GDB debugger mode for Emacs in ELPA

[Nick Roberts <nickrob@snap.net.nz>]

I have updated the GDB debugger mode in the Emacs Lisp Package Archive at
http://tromey.com/elpa (couretesy of Tom Tromey).  This is much improved and
now provides a good basis for future inclusion in Emacs.

It comprises of modified gud.el and a file called gdb-mi.el which replaces
gdb-ui.el.  When installed, this overrides the current files and invoking M-x
gdb will use GDB/MI directly (starts with "gdb -i=mi").  When deleted ('d'
followed by 'x' in Package Menu mode), the files are deleted and old
functionality restored.

It would be helpful if others could test/develop it.

Here's some background for those who are interested

The file gdb-ui.el uses an interface for GDB called annotations.  This involves
marking up GDB's output, which is really intended to be read by humans.  This
output changes with time and has variable formatting, so a more stable and
precise machine interface called GDB/MI is being developed.  In future some
features of GDB will only be available through GDB/MI so it is essential that
Emacs migrates to it.
