[libstdc++] <cstring> fix (PRs 2767 2977 2989 2992 and others)

[Stephen M. Webb]

Here's the patch for the <cstring> and <string.h> headers to clean up the
(known) conflict, ambiguities, and missing definitions.  If results are good and
there is general agreement, this change can be extended to the other C headers.

Bootstrapped on i686-pc-linux-gnu with gcc version 3.1 20010604 (experimental).
No new testcase failures.

There should be 5 files attached to this message.  Automake will need to be run.
