When collation support was brought in, the second and third
arguments in __collate_range_cmp() were changed from int to
wchar_t, breaking the ABI. Change them to a "char" type which
makes more sense and keeps the ABI compatible.
Also introduce __wcollate_range_cmp() which does work with wide
characters. This function is used only internally in libc so
we don't export it. Use the new function in glob(3), fnmatch(3),
and regexec(3).

packed LC_COLLATE binary formats. These were generated with the colldef
tool, but the new LC_COLLATE files are going to be generated by the new
localedef tool using CLDR POSIX files as input. The BSD-flavored
version of localedef identifies the format as "BSD 1.0". Any
LC_COLLATE file with a different version will simply not be loaded, and
all LC* categories will get set to "C" (aka "POSIX") locale.
This work is based off of Nexenta's contribution to Illumos.
The integration with xlocale is John Marino's work for Dragonfly.
The following commits will enable localedef tool, disable the colldef
tool, add generated colldef directory, and finally remove colldef from
base.
The only difference with Dragonfly are:
- a few fixes to build with clang
- And identification of the flavor as "BSD 1.0" instead of "Dragonfly 4.4"

load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter. Also
adds support for per-thread locales. This work was funded by the FreeBSD
Foundation.
Please test any code you have that uses the C standard locale functions!

currently cached data. It allows a number of nice things, like: removing
fallback code from single locale loading, remove memory leak when LC_CTYPE
data loaded again and again, efficient cache use, not only for
setlocale(locale1); setlocale(locale1), but for setlocale(locale1);
setlocale("C"); setlocale(locale1) too (i.e. data file loaded only once).
else, it is equivalent to strdup(). So, we will check if the substitution
tables are trivial at the load time, and possibly save 2 calls to
__collate_substitute() in strcoll().
Still, __collate_substitute() should not exist.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
inside libc. Add collate_range_cmp as alias to __collate_range_cmp
for temp. backward compatibility.
collate_range_cmp will be replaced with direct code for each
external program for compatibility with the rest of world
