Rename src/regex.c to src/regex-emacs.c.

This is in preparation for using Gnulib regex for etags,
to avoid collisions in include directives.
* src/regex-emacs.c: Rename from src/regex.c.
* src/regex-emacs.h: Rename from src/regex.h.  All uses changed.
* test/src/regex-emacs-tests.el: Rename from test/src/regex-tests.el.
