The rx_pthread.h defines afs_kcondvar_t and afs_kmutex_t but
their use throughout the rx library is inconsistent. Sometimes
they are used, other times pthread_cond_t and pthread_mutex_t.
This commit ensures that afs_kmutex_t and afs_kcondvar_t are
used consistently.

Permit the rx library to be built without the RXDEBUG preprocessor
definition. When RXDEBUG is not defined all of the debugging functions
either become stubs or log a message indicating that the library was
built without RXDEBUG so that there will be no surprises. There
are no changes to the export list. By default RXDEBUG is defined.
Eventually the definition of RXDEBUG can become a configuration option
to the build system.

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.

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.

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.

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.

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)
