While using fully uppercase man page titles has been the usual
convention for a very long time, it is rather ugly and something that
some other projects are switching away from.
groff(1) has changed the internal layout for the .Lb doc strings, but to
preserve backwards compatibility we cannot simply rename them, we need
to create new aliases so that these will work with old and new macros.

We mention that these are now superseded by the glibc implementations,
make the headers cope with already declared functions on glibc-based
systems, and document this in the man pages.
We have moved all man pages to section 3bsd, let's do the same for the
page title, and in all the references for uniformity and to avoid
confusions.
