Permit rx statistics gathering to be disabled by setting the
new rx_stats_active variable to 0. This avoids grabbing the
rx_stats_mutex throughout the execution of the requests and
permits greater concurrency thoughout the library.
LICENSE MIT
not everything should be under the rx_stats_mutex. doing so
results in too much lock contention. add new mutexes:
rx_quota_mutex, rx_waiting_mutex, rx_pthread_mutex, and rx_packets_mutex.
Each new mutex protects an associated group of variables.

if the socket buffer size specified by the configuration is too large
to be applied, do not drop down immediately to 32766 bytes. Instead
try increasingly smaller values trying to find the largest one that
works. use the same value for the send buf size as well.
LICENSE MIT
Throughout rx_rdwr.c functions allocate a register variable 'cp'
which is used to optimize access to call->currentPacket.
Unfortunately, if the call->lock is dropped (for example, CV_WAIT)
the synchronization between the two is lost. This delta re-syncs
'cp' and call->currentPacket after each location where the call->lock
may be dropped.
LICENSE MIT
Ensure that the input string is nul terminated and then instruct
WideCharToMultiByte to compute the length itself instead of passing
in a value that is very likely to be wrong.

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.

reverse change from 20081226. removing the auto-generated manifest
removes the manifest binding to the run time library. The reason
two manifests are specified is that we are merging them.

Validating the state of the rx library is hard. This patch makes it
a bit easier to validate from within crash dumps (or on Windows in
"fs memdump" output) whether rx packets and calls are in a sane state.
When the library is compiled with -DDEBUG the rx_call and rx_packet
data structures are extended to include a linked list of all allocated
objects and counters are added to track the number of packets on each
of the transmit, receive, and iovec queues.
This compliments the tracking of packet states via RX_PKTFLAGs.
For Windows, rx_DumpCalls and rx_DumpPackets functions are added
that will dump the state of all allocated calls and packets (in Checked
build) in response to a "fs memdump" command. These functions are
exported from afsrpc.dll.

FIXES 124072
adds ATTR_* constants for UKERNEL code, and makes use
of them. Without this in some cases updating file metadata will also
update unrelated metadata (e.g. truncating a file changes the mode
bits).
adds threadsafe positional i/o calls to
afs_usrops.c: uafs_pwrite and uafs_pread, allowing for threadsafe
libuafs i/o.
changes the types of some fs-related
variables to be more "correct", I think (off_t for offsets, mode_t for
file mode, etc), it fixes a bug where nDaemons is not correctly set from
the uafs_Init parameter, fixes a segfault in uafs_open when O_CREAT is
specified, initializes a couple of static vars, "#if 0"s out code that
copies tokens from kernel-space to user-space (doesn't seem to work from
what I've seen, and the current code crashes on clientless Solaris
machines from being killed by SIGSYS)

when performing a lookup operation it is acceptable for the data version
of the btree to be greater than the data version of the cm_dirOp_t
under which the operation is being performed. No change to the btree
can take place and the result of the lookup will maintain consistency
without requiring an additional restart of the directory operation.
LICENSE MIT
when prefetching the directory buffers do not call cm_FlushFile to
discard locally modified buffers. Instead just set the cm_scache_t
bufDataVersionLow to the current version. out of date buffers will
therefore be ignored without requiring that locks be dropped and
reacquired and without searching all of the buffers associated with
the directory.
LICENSE MIT
Do not permit cm_Rename() to rename an existing object such that it
creates a case-insensitive name collision with another object.
This change in behavior is consistent with the restrictions when
creating new objects. This change prevents the explorer shell from
getting confused when it creates a new folder.
