The most substantial memory leak came from `PacketQueue::get`
not unreferencing its argument packet.
Other leaks came from using `av_free` instead of type-specific free
functions.
Also modifies `PacketQueue::put` for readability.
When a position is forced, the actor position in physics subsystem is
overriden. The background physics thread is not made aware of this,
its result are simply discarded.
There is a short window where this doesn't work (in this
example, actor is at A and script moves it to B)
1) actor position is set to B. (among others, Actor::mPosition is set to B)
2) physics thread reset Actor::mPosition with stale value (around A)
3) main thread read simulation result, reset Actor::mSkipSimulation flag => actor is at B
4) physics thread fetch latest Actor::mPosition value, which is around A
5) main thread read simulation result, actor is around A
To avoid this situation, do not perform 2) until after 3) occurs. This
way, at 4) starts the simulation with up-to-date Actor::mPosition
Restore projectile caster from savegame (#5860)

This enables accelleration of heightfield collisions.
Unfortunately, `btHeightfieldTerrainShape::processAllTriangle` does not
yet use the accellerator data, so this change does not improve
performance yet but might do so in future bullet versions.

`$<TARGET_FILE:...>` fails if the argument is already a path (instead of
a library name). This happens when a static library is found via
`osg_find_library`.
If the argument contains `/` or `.`, do not use `$<TARGET_FILE:...>`
Measure time at the computation end but before sleep. This allows to adjust
sleep interval for the next frame in case sleep is not precise due to syscall
overhead or too low timer resolution.
Remove old frame limiting mechanism.
projectile collision shape.
A side effect of moving actors outside of projectile collision shape is that if both the actor and the projectile are
near a wall, the actor could get moved outside of the world.
