subrepo: add the parent context to hgsubrepo

This brings parity with gitsubrepo and svnsubrepo (which already reference their
parent), and will be used in an upcoming patch.

I'm a bit concerned that the parent context could get stale (consider what
happens when the parent repo is reverted for example).  I tried adding the
parent context to the substate tuple so that the parent is available everywhere
a state change is possible, but that made submerge() unhappy.  Even with
removing the parent context inside submerge(), I wasn't able to get all of the
test diffs fixed.

But since the other subrepos reference their parent too, if there is a problem,
it is a preexisting one (that nobody seems to be running into).  It can be fixed
if/when it pops up.

  $ hg init
  $ mkdir a
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ hg ci -m m a

  $ mkdir a b
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ cd b

Relative delete:

  $ hg ci -m m ../a

  $ cd ..
