This will enable the elimination of a workaround in the USB driver that
artifically allocates buffers twice as big as they need to be (which
actually saves memory for very small buffers on the buggy platforms).
When deciding how to allocate a dma buffer, armv4, armv6, mips, and
x86/iommu all correctly check for the tag alignment <= maxsize as enabling
simple uma/malloc based allocation. Powerpc, sparc64, x86/bounce, and
arm64/bounce were all checking for alignment < maxsize; on those platforms
when alignment was equal to the max size it would fall back to page-based
allocators even for very small buffers.
This change makes all platforms use the <= check. It should be noted that
on all platforms other than arm[v6] and mips, this check is relying on
undocumented behavior in malloc(9) that if you allocate a block of a given
size it will be aligned to the next larger power-of-2 boundary. There is
nothing in the malloc(9) man page that makes that explicit promise (but the
busdma code has been relying on this behavior all along so I guess it works).
Arm and mips code uses the allocator in kern/subr_busdma_buffalloc.c, which
does explicitly implement this promise about size and alignment. Other
platforms probably should switch to the aligned allocator.
In retrospect, having an alias for UTF-8 does not bring any real benefits
and it can cause confusion. Let's remove this *.UTF8 locale symlinks
which is closer to the convention of the other BSDs.
GCC testsuite is also removing utf8 and UTF8 locales for portability
with BSD.

In the old days, device drivers passed NULL for the parent tag when creating
a new tag, and on arm platforms that resulted in a global tag representing
overall platform constraints being substituted in the busdma code. Now all
drivers use bus_get_dma_tag() and if there is a need to represent overall
platform constraints they will be inherited from a tag supplied by nexus or
some bus driver in the hierarchy.
The only arm platforms still relying on the old global-tag scheme were some
xscale boards with special PCI-bus constraints. This change provides those
constraints through a tag supplied by the xscale PCI bus driver, and
eliminates the few remaining references to the old global var.

Previous code supported only "continuous" code without any kind of
branch instructions. To change that, new function was implemented
which parses current instruction and returns an addres where
the jump might happen (alternative addr).
mdthread structure was extended to support two breakpoints
(one directly below current instruction and the second placed
at the alternative location).
One of them must trigger regardless the instruction has or has not been
executed due to condition field.
Upon cleanup, both software breakpoints are removed.
This implementation parses only the most common instructions
that are present in the code (like 99.99% of all), but there
is a chance there are some left, not covered by the parsing routine.
Parsing is done only for 32-bit instruction, no Thumb nor Thumb-2
support is provided.

I discovered that we're logging each trap, which gets pretty spendy;
and there wasn't any further information on the pid/tid/progname involved.
I originally noticed this because I don't attach anything to /dev/log and so
the log() output stays going to the kernel. That's an oops on my part, but
I'm glad I did it.
This commit adds the following:
* a rate limiter, which could do with some eyeballs/ideas on how to
make it more predictable on SMP;
* log pid, tid, progname (comm) as part of the output.
I now get output like this:
Unaligned Load Word: pid=621 (pmcstat), tid=100060, pc=0xffffffff803ae898, badvaddr=0x40a10055
Unaligned Load Word: pid=621 (pmcstat), tid=100060, pc=0xffffffff803ae898, badvaddr=0x40a10051

Unaligned Load Word: pid=602 (login), tid=100042, pc=0xffffffff803ae898, badvaddr=0x401151
.. which makes it much easier to start figuring out what/where to fix.
The pc looks suss (it looks like it's in kernel space); I'll dig into that one next.

Sorting eucJP text with "sort" resulted in an illegal sequence while
"gsort" worked. This was traced back to mbrtowc handling which was
broken for eucJP (probably eucCN, eucKR, and eucTW as well). This
small fix took hours to figure out. The OR operation to build the
wide character requires an unsigned character to work correctly. The
euc wcrtowc conversion is probably broken upstream in Illumos as well.

The output of "locale charmap" is identical to the result of
nl_langinfo (CODESET) for any given locale. The logic for returning the
codeset was very simplistic. It just returned portion of the locale name
after the period (e.g. en_FR.ISO8859-1 returned "ISO8859-1").
When softlinks were added to locales, this broke. e.g.:
en_US returned ""
en_FR.UTF8 returned "UTF8"
en_FR.UTF-8 returned "UTF-8"
zh_Hant_HK.Big5HKSCS returned "Big5HKSCS"
zh_Hant_TW.Big5 returned "Big5"
es_ES@euro returned ""
In order to fix this properly, the named locale cannot be used to
determine the encoding. This information was almost available in the
rune data. Unfortunately, all the single byte encodings were listed
as "NONE" encoding.
So I adjusted localedef tool to provide more information about the
encoding. For example, instead of "NONE", the LC_CTYPE used by
fr_FR.ISO8859-15 is now encoded as "NONE:ISO8859-15". The locale
handlers now check if the first four characters of the encoding is
"NONE" and if so, treats it as a single-byte encoding.
The nl_langinfo handling of CODESET was adjusting accordingly. Now the
following is returned:
en_US returns "ISO8859-1"
fr_FR.UTF8 returns "UTF-8"
fr_FR.UTF-8 returns "UTF-8"
zh_Hant_HK.Big5HKSCS returns "Big5"
zh_Hant_TW.Big5 returns "Big5"
es_ES@euro returns "ISO8859-15"
as before, "C" and "POSIX" locales return "US-ASCII". This is a big
improvement. The result of nl_langinfo can never be a zero-length
string and it will always exclusively one of the values of the
character maps of /usr/src/tools/tools/locale/etc/final-maps.
