Attempts to open files which are already write-locked by another
client took forever to return a lock not granted error.  This 
was because cm_Analyze() would retry the lock request for up to
the RDRtimeout in response to the EAGAIN error.  The problem 
was that cm_IntSetLock() was not setting the CM_REQ_NORETRY flag.

While examining this issue, discovered two other things:

(1) the infinite wait logic on lock request processing was broken
(2) the cancel outstanding lock request logic wasn't implemented
(3) cm_Analyze() would put the thread to sleep even when retries
    were not permitted.

Also removed a number of compile time warnings.
