Popping objects from the buffer is still not implemented.

Service code now doesn't have to deal with this.

IPC: Use the correct size when pushing raw data to the command buffer and fixed pushing domain objects.

Domain object ids are always stored immediately after the raw data.

Missed this in my first implementation. Thanks to @wwylele for pointing
out that this was missing.

Reduces the necessary allocation to max(in_handles, out_handles) rather
than (in_handles + out_handles).
