Add timezone and daylight symbols for XSI compatibility.

unregistering callbacks if the DSO is unloaded.  Move the callback
handling from libpthread to libc, though libpthread still overrides the
inner call to handle locking and thread-library reinitialization.
Major version bump for both libc and libpthread.

routines on hppa, the cause for sha512-parisc subtly misbehaving has been
found: despite having fallback pa1.1 code when running on a 32-bit cpu, the
shift constants used in the sigma computations in sha512 are >= 32 and are
silently truncated to 5 bits by the assembler, so there is no chance of
getting this code to work on a non-pa2.0 processor.
However, the pa1.1 fallback code for sha256 is safe, as it never attempts to
shift by more than 31, so reenable it again.

that should never have been installed.

What's worse, the tzfile.h that gets installed is over 20 years old
and doesn't match the real tzfile.h in libc/time.  This makes the
tree safe for /usr/include/tzfile.h removal.  The TM_YEAR_BASE
define has been moved to time.h temporarily until its usage is
replaced by 1900 in the tree.  Actual removal of tzfile.h is pending
a ports build.  Based on a diff from deraadt@

hard way by henning@.
I can't see anything wrong in the generated assembly code yet, but building
a libcrypto with no assembler code but sha512_block_data_order() is enough
to trigger Henning's issue, so the bug lies there.

Printing strerror() in that case will say result too large, even if rounds is
