Support for platforms that we don't support FIPS on doesn't need to be
in the module. Also, functions for dealing with whether fork-unsafe
buffering is enabled are left out because they aren't implementing any
cryptography and they use global r/w state, making their inclusion
painful.

This restores the original version of delocate.go, with the subsequent
bugfixes patched in. With this, the FIPS module builds with GCC and
Clang, with and without optimizations. I did patch over a variant of the
macro though, since it was otherwise really wordy.
Playing games with sections was a little overly clever and relied on the
compiler not performing a number of optimizations. Clang blew threw all
of those assumptions.

Most C standard library functions are undefined if passed NULL, even
when the corresponding length is zero. This gives them (and, in turn,
all functions which call them) surprising behavior on empty arrays.
Some compilers will miscompile code due to this rule. See also

Add OPENSSL_memcpy, etc., wrappers which avoid this problem.

There's a __pragma expression which allows this. Android builds us Windows with
MinGW for some reason, so we actually do have to tolerate non-MSVC-compatible
Windows compilers. (Clang for Windows is much more sensible than MinGW and
intentionally mimicks MSVC.)
MinGW doesn't understand MSVC's pragmas and warns a lot. #pragma warning is
safe to suppress, so wrap those to shush them. This also lets us do away with a
few ifdefs.

Historically, OpenSSL has used callbacks for anything thread related,
but we don't actually have that many threading libraries to worry about:
just pthreads and Windows (I hope).
That suggests that it's quite reasonable to handle threading ourselves,
and eliminate the need for users to remember to install the thread
callbacks.
The first user of this would be ERR, which currently simulates
thread-local storage using a lock around a hash table keyed by the TID.
(Although I suspect that change will need some CMake work in order that
libpthread is automatically included with libcrypto when linking tests
etc, but not on Windows and without lots of ifs.)
