- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.
Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

line is not printed at all. This is specified in P1003.1-2004
(SUSv3), and is useful.
* Customised headers may contain embedded space, commas and equals
signs. To specify multiple customised headers, use multiple -o or -O
options. This is specified (for "-o", not for "-O") in P1003.1-2004
(SUSv3), and is useful.
* When a column is given a null (blank) customised header, it keeps its
default minimum width. This is specified in P1003.1-2004 (SUSv3), and
seems harmless.
* Fix a bug that made it impossible to print the same keyword multiple
times, with different customised headers each time. (Previously, the
last customised header was used for all instances of the keyword.)
* Make the behaviour of "-O" more useful. The first -O option adds
the default keywords only if there have not yet been any formatting
options, and multiple -O options now insert their keywords in adjacent
positions. Now {ps -j -O %cpu} is like {ps -j} with one extra column;
Previously, it would have had all the columns implied by "-j", plus
all the default columns, plus the extra column specified by "-O".
* Convert from home-grown linked lists to SIMPLEQ lists.

- fiddle with keyword table - mainly to keep width under 80 cols
- add -k keylist so sort output
- don't use logs to work out field width, get -MAXINT right
- user defined headers can be 1 char (actually they can be zero length)
so ?? in tty column isn't guaranteed to be wider than header
- remove some long long casts (compiles on sparc64 still)
- use kvm_openfiles(NULL, NULL, NULL, KVN_NO_FILES, ..) unless core file
specified,
(approved by christos)
and in libkvm. Then teach ps how to show them to you.
Also, teach ps how to show the names for all the uids, the rest of the
group numbers, and the "group access list".
that they're 64-bit, and grab them out of memory appropriately. Otherwise,
big-endian systems get the wrong end of the 64-bit value and lose.
Keywords affected: inblk, majflt, minflt, msgrcv, msgsnd, nivcsw, nsigs,
nswap, nvcsw, and oublk.
show up as two digits, max, displaying "99" if > 99. allow any field with
an unsigned value to be specified as printing that way (though right now
it's only used for RE and SL, which are both unsigned longs). This fix
is substantially different than that suggested in the PR.
