Change the PathInAfs test to use VIOCGETFID instead of VIOC_GET_CELL_NAME.
VIOCGETFID permits a literal test of the specified object. This is needed
for testing the validity of a symlink to a msdfs: or non-existent path.
Otherwise, the AFS Shell Extension context menu will not be displayed.

Change how BPlusDir enumerations behave with regards to bulk stat
operations. If the number of entries in the enumeration is larger
than the number of cm_scache objects, then using the previous model
of cm_BPlusDirEnumBulkStat being called for the entire enumeration
list results in the early objects being recycled and the status
info discarded before the caller of cm_BPlusDirNextEnumEntry()
receives the name.
The revised model triggers bulk stat operations from within
NextEnumEntry() as objects requiring status fetching are about
to be returned to the caller. This reduces the thrashing of the
stat cache.
We should consider adding a flag field to cm_BPlusDirEnumerate()
or cm_BPlusDirNextEnumEntry() to permit enumeration without
status fetching.

Unlike the unix cache manager, on Windows the server uuid was not
recorded as part of the cm_server object. This commit adds the uuid
and a flag to indicate if it is set or not.
A check is made in cm_UpdateVolumeLocation it confirm that the uuid
known to the CM is the same as the one being reported by the vl server.
If they differ, this is logged but no action is taken.
The contents of the cm_allServers list is now dumped in response to
"fs memdump" or a crash. This includes the uuid, addr, type, flags,
downtime, caps, etc.
The server uuid is not useful at the moment because there is nothing
that the CM can use it for. However, it might be useful for debugging
and it will be needed for extended callback support.

A readonly volume with multiple instances was being marked alldown
when one of the instances resulted in VNOVOL because the vldb and
the indicated file server were out of sync. The cache manager would
then attempt to re-obtain the volume location info from the vldb
for the entire timeout period.
This patch:
adds trace logging to cm_Analyze indicating which server references
are being deleted and which remain in response to a VNOVOL/VMOVED error.
adds trace logging to cm_UpdateVolumeStatusInt showing how the
new volume status value is determined.
corrects cm_Analyze() so that it doesn't corrupt the server reference
list during cm_FreeServerList() calls; doesn't orphan the server reference
list by setting *serverpp to NULL; and only re-obtains the volume info
list once per request.

Modify the cm_BPlusDirEnum interface:
* add the cm_scache_t * of the directory being enumerated to the
cm_direnum_t object
* remove the cm_scache_t * from the cm_BPlusDirEnumBulkStat call
now that it is part of the cm_direnum_t object
* maintain a reference to the cm_scache_t for the life of the
cm_direnum_t object. This ensures that the object cannot be
recycled while the enumeration is in use.

Bring a bit more sanity to the Freelance code:
1. Add functions cm_FreelanceFetchMountPointString and
cm_FreelanceFetchFileType to cm_freelance.c. These functions
permit the MountPointString and FileType to be obtained within
cm_GetSCache without requiring knowledge of data structures
that should be private to cm_freelance.c
2. Enforce the rule that odd vnode values are directory objects.
The root directory is 1 and everything else must be a multiple
of two.
3. Use the unique field as an index into the localMountPoints
array.
4. Fix cm_GetCallback to process freelance data refreshes on
all objects in the freelance volume not just the root directory.
If this is not done, an access to \\afs\foo prior to \\afs\all
being evaluated will cause an unnecessary attempt to send a
fetch status request to a file server and produce an alldown
error.
