible
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.
Currently only "id", "hipnotic" and "rogue" are supported (anything else is
treated as "id"). Has no effect in quakeworld (good thing too: changing
gamedirs is a little broken).
If a tossed entity has ONGROUND set, it won't move, but if it has an upward
velocity, it can't possibly be ONGROUND, so clear the flag if the entity is
moving upwards.
This also makes functionality consistent across the platforms, such as
adding support for -dedicated to sdl based nq, and various timing
calculations are now consistent.
It seems qsockaddr's assumptions aren't necessarily portable, as OpenBSD
seems to be doing weird things with qsa_family. Even if that's not the
case, this is cleaner.

As this might break the gameplay of certain maps, the new sv_jump_any
cvar can be used to disable this feature (bringing back the old behavior).
in_dga -> 0 (until X is fixed)
gl_multitexture -> 1 (why was this 0? not enough support back then?)
cl_usleep -> 1 (seems to be ok)
host_mem_size -> 40 (even 32 isn't enough these days)
rate -> 10000 (we're not in the modem era any more)
cl_mem_size -> 32 (16 is not enough, 32 sounds better than 24)
This is based on the code presented on
http://forums.inside3d.com/viewtopic.php?t=2376 (and updates linked from
that thread), but with modifications for hopefully supporting rotating
trains (and not duplicating big fuctions).
For now, only nq. qw will come after some more testing.
This fixes the hang after a few (3 or 4) play/timedemo runs of bigass1. Now
23 runs (and counting) seems to work well, though there seems to be a
memory leak somewhere.
nq's SV_CheckVelocity will be a little different (spherical rather than
cubical), but sv_maxvelocity defaults high enough for it to not matter to
most players. It might even improve play.
The remaining differences need some careful thought before the physics
merge is done.
This allows the pvs to be used on an antity no matter how many leafs the
entity is touching. Seems to work nicely, but it will leak memory every
time a map is loaded.
This reverts commit ad7e7e45fe.
The cleanup broke entity linking, but fixing it would just duplicate the
previous tests, so might as well revert. Cleaning up the interpolation code
is probably a better approach.
Here's a patch to NET_SendToAll() which was always
broken: it never skipped non-connected clients.
Depending on the compiler, it would wait the whole
5 seconds of its blocktime before it gave up.
While there, changed its blocktime argument to
double (the comparison is against a double.)
Most of the guts of configure.ac have been moved to config.d and are then
brought in by m4_include. This will make maintaining configure.ac much easier.
Also drop use of PROGRAM and VERSION, using PACKAGE_NAME, PACKAGE_VERSION, and
on occasion, PACKAGE_STRING instead, and clean out some old files we no longer
need.
