cm_BkgPrefetch() contained two errors. First, the loop at the top of the
function that ensures that a cm_buf_t is allocated for each of the offset
positions failed to actually obtain the buffer for the specified offset.
Instead, it repeatedly obtained the buffer for the starting base address.
Second, cm_GetBuffer() would reserve all of the buffers associated with
the cm_scache_t even in the case where we already have a callback and the
existing buffer has the proper data version number. In that situation
reserving the buffers simply wastes valuable time.

Fix the lookup of cell aliases to:
1. avoid re-reading CellServDB each time a cell alias is specified
2. avoid reconstructing the vlserver list for the cell each time an
alias is specified
3. permit aliases to be used when AFSDB records were used previously
with the full cell name

Reduce the default number of background daemon threads used for prefetch and
store operations to one. Given the current implementation when more than
one thread is allocated they step on each other's toe while fighting over
locks.
A better model might be to divide up threads based upon cells or volumes
as a means of preventing contention.

The case of openafs.org and grand.central.org is a hideous abuse of
the AFS cell name space. There are many negatives associated with
trying to support two different cell names pointing at overlapping
vlserver lists:
(1) The CM can store duplicate entries for all of the data simply because
the cell name that was used is different
(2) If the CM attempts to optimize the data storage by aliasing or otherwise
combining the cell names as part of one cm_cell_t object, then future
attempts to separate the two cell names will require the destruction
of the cache.
(3) If the CM does not associate a callback revoke with a particular cell,
then the status data associated with any entry that matches the revoked
AFSFid will be discarded. For volume callbacks this can have a serious
impact because volume IDs are not unique across cells and discarding
status data for readonly volumes that are in use can result in a
significant number of FetchStatus requests being sent to the associated
file server.
There are other issues as well involving authentication.
The case of openafs.org advertising the vlserver addresses of
grand.central.org should be considered a hack; a hack that the Windows
client will no longer ensure will work.
Additional debugging messages have been added to assist individuals attempting
to debug why callback revokes do not appear to take affect when two cell
names share the same vlserver data.

The pthread_cond_timedwait/wait implementations were broken. Not only

Update event_handler() for Windows. The return code of
pthread_cond_timedwait() is not limited to 0 and -1 because 'errno'
cannot be set. Instead of setting 'errno' the error code is returned
directly by the function as the return code.
This patch is only for debugging purposes to track the number of
success, timeout, and other errors experienced by the routine.

Remove the callback revoke optimization that prevents a (vol,vn,uniq)

determine the cell from the server because the server might be identified

grand.central.org.

This patch completes the implementation of smb_ReceiveTran2GetDFSReferral()
which is called by Vista even if we do not advertise the support of DFS
referrals. It also adds DFS link mapping notifications to the volstat
interface which can be used by volstat plug-ins to redirect requests to
the dfs target path.
Other miscellaneous items:
(1) return EAS_NOT_SUPPORTED instead of EA length 0 and silently accepting
but not storing EA data
(2) Call cm_VolStatus_Service_Started() before smb initialization instead
of afterwards
(3) During directory enumeration and link assembly push the UNC path into
the lower levels by storing references to the tidPath and the relative
paths within the cm_req_t object.
(4) During directory enumeration make absolutely sure that we do not
reference an unallocated cm_dirEntry_t object
(5) publish a prototype for cm_FollowMountPoint()
(6) return ERROR_RETRY instead of BAD_NETWORK_PATH if the server returns
VBUSY
(7) return PATH_NOT_COVERED instead of BADSHARENAME for DfsLinks when
a volstat plugin is in use
