Honor bbdb-message-clean-name-function and bbdb-canonicalize-mail-function consistently
Convert VM path to absolute and canonicalize it
Simplify configure.ac and lisp/Makefile.in
Merge remote-tracking branch 'savannah/master' into suggest-v3.x

Conflicts:
	aclocal.m4 (move changes to m4/bbdb_with_vm.m4)
	configure.ac (trivial manual merge; bump version number)
	lisp/Makefile.in (move changes to lisp/Makefile.am)
	lisp/bbdb.el (trivial manual merge)
	lisp/makefile-temp (remove)
use EMACS rather than EMACS_PROG, and respect --without-vm-dir
invoke AM_PATH_LISPDIR, which finds emacs executable, before checking for VM
