Change subject: Fix deadlock handling subscribe req during res_parking reload
......................................................................


Patch Set 4:

I've re-written the patch. The new one just uses a different stasis message type, i.e. hint_remove_message_type, in order to clarify the execution flow.

IMHO even w/o my patch the flow of that part of code is not so linear. 


Furthermore by looking at the code I'm quite sure that the call to handle_hint_change_message_type(msg, AST_HINT_UPDATE_PRESENCE) added in commit 1600ebca7d9 is not executed anymore since commit d748ed4147f, but that's a different issue.
