Speed up linux ocserver to fix apparent instabilities.
The linux ocserver had three threads running uncluding the main thread.
All three had sleeps in it and there was a delay of 2 seconds between
every call to OCProcess ().
This caused the ocserver to be slow and the server appeared to be
unstable specially when there were many clients sending in requests to
one server.
- Changed ocserver to start the observation thread only when observation
is requested similar to the C++ sample simpleserver.
- Removed the sleep between calls to OCProcess ()
- Moved stopping presence logic to the presence thread from the
observation thread.
This may be cherrypicked to 1.0.0-dev.
