237c4e3a9e 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.

5b32a38a1a It's not CUT (the french would accept that back in 1879) and TUC wasn't
palatable to the rest of the world.  UTC was the compromise.

f0cefaccae Change return type of strptime from const char* to char*.
const char* was wrong and nonstandard.

3f643d87bb ctime_r and asctime_r are not implemented.
prototypes in time.h do not match POSIX.

8a6472b723 Finish _POSIX_PRIORITY_SCHEDULING. Needs P1003_1B and
_KPOSIX_PRIORITY_SCHEDULING options to work.  Changes:

Change all "posix4" to "p1003_1b".  Misnamed files are left
as "posix4" until I'm told if I can simply delete them and add
new ones;

Add _POSIX_PRIORITY_SCHEDULING system calls for FreeBSD and Linux;

Add man pages for _POSIX_PRIORITY_SCHEDULING system calls;

Add options to LINT;

Minor fixes to P1003_1B code during testing.

37486f035f Import strptime(3) into libc. We've got permission by Kevin Ruddy to
modify the original `no modifications' copyright message, and i've
included his mail into the source file.

The common localization functions between strptime(3) and strftime(3)
have been broken out into timelocal.[ch].

f154fbdaa1 struct timespec needs to be useable with just <time.h>, but needs to not
conflict with the kernel visible one.  Make the new stuff not visible if
_ANSI_SOURCE or _POSIX_SOURCE is defined (!) because the new things are
not part of the base 1003.1-1990 standard (or ansi).

339b0f68f2 Define CLOCKS_PER_SEC.
Define CLK_TCK only if _ANSI_SOURCE is not defined.

Don't include <machine/limits.h> to get the definition of CLK_TCK.
CLK_TCK should never have been defined there, and the inclusion
polluted the namespace.
