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

[Carmelo Amoroso]

commit: http://git.uclibc.org/uClibc/commit/?id=ab38c21ada116672ceed99e4f387dd93ac8e2dd2
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

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.
