[RFA/doco] Add documentation for observer.[hc] (2nd version)

[Joel Brobecker <brobecker at gnat dot com>]

Here is a second shot at the observer documentation. Hopefully, I
addressed all issues.

2003-03-10  J. Brobecker  <brobecker at gnat dot com>

        * gdbint.texinfo (Algorithms): Add new section describing the
        Observer paradigm.
        (Top): Add menu entry to new observer appendix.
        * observer.texi: New file.
        * Makefile.in (GDBINT_DOC_SOURCE_INCLUDES): Add dependency on
        new observer.texi file.

Thanks,
