libc: Add strverscmp(3) and versionsort(3)

Add a strverscmp(3) function to libc, a GNU extension I implemented by
reading its glibc manual page. It orders strings following a much more
natural ordering (e.g. "ent1 < ent2 < ent10" as opposed to
"ent1 < ent10 < ent2" with strcmp(3)'s lexicographic ordering).

Also add versionsort(3) for use as scandir(3)'s compar argument.

Update manual page for scandir(3) and add one for strverscmp(3).

Add strchrnul(), a GNU function similar to strchr(), except that it returns

Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a
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!
