Description
memset_s is C11 addition, and is already required by some software out there (libressl?).
FreeBSD has recently introduced it, so we can port their implementation.

I think that memset_s() and the constraint handlers that it needs can be done separately (as was done in FreeBSD), and will set a start for other parts.

Re-reading the standard, looks like we guarantee all of the bounds-checked functions to be available only if we define __STDC_LIB_EXT1__, so with partial implementation we can avoid the definition for the moment.
