[git commit nptl] libc: Add missing header for memset

[Carmelo Amoroso]

commit: http://git.uclibc.org/uClibc/commit/?id=cbff4254e48ff39f5930f972edc6dc9213161727
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/nptl

Silence compiler warning by adding the missing string.h header
to include memset prototype.
Do some code tidy-up removing commented out libc_hidden_proto macros
in the meanwhile.
