1. Change RxEnableHotThread default to 'on'

2. Add a 'hash' value to the cm_fid_t structure in order to speed up cm_FidCmp().
   Add cm_SetFid() for use in constructing a fid complete with the hash.

3. Redefine the BUF_HASH and BUF_FILEHASH in terms of the cm_fid_t hash which
   has a better distribution

4. Modify cm_ConsiderPrefetch to evaluate the amount of data in the most recent
   read request instead of the next chunkSize.  cm_chunkSize can be dozens or
   hundreds of buffers.  As a result too much time is spent performing the
   evaluation.

5. Fix the usage of cm_scache_t bufCreateLock.  The purpose of this lock is
   to prevent the creation of new buffers while a truncation is being performed.
   All references to bufCreateLock have been removed except in two places:
   i.  a write-lock surrounding the function that calls buf_Truncate()
   ii. a read-lock within buf_GetNewLocked() that actually allocates new
       buffers

6. Modify the CM_CONFIG_DATA_MAGIC value to include a CM_CONFIG_DATA_VERSION
   number which value be used to force the replacement of the cache file
   contents when incompatible changes are made between releases.

7. CM_SCACHESYNC_ASYNCSTORE should not be ordered by cm_SyncOpCheckContinue

8. Avoid calls to multi_Rx if nconns == 0

9. Modify smb_WriteData to perform background writes based upon the crossing
   of buf_blockSize boundaries instead of cm_chunkSize boundaries.  This will
   slow down writes from the SMB interface but will avoid the risk of
   the CIFS client disconnecting from the AFS client SMB server.
