2022-08-25libc: Add strverscmp(3) and versionsort(3)Aymeric Wibo
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).

2011-11-20Implement xlocale APIs from Darwin, mainly for use by libc++. This adds aDavid Chisnall
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!
