d6464ce40d add 'replay' command log feature: no mouse interaction during replay, and use a fixed number of sim steps in stepSimulation.
workaround for reversed separating normal in gjk/epa when using very small shapes, detect case and revert normal.
use smaller world size (10 units versus 100) for higher resolution shadow map
use a hard-coded rolling friction of 0.2 for objects in physics server (will make this configurable)
fix loading of command log files, when platform features are different (64bit/32bit)

=
003a42478b another step closer to useable shared memory C API
(force/torque sensor needs new API)
in a nutshell, users of shared memory physics API should not
directly poke into shared memory, not fill 'SharedMemorCommand'
nor read SharedMemoryStatus directly. The C-API declares 'handles' for those,
to avoid it from happening.

4cbd86a058 Detach posix shared memory correctly
* shmget() fails after shmctl() is called with IPC_RMID. This patch
removes shmget() in releaseSharedMemory so that a client can detach
a shared memory correctly after a server removed it.
* A server should also detach a shared memory.

transmit the serialized btMultiBody data back from server to client, after the server loads a URDF file. This includes base+link+joint names
tweak the serialization routines, so it is easier to skip pointers and to serialize directly to a shared memory buffer
also tweak the serialization code to allow to process data without 'DNA' schema data (assuming file-DNA = memory DNA)
