Using era_info_t and alt_digits_t indiscriminately in strftime and
strftime_l breaks targets not wanting C99 time formats.

Move all locale category structure definitions into setlocale.h and remove
other headers in locale subdir. Create inline accessor functions for
current category struct pointers and use throughout. Use pointers to
"C" locale category structs by default in __global_locale.
