db_flatstore: Fix missing CDRs due to 'flat_rotate' race conditions
This commit simply adds R/W locking around the 'flat_rotate' MI command,
and all the SIP worker processes. The race condition was as follows:
* SIP worker checks the 'flat_rotate' stamp and proceeds to write CDR
* 'flat_rotate' is ran (timestamp++)
* external process scans & fully reads the rotated file (with deletion
to follow later as well, but this is irrelevant)
* SIP worker finally writes the CDR using flushed/vector'ed I/O
(too late at this point, CDR is forever lost)
