Add routines to convert time_t to/from fixed-bit fields. These routines
serve two purposes: (1) so we can maintain backwards compatibility with
protocols (rwhod, dump, etc...) that either assume time_t is 32 bits or
assume sizeof(time_t) == sizeof(int), or make other similar assumptions.
(2) To tag such routines (by the presence of these calls) for future
cleanup/extension work.

The 32->64 routine, time32_to_time() (when time_t is 64 bits, that is),
is defined specifically to implement temporal locality to properly set the
msb bits of a 64 bit time_t quantity, using the 50 year rule. The locality
code has not been implemented yet (and doesn't need to be for a while),
but that is the intent. This will allow us to maintain backwards protocol
compatibility past 2038.

These routines are intended to be platform and time_t agnostic.

Make ctime_r, asctime_r, gmtime_r, and localtime_r available in libc.

Change return type of strptime from const char* to char*.
const char* was wrong and nonstandard.

Add extern declaration for `tzname[]' to make this header comply better
to POSIX90.

ctime_r and asctime_r are not implemented.
prototypes in time.h do not match POSIX.
