An implementation of Asanka's idea.
Avoid the need to update the data version number on each buffer associated
with a scache when MergeStatus is called after a StoreData by maintaining
a range of valid data versions as part of the cm_scache_t object.

Improve parallelism by using InterlockedIncrement and InterlockedDecrement
to adjust the refCount fields of cm_buf_t and cm_scache_t objects. This
permits read locks to be used for increments and decrements but requires
a write-lock to perform any actions based upon the refCount hitting zero.
Inline cm_FidCmp to further improve performance.
Remove unused variables.

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.

my code, though, this is a result of a problem reported by Chaskiel Grundman and analysis by him, Jeff Altman and myself.
I'm just checking in my implementation. In any case, the issue this addresses
is one where we can end up in makecall_waiting in rx on multiple connections
when we multibreakcallback because the lists are sorted differently and each has "pending" calls on a different connection. by sorting by index we will not
block on another caller while also holding what they're after

The RXKADBADTICKET error is returned when a krb5 derived token is sent
to a server that does not support them. In a mixed cell it is possible
that some servers were not updated. Discarding the token does not make
it possible to perform the request successfully and adversely affects
the user experience because those servers that do support the token
can no longer be accessed in an authenticated manner. Users can't
determine what the cause is, all they see are their tokens disappearing
and there is nothing they can do about it anyway.
From now on return STATUS_NO_KERB_KEY and do not retry.
