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!

This is currently a nop on FreeBSD, but is import for other platforms (or in the future) where PTHREAD_MUTEX_INITIALIZER is not simply zero.

But also like getline(), we can't prototype it by default right now because it would break too many ports.
