LibC: Add support for posix_madvise(..)

Browse source 
Add the `posix_madvise(..)` LibC implementation that just forwards
to the normal `madvise(..)` implementation.

Also define a few POSIX_MADV_DONTNEED and POSIX_MADV_NORMAL as they
are part of the POSIX API for `posix_madvise(..)`.

This is needed by the `fio` port.
