sigtimedwait:
- provide __sigtimedwait_nocancel
- use __SYSCALL_SIGSET_T_SIZE instead of _NSIG / 8
- do not provide __sigtimedwait
- guard a section to avoid failure on archs if SI_TKILL/SI_USER are not defined
sigwaitinfo:
- simply use sigtimedwait since that handles cancellation already
sigwait:
- use non-cancellable functions (sigtimedwait, sigsuspend)
- get rid of code already done in __sigtimedwait_nocancel

Define a common view of __errno_location, __h_errno_location in common header
and use that everywhere, __uClibc_main.c is no special.
The rule adopted:
for enabled threads we make in libc the __GI_x() variants strong, x() weak
and (should) provide another strong x() in libpthread.
If threads are disabled, even the __GI_x() variants are weak.
_stdio_init,_stdio_term,_locale_init: make all hidden weak in common header

Change uint32_t to u_int32_t and uint8_t to u_int8_t, removing
completely the dependency on stdint.h.
Based on patch by Timo Teraes <timo.teras@iki.fi>. His comment:
This also fixes a major bug that stdlib.h includes stdint.h. Things
might go very wrong because stdint.h has conditional defines and
if stdlib.h is included before #define's for stdint.h we end up
missing things and breaking builds (e.g. openjdk).
