Require stdint.h

Browse Source 
stdint.h belongs to the compiler (as opposed to inttypes.h), so by
requiring a C99 compiler we can also require stdint.h
unconditionally.  Remove configure checks and other workarounds for
it.

This also removes a few steps in the required portability adjustments
to the imported time zone code, which can be applied on the next
import.

When using GCC on a platform that is otherwise pre-C99, this will now
require at least GCC 4.5, which is the first release that supplied a
standard-conforming stdint.h if the native platform didn't have it.
