[MAINT] src/mmalloc maintainers

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

This directory is probably best described as one of GDB's forgotten
siblings.  At present it isn't clear what the maintenance policy is. 
With that in mind I'd like to propose:

	GDB's host/native maintainers have implicit check-in
	rights to the src/mmalloc tree.  If there isn't a
	relevant host/native maintainer than the head maintainer
	ends up with the problem :-)

I can't see anyone doing anything to that directory tree unless they are
a native/host maintainer and then the only thing would be fixing
configury problems.

I'm almost tempted to include target maintainers.  I suspect, however,
that getting the native expert a chance to look things over would be
safer.

thoughts?

	Andrew
