Replace dot-dot relative pathing with SRCTOP-relative paths where possible This reduces build output, need for recalculating paths, and makes it clearer which paths are relative to what areas in the source tree. The change in performance over a locally mounted UFS filesystem was negligible in my testing, but this may more positively impact other filesystems like NFS. LIBC_SRCTOP was left alone so Juniper (and other users) can continue to manipulate lib/libc/Makefile (and other Makefile.inc's under lib/libc) as include Makefiles with custom options.

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. MFC after: 1 week

time32.c
Changed all paths to be relative to src/lib instead of src/lib/libc so that all these makefiles can be used to build libc_r too. Added .if ${LIB} == "c" tests to restrict man page builds to libc to avoid needlessly building them with libc_r too. Split libc Makefile into Makefile and Makefile.inc to allow the libc_r Makefile to include Makefile.inc too.

Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP} if not already defined. This allows building libc from outside of lib/libc using a reach-over makefile. A typical use-case is to build a standard ILP32 version and a COMPAT32 version in a single iteration by building the COMPAT32 version using a reach-over makefile.

Compile contrib/tzcode/stdtime/localtime.c with -fwrapv, since it relies on signed integer overflow wrapping. Otherwise mktime(3) and timegm(3) can hang, in case the timestamp passed in struct tm is not representable in a time_t. Specifically, any timestamp after 2038-01-19 03:14:07, in combination with a 32-bit time_t. Note that it would be better to change the code to not rely on undefined behaviour, but it is contributed code, and it is not entirely trivial to fix the issue properly. MFC after: 3 days

Use latest Arthur Olson timezone code rather than that supplied with 4.4. The code is almost identical to the 4.4 versions, but this organization should make it easier to merge new versions in the future.
