Y2038: add _TIME_BITS supportaaribaud/y2038

This makes all previously defined Y2038-proof API types, functions and
implementations the default when _TIME_BITS==64 and __WORDSIZE==32 (so
that 64-bit architectures are unaffected).

Note: it is assumed that the API is consistent, i.e. for each API type
which is enabled here, all API functions which depend on this type are
enabled and mapped to Y2038-proof implementations.
