Publish explicit_memset and consttime_memequal in userland libc.

Remove the double-underscore from the userland versions, and do the
weak alias dance instead, now that these are public parts of libc.

As discussed on tech-userlevel:

https://mail-index.netbsd.org/tech-userlevel/2013/06/24/msg007843.html
(option 3)

Make explicit_memset match memset's return value.

Replace consttime_bcmp/explicit_bzero by consttime_memequal/explicit_memset.

consttime_memequal is the same as the old consttime_bcmp.
explicit_memset is to memset as explicit_bzero was to bcmp.

Passes amd64 release and i386/ALL, but I'm sure I missed some spots,
so please let me know.
