David Benjamin 17cf2cb1d2 Work around language and compiler bug in memcpy, etc. 
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
https://www.imperialviolet.org/2016/06/26/nonnull.html

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

/* IMPLEMENTATION NOTES.
*
* The 32-bit hash algorithms share a common byte-order neutral collector and
* padding function implementations that operate on unaligned data,
* ../md32_common.h. This SHA-512 implementation does not. Reasons
* [in reverse order] are:
*
* - It's the only 64-bit hash algorithm for the moment of this writing,
* there is no need for common collector/padding implementation [yet];
* - By supporting only a transform function that operates on *aligned* data
* the collector/padding function is simpler and easier to optimize. */
