module request: gmalloc

[Sam Steingold]

some platforms have malloc implementations with extra features like 
randomizations, and some applications cannot handle those features.
thus emacs (and clisp) come with gmalloc.c by Mike Haertel.
It would be nice if it were offered by gnulib, so that I won't have to have my 
own special login to handle the --with-gmalloc configure option and could 
instead get the gmalloc module from gnulib and --with-included-malloc (???) 
would DTRT.
thanks.
Sam.
