make PhysicsClient an interface class, and move shared memory implementation
...
of physics client into PhysicsClientSharedMemory class/file.
This will allow implementation of UDP and other transport protocols to a physics server.

improvements to the shared memory physics API:
...
support picking in C API etc.

=
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.

initial implementation to send debug lines from physics server to client,
...
need to add streaming because memory is too small to store all lines
initial test of PD control in physics server, need to switch to PD control for motor constraint, instead of using external forces.

add command-line argument for example browser and shared memory app, --shared_memory_key=<int>

fix some shared memory issues, client uses attach/detach, server uses create/remove shared memory
implement CMD_RESET_SIMULATION

fixes in shared memory:
...
only allow server to create and initialize shared memory,
client will report failure
intercept signals to cleanup shared memory in standalone app, thanks to
Roland Philippsen.

fix shadowmap crash on some Intel GPUs, see https://github.com/bulletphysics/bullet3/issues/4
...
remove targetdir from all libraries in premake, so it is much easier to create a separate folder for all binary+lib
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)
