Just relying on status LE ownership of status block seems to cause
poor performance. Always read current status index register first
and then check status ownership as we had before. Accessing status
index register seems to trigger immediate status update if
controller have pending status updates.

This framework allows drivers to abstract the rate control algorithm and
just feed the framework with the usable parameters. The rate control
framework will now deal with passing the parameters to the selected
algorithm. Right now we have AMRR (the default) and RSSADAPT but there's
no way to select one with ifconfig, yet.
The objective is to have more rate control algorithms in the net80211
stack so all drivers[0] can use it. Ideally, we'll have the well-known
sample rate control algorithm in the net80211 at some point so all
drivers can use it (not just ath).
[0] all drivers that do rate control in software, that is.

killed by OOM. When killed process waits for a page allocation, try to
satisfy the request as fast as possible.
This removes the often encountered deadlock, where OOM continously
selects the same victim process, that sleeps uninterruptibly waiting
for a page. The killed process may still sleep if page cannot be
obtained immediately, but testing has shown that system has much
higher chance to survive in OOM situation with the patch.

still exists as a zombie. The 'kill -0' test in this function can
therefore return true even if the process isn't actually running.
This could lead to wait_for_pids() printing an endless string of the
pid number until the zombie finally exits.
Solve this problem by moving the sleep up to after the 'kill -0' test, but
only after we've run through the function once already. In the common case
(only one pid in the list) this will always do the right thing. On the rare
occasion that there is more than one pid in the list this will sleep 1
second per zombie process which will allow that process, and any other
in the list a chance to exit.
While I'm here, local'ize the variables that this function uses.
checks on the length of the client's open/lock owner name. Also,
add free()'s for one case where they were missing and would
have caused a leak if NFSERR_BADXDR had been replied. Probably
never happens, but the leak is now plugged, just in case.

coda.h:
- CodaFid typdef -> struct CodaFid throughout.
- Use unsigned int instead of unsigned long for venus_dirent and other
cosmetic fixes.
- Introduce cuid_t and cgid_t and use instead of uid_t and gid_t in RPCs.
- Synchronize comments and macros.
- Use u_int32_t instead of unsigned long for coda_out_hdr.
With these changes, a 64-bit Coda kernel module now works with
coda6_client, whereas previous userspace and kernel versions of RPCs
differed sufficiently to prevent using the file system. This has been
verified only with casual testing, but /coda is now usable for at least
basic operations on amd64.

This makes sh a bit more friendly in single user mode, make buildenv, chroot
and the like, and matches other shells.
The -o emacs can be overridden on the command line or in the ENV file.
This fix mostly matters after r206129 that made it possible for
st_blksize to be greater than 4K. For this reason, this change should
be MFC-ed before r206129.
Also, it seems that all FreeBSD uitlities that use db(3) hash databases
and create new databases in files, specify their own block size value
and thus do not depend on block size autotuning.

For the negative case, set it to the maximum allowable, since it
was actually a large positive value (unsigned) on the wire.
Also, fix up the readdir function comment a bit.
