This didn't work correctly for multiple reasons:
1. `deltayaw` was wrongly initialized for the pusher itself, rather than
for pushed client.
2. `delta_angles[YAW]` is a short, adding plain `amove[YAW]` to it is
wrong.
To support yaw angle rotation properly, delta_angles must be
interpolated on the client. But this is hardly practical as it would
introduce other bugs. Thus, simply remove delta yaw manipulation code
altogether.
Fixes infamous Q2 bug when player standing on a blocked lift gets turned
to wrong direction.
This ensures that we call ARM64 `aarch64` on all platform, which aren't
MacOS or Windows. And it fixes the bug, that `arm64` was normalized to
`arm`, making incompatible savegames between 32 bit and 64 bit ARM
loadable. Leading to crashes.
The problem in door_go_up() may prevent doors from crushing something
blocking them. The problem in G_UseTargets() may prevent targets from
getting killed or fired.

The ThrowHead() and ThrowClientHead() functions are special. They
transform the entity given in `self` (mostly the caller itself) into a
ripped off head. They don't reset the entities clip mask, which may
cause problems in interactions with other entities. Fix that by reseting
the clip mask to `MASK_SHOT`.

There were complains that always generating footsteps is annoying,
because there will be footsteps while swimming or jumping. Refine
the cvar a little bit:
* `0`: No footsteps at all.
* `1`: Vanilla Quake II behavior.
* `2`: Always footsteps as long as the player has a ground entity.
* `3`: Always footsteps.
The changes the meaning of the values, `2` has become `3`.

I added the CMakeLists.txt 6 or 7 years ago so I could load the code
into Jetbrains Clion. I have moved to another editor years ago and the
cmake stuff is effectively unmaintained since then. We kept it around
in case that we'll do a MSVC port, but that's unlikely at this point.
Since bugreport and problems with the CMakeLists.txt keep coming up,
finally retire them. They can be resurrected from the git history if
we'll ever need them again.
Part of yquake2/yquake2#725.
1: The Vanilla Quake II behaviour, footsteps are generated when the
player is faster than 255.
0: Footstep sounds are never generated.
2: Footstep sounds are always generated.
Defaults to `1`
