MFV r302260: expat 2.2.0

Approved by: re (kib)

Improve collation string and locales support

Merge collation support from Illumos and DragonflyBSD.

Locales are now generated with the new localedef(1) tool from CLDR POSIX files.
The generated files are now identified as "BSD 1.0" format.

The libc now only read "BSD 1.0" locales definitions, all other version will be
set to "C"
The localedef(1) tool has been imported from Illumos and modified to use tree(3)
instead of the CDDL avl(3)
A set of tool created by edwin@ and extended by marino@ for dragonfly has been
added to be able to generate locales and the Makefiles from the vanilla CLDR
unicode databases + a universal UTF-8 charmap (by marino@)
Update the locales to unicode v27
Given our regex(3) does not support multibyte (yet) it has been forced to always
use locale C
Remove now unused colldef(1) and mklocale(1)
Finish implementing the numeric BSD extension for ctypes
The number of supported locales has grown from 175 to 250 locales. Among the new
locales: 6 Arabic locales (AE EG JO MA QA SA), Different variations of spanish
locales.
Added new 3 components locales for mn_Cyrl_MN, sr_Cyrl_RS sr_Latn_RS,
zh_Hans_CN, zh_Hant_HK and zh_Hant_TW. Some aliases has been for 2 components
version when possible.

Thanks: Garrett D'Amore (Illumos) who made sure all his work was done under
BSD license!, Edwin Groothuis (edwin@) for the work he made on tools to be able
to generate locales definition usable in freebsd sources out of vanilla CLDR
definitions, John Marino (DragonflyBSD) who first merge the Illumos work into
Dragonfly and spent hours tracking down bugs.

Merge mpsutil(8) branch

mpsutil(8)/mprutil(8) are new utilities for managing LSI Fusion-MPT
2/3 controllers (mps(4) and mpr(4))

For now only informational commands have been implemented.

This utility has been written by scottl@ [1] and polished by myself[2]

With retirement of cpumask_t and usage of cpuset_t for representing a
mask of CPUs, pc_other_cpus and pc_cpumask become highly inefficient.

Remove them and replace their usage with custom pc_cpuid magic (as,
atm, pc_cpumask can be easilly represented by (1 << pc_cpuid) and
pc_other_cpus by (all_cpus & ~(1 << pc_cpuid))).

This change is not targeted for MFC because of struct pcpu members
removal and dependency by cpumask_t retirement.

MD review by: marcel, marius, alc
Tested by: pluknet
MD testing by: marcel, marius, gonzo, andreast

etire the cpumask_t type and replace it with cpuset_t usage.

This is intended to fix the bug where cpu mask objects are
capped to 32. MAXCPU, then, can now arbitrarely bumped to whatever
value. Anyway, as long as several structures in the kernel are
statically allocated and sized as MAXCPU, it is suggested to keep it
as low as possible for the time being.

Technical notes on this commit itself:
- More functions to handle with cpuset_t objects are introduced.
The most notable are cpusetobj_ffs() (which calculates a ffs(3)
for a cpuset_t object), cpusetobj_strprint() (which prepares a string
representing a cpuset_t object) and cpusetobj_strscan() (which
creates a valid cpuset_t starting from a string representation).
- pc_cpumask and pc_other_cpus are target to be removed soon.
With the moving from cpumask_t to cpuset_t they are now inefficient
and not really useful. Anyway, for the time being, please note that
access to pcpu datas is protected by sched_pin() in order to avoid
migrating the CPU while reading more than one (possible) word
- Please note that size of cpuset_t objects may differ between kernel
and userland. While this is not directly related to the patch itself,
it is good to understand that concept and possibly use the patch
as a reference on how to deal with cpuset_t objects in userland, when
accessing kernland members.
- KTR_CPUMASK is changed and now is represented through a string, to be
set as the example reported in NOTES.

Please additively note that no MAXCPU is bumped in this patch, but
private testing has been done until to MAXCPU=128 on a real 8x8x2(htt)
machine (amd64).

Please note that the FreeBSD version is not yet bumped because of
the upcoming pcpu changes. However, note that this patch is not
targeted for MFC.

People to thank for the time spent on this patch:
- sbruno, pluknet and Nicholas Esborn (nick AT desert DOT net) tested
several revision of the patches and really helped in improving
stability of this work.
- marius fixed several bugs in the sparc64 implementation and reviewed
patches related to ktr.
- jeff and jhb discussed the basic approach followed.
- kib and marcel made targeted review on some specific part of the
patch.
- marius, art, nwhitehorn and andreast reviewed MD specific part of
the patch.
- marius, andreast, gonzo, nwhitehorn and jceel tested MD specific
implementations of the patch.
- Other people have made contributions on other patches that have been
already committed and have been listed separately.

Companies that should be mentioned for having participated at several
degrees:
- Yahoo! for having offered the machines used for testing on big
count of CPUs.
- The FreeBSD Foundation for having sponsored my devsummit attendance,
which has been instrumental.
- Sandvine for having offered offices and infrastructure during
development.

(I really hope I didn't forget anyone, if it happened I apologize in
advance).

Merger of the quota64 project into head.

This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).

By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:

options QUOTA # Enable FFS quotas

If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.

There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.

Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.
