There is code that tried to deep-copy `salt.fileclient.RemoteClient` and
fails. The callstack below shows this occurring.
This change makes `RemoteClient` picklable so that it may be deep copied.
It requires this because its constructor requires an `opt` parameter.
The error looks like this:
[ERROR ] Exception in callback (1260L, <function wrapped at 0x0000000007434828
>)

salt/utils/process.py:
- Since `log_queue` is now passed in explicitly, it now may exist with a
value of `None`. `MultiprocessingProcess.__init__` has been modified to
handle this case.
