win32: read system rcpath from registry

Using the module name was not always helpful.  It breaks down
when Mercurial is installed as source and when the Mercurial
libs are used by external applications.

This patch allows Mercurial installers to store the system wide
rcpath in the registry, where it can always be found.  HGRCPATH
is a poor option for storing the system wide rcpath, since it
overrides both the system and user rcpaths.

#!/bin/sh

hg init
touch a
hg add a
hg ci -m "a" -d "1000000 0"

echo 123 > b
hg add b
hg diff --nodates

hg diff --nodates -r tip

echo foo > a
hg diff --nodates

hg diff -r ""
hg diff -r tip -r ""
