f6f8394b74 Ensure that all keys are marked up when playing cinematics
Otherwise at least one key may be still marked as down causing an
immediate abort of playback. While here be a little bit paranoid
and clean up key states when focus is gained. In theory that's a
no-op.

f41f96e899 Use correct texture coordinates when drawing the video
When the video is scaled through OpenGL we can just throw it on our
vertexes and everything's alright. But when we're softscaling the video
we must consider that the videos size doesn't really match the vertex
size...

051be8285d Fix (text in) videos (for GPUs supporting NPOT textures)
especially in the intermission videos, the text looked broken, as parts
of the characters were missing.
This is because Draw_StretchRaw() converts the 320x240 video frame into
a 256x256 texture, without doing proper interpolation (just skipping
some pixels instead).
Now, if the GPU supports non-power-of-two texture sizes, the video
frames are uploaded as textures in their original size.

(Also fixed a harmless typo in common.h)

5e5217e549 Fix a rare crash in flyer.c with self->enemy being NULL
This crash was found by DanielGibson, he even guessed the right fix
without having a usable coredump. ;) In boss1.bsp Macron is waiting for
the player, despawning as soon as the player moves to him. After that
the player needs to press 2 buttons, each button triggers 3 flyers. If
the player is fast enough, the first bunch of flyers may spawn before
macron is despawned. Now there's a small chance that a flyer decides to
attack macron... If Macron despwans at the the next frame, self->enemy
is set to NULL (Macron is gone) but nevertheless flyer_fire() is called.

The correct fix would be to call flyer_fire() before Macron despawns,
but that's hard to impossible. So take the easy route and check if
self->enemy is not NULL.

548c217da8 Fix wrong monster count in city3.bsp
In city3.bsd ("Upper Palace") a hidden and unaccessible room next to the
security pass exists. In this room a grenate launcher and a pack of
grenates can be found. When the room is entered, two floaters are
triggered nearby. This can never happen, so the player is unable to
reach the goal of killing 75 monsters. Quirk around this by lowering
the total number of monsters by 2.

This bug has been known for a long time:

882297c33e Fix monsters blocking when not on ground entity
This bug was "fixed" by id with removing two lines in the ground entity
check. When cleaning up the game I added them back... I don't know if
it's really correct to just remove them, but let's try it. This fixes
issue #157.

aa897e3965 Make OSTYPE and ARCH user defineable.
The old implementation had two problems:

  * OSTYPE and ARCH are systemwide defines, overriding them may break
    the global libc headers. This is a theoretical problem, I've never
    seen it in praxis.

  * Not all system set ARCH correctly when building in a chroot env.
    For example on Linux ARCH is set to x86_64 when building in an
    i386 chroot. Now the user can do something like "make YQ2ARCH=i386"
    to get things right.

5d440bbb00 Make debris SOLID_NOT, fixes #154
In lower mines you can drop a rock onto a tank by using a lever.
This was broken, the rock exploded instead of dropping, because debris
is spawned and that debris was solid.
Now the debris is not solid anymore (like it was up to
b4d16ab6b3

a0a34e0a35 When an invalid muzzle flash offset is send, just return.
The original client crashed (or survived by pure luck) when muzzle
flash offsets >210 were send. Our fix was to bail out, but that broke
some buggy mods... So just return and print an optional debug message.

This fixes issue #153.

1bbd8c04ff I think that steps between 94 and 98 are wrong, remove them.
Predicting these steps leads to a heavily stuttering elevator in
hangar1. I think that steps between 94 and 98 can't appear on stairs, so
just remove them. If I'm wrong we need a hack to the hack ontop of the
hack... ^^

4d9d555d8e When vsync is enabled, cap the desired rfps.
With vsync enabled the render times of consecutive frames can diverge.
The first frame arrives right at the next display frame and is rendered
without waiting time. The next frame has to wait 20ms. The leads to some
problems with the move prediction if the client is asynchronous. Fix
this by capping the desired frame rate at the display refresh rate. Also
make sure that the network framerate is never higher then the renderer
framerate.

With the commit the timing is always correct:
* With no limit as much frames as possible are rendered. In this case
  rfps > nfps and everything's good.
* With vsync enabled rfps > nfps or rfps == nfps is given. Also rfps
  will never exceed the display refresh rate.
* On slow hardware either rfps > nfps or an implicit rfpc == nfps is
  given.

0ba7614739 Use nanosleep() instead of a busy wait loop.
This cuts the cpu time requirements in half. Windows has no equivalent

d6136cbba5 Bump cl_maxfps to 60.
Yesterday I chose setting cl_async to 0 since I saw some movement
changed with the async client enabled. Especially when clipping against
bevels the game started to stutter and there were small rendering
problems. After some debugging I realized that it is caused by slight
inaccuracies in the move prediction. When cl_maxfps is too low, the
movement error between two render frames becomes to big, leading to
misspositions. There're two ways to solve this problem:

* Processing more client frames. Most async clients I've looked on
  process 60 or even 90 render frames. I chose to stay at 60 since
  I was unable to see differences with higher rates.

* Changed to pmove.c and the pmove_t struct. Some multiplayer focused
  clients go that way. But there's a very high of breaking singleplayer
  movement and pmove_t is part of the server <-> game API. Additionally
  the network code must / should be altered. So this is unsuitable for
  YQ2.

Please note that there's still a change in movement. Before 4ae8706 and
when cl_async is set to 0 movement is dependend on the render framerate.
At low framerate bevel clipping isn't working too good, at high
framerates prediction causes physics changes like the famous 125hz bug.
With cl_async set to 1 the network framerate is stable, leading to a
more consistant behahiour.

070d94ec77 Add a cvar cl_async, off by default.
Most (all?) clients implement the synchronous and the asynchronous
client by seperate code pathes. Instead of doing that we force the
asynchronous path to process one network frame for each render frame.

a6f4a3b309 Don't predict one frame too far.
We're missusing the current frame to pass data from the input subsystem
to the movement prediction without a server frame. While we can use the
current frame for the movements itself, it's not finished and thus
unsuitable for stair step prediction. Also oldframe is determined
wrongly. As a result the player "jumps" over stairs.
