mpsvar.h: Bump the number of chain frames from 1024 to 2048. From
testing, it looks like this makes it less likely that we'll
run out of chain frames, and it doesn't cost much memory
(32K).

As it was pointed out by Alan Cox, that no longer serves its purpose with
the modern UMA allocator compared to the old one used in 4.x days.
The removal of sysctl eliminates max_proc_mmap type overflow leading to
the broken mmap(2) seen with large amount of physical memory on arches
with factually unbound KVA space (such as amd64). It was found that
slightly less than 256GB of physmem was enough to trigger the overflow.

different processes that happen to use the same user address in the
separate processes will now be treated as distinct futexes rather than the
same futex. We can now honor shared futexes properly by mapping them to a
PROCESS_SHARED umtx_key. Private futexes use THREAD_SHARED umtx_key
objects.

file's last accessed, modified, and changed times:
TMPFS_NODE_ACCESSED and TMPFS_NODE_CHANGED should be set unconditionally
in tmpfs_remove() without regard to the number of hard links to the file.
Otherwise, after the last directory entry for a file has been removed, a
process that still has the file open could read stale values for the last
accessed and changed times with fstat(2).
Similarly, tmpfs_close() should update the time-related fields even if all
directory entries for a file have been removed. In this case, the effect
is that the time-related fields will have values that are later than
expected. They will correspond to the time at which fstat(2) is called.

returns the ctsduration, or -1 for HT rates;
* add a printf() to ath_tx_calc_ctsduration() which will be
very loud if somehow that function is called with an MCS
rate;
* Add ath_tx_get_rtscts_rate() which returns the RTS/CTS
rate to use for the given data rate, incl. the short
preamble flag;

It's used to calculate:
* the initial per-rate entries for short/long preamble ACK durations;
* packet durations for TDMA slot decisions;
* RTS/CTS protection durations;
* updating the duration field in the 802.11 frame header
This way invalid durations will generate a warning, prompting for it to be
fixed.
The current code transmits management and multicast frames at MCS 0.
What it should do is check whether the negotiated basic set is zero (and
the MCS set is not) before making this decision.
For now, simply default to the lowest negotiated rate, rather than
MCS 0. This fixes the behaviour with at least the DLINK DIR-825, which
ACKs but silently ignores block-ack (BA) response frames.
