The issetugid() API is supposed to make a strong promise where "0
means it is safe to look at the environment".  Way back in the past
someone on the OpenSSL team responded to the environment access danger
by creating a wrapper called OPENSSL_issetugid, and went to use it a
number of places.  However, by default on systems lacking true
issetugid(), OPENSSL_issetugid returns 0.  0 indicating safely.  False
safety.  Which means OPENSSL_issetugid() fails to make any sort of
promise about safety, in fact it is just the opposite.
Can you believe the OpenSSL team?
This nastiness was noticed over the years, however noone could gain traction
and get it fixed in OpenSSL.  Also see a paragraph about this in

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.

instead of simply zapping it. this can save many syscalls in a program
that repeatedly grows and shrinks a buffer, as observed in the wild.

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.

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@

for overflow. stop talking about old broken systems, there's little use
for such info.

regress tests but causes tls ciphersuite using sha386 to fail; found the
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
actually too small. invalid is less specific, but less incorrect.

instead of disk.  OpenSSL didn't provide a built-in API from loading
certificates in a chroot'ed process that doesn't have direct access to
the files.  X509_STORE_load_mem() provides a new backend that will be
used by libssl and libtls to implement such privsep-friendly
functionality.

remember to set EACCES in bcrypt_checkpass for hash differences.
the higher level crypt_checkpass function will reset errno to EACCES in
all cases, which is probably the right behavior, but this change gives code
working with the lower level functions the correct errno if they care.
