packaging: ship only a single binary Debian package
We merge the mercurial and mercurial-common binary packages into a
single mercurial package. This is essentially to ease installation (and
upgrade) using a simple "dpkg -i" command. This also simplifies
debian/rules by removing arch (in)dependent cleanups during
installation.
We have the mercurial binary Breaks: and Replaces: mercurial-common so
that the latter will be removed upon upgrade.
Also note the change from "override_dh_install" to
"override_dh_auto_install" in debian/rules: this is because we do not
want "make install" to be run automatically as we need the
--install-layout=deb of "setup.py install" (otherwise, files would end
up in $DESTDIR/usr/local).
