When message events were added, the debug field name was overlooked. This would have only been hit when debug level was above 'DEBUG1' and at that point it would have incorrectly chosen debug display names.

This was writing a null one space to the right, outside of the malloc'd buffer. On further review this uses apr_vsnprintf which always returns null terminated.

Since there isn't neutral ground, on the rtmp state callback we actually have to force the write lock of the session, but we only need a try lock on removing the session from the rsession->session_hash. This removes a deadlock caused when we had to enforce with locks that the rsession couldn't be destroyed if the FS session was in the middle of a hangup.

Seems having a read lock still prevents a write lock to be taken, even if the thread that is trying to get the write lock currently has the read lock.
