layouts: fix crash when importing hgsubversion itself (issue #402)
Mercurial extensions are a bit weird: they aren't normally in
sys.path, so you can't assume that "import hgsubversion" works.
Luckily, Mercurial sneaks a little treat into sys.modules so that
"import hgext_hgsubversion" does work. In fact, to get things working
*as a Mercurial extension*, all that's needed is that trivial change
to two import lines, in layouts/detect.py and layouts/standard.py.
Unfortunately, hgsubversion is also imported as a Python module, in
its own test suite. In that context, there is no "hgext_" trick --
unless we do it in ourselves, which I've done in TestBase.setUp().
That would work fine ... except that test_util imports from
hgsubversion, which ends up importing hgsubversion.layouts.{detect,standard},
which want the "hgext_" trick to work. But it hasn't been done yet
when we're still importing; it doesn't happen until setUp() runs.
So make those two imports happen late, in the functions that need them.
Incidentally, this is only necessary to support Mercurial <= 2.7.
Mercurial got a bit smarter in 2.8:
