Add a debug log warning if the target volume is a DFS File Set.
If so, the client will not properly protect against information
leakage or properly deal with directory name caching, symlinks,
and other behavioral differences between AFS and DFS.

Fix issue reported by Marc Dionne. RXAFS_FetchData and RXAFS_StoreData
return access denied errors that are not reported by the subsequent
call to rx_EndCall which should be preferred.

cm_Link() is used to create hard links. It did not apply the updated
link target status info to the target cm_scache_t object. As a result
the linkCount would be incorrect.
cm_Unlink() did not take linkCount into account. It did not reduce the
locally known linkCount, nor did it invalidate any currently known
callback. As a result the linkCount would be incorrect.

Properly handle callbacks from multi-homed file servers.
Comparing cm_server_t pointers is insufficient. For a multi-homed
server there will be multiple entries. The UUID for all of the
equivalent entries will be the same. What matters is not that
the pointers are the same but whether in the case of UUID labeled
servers that the UUIDs match.
Add cm_ServerEqual() to perform the comparison.

Readonly volume callbacks apply to every cm_scache_t from the
same volume. We were already tracking the cbExpires time in
the cm_volume_t. We need to also track the cbServerp in the
cm_volume_t so that the cm_scache_t objects can be assigned
the correct server from which the callback was issued.
Add cbServerpRO field to the cm_volume_t. Bump the memory
map version to force a rebuild of the cache data.

1. Add a test program for *printf functionality. util/tests/snprintf_test.c
2. Replace OpenAFS implementation of afs_*printf() with Heimdal's version.
3. Add support to Heimdal's version to support:
- floating point
- OpenAFS %I ipv4 address formatting (dotted notation and hostname lookup)
- Microsoft's I32 and I64 integer size modifiers
With these changes OpenAFS gains:
- output that is compliant with standard *printf implementations.
the previous implementation had justification, padding and case
errors.
- support for a NULL buffer which computes the required size based
upon the input format and arguments. the previous implementation
would crash.
- support for additional format types.
- OpenAFS specific implementations of vasnprintf(), vasprintf(),
asprintf(), and asnprintf().

The CellServDB processing in auth/cellconfig and WINNT/afsd/cm_config
differ in one important way. cellconfig uses the IP addresses specified
in the CellServDB file and ignores the host name; whereas cm_config
calls gethostbyname() on the host name and falls back to the specified
address only if gethostbyname() fails.
This commit modifies cellconfig to use gethostbyname() calls on the
host names when the client CellServDB file is being used. The server
CellServDB file is left alone because ubik servers need to be given
the exact list of ip addresses specified by the administrator and
there is no method of indicating clones to other servers using DNS.
This change permits a greater resilency to cell server configuration
changes due to IP address renumbering as the DNS names in the CellServDB
file can be CNAME or A records.
A host name can be resolved to multiple IP addresses and all of the
addresses will be added to the hostAddr list for the cell provided
that they do not exceed the maximum number of hosts. If the same
host name is listed multiple times the duplicate IP addresses will
be ignored.
The behavior of all tools that use CellServDB files on Windows will now
be consistent.

When processing RX_CALL_TIMEOUT, if there is no fid specified its a vldb
rpc and we should retry. If there is a fid and the volume is a readonly
volume then we should also retry. Only fail if the request has no alternate
server to look at.
When processing RX_CALL_DEAD, log the fact that the call is dead.
When processing any other RX error between -2 and -64, do not force
a new connection to the same server. Mark the server down and retry
with a new server if possible.

When inserting a new vldb server, if the rank is 0 (unknown), do not

Turn SRXAFSCB_InitCallBackState3() into the primary function for
processing InitCallBackStateX RPCs. InitCallBackState3 accepts an
optional server uuid which can be used instead of the IP address
to locate a matching server object. If the RPC comes from a server
that we know of, we can restrict the calback state initialization
to cm_scache_t objects on that file server. If the request comes
from a server that we know nothing about and a uuid was specified,
we can ignore it.
During callback revocation, make use of the cell associated with
the server to restrict the revocation to cm_scache_t objects in
the one cell. This is especially important for readonly volume
callbacks since volume ids are shared across multiple cells.
Add a missing case where the cm_volume_t cbExpiresRO time should
be set to the cm_scache_t cbExpires time.

cm_cellLock protects the cm_cell_t fields allNextp, nameNextp, idNextp,
and freeNextp. Therefore, a write lock must be obtained whenever those
items may change. This patch makes that consistent.
This patch also fixes an out of order lock acquisition and removes
cm_cell_t objects from the id and name hash tables before freeing them.
