narrow: widen when files are excluded by sparse and not included by narrow
In a repo where some directories are included by narrow and the complement are
excluded by sparse, it was previously impossible to widen either because trying
to widen narrow would complain that the requested files are outside the sparse
checkout and trying to widen sparse would complain that the requested files are
outside the narrow checkout.
This changes the `hg tracked --addinclude` command to only actually update any
newly accessible files in the dirstate if they are also accessible via sparse.

Corrupt an hg repo with a pull started during an aborted commit
Create two repos, so that one of them can pull from the other one.
$ hg init source
$ cd source
$ touch foo
$ hg add foo
$ hg ci -m 'add foo'
$ hg clone . ../corrupted
updating to branch default
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo >> foo
$ hg ci -m 'change foo'
Add a hook to wait 5 seconds and then abort the commit
$ cd ../corrupted
$ echo "[hooks]" >> .hg/hgrc
$ echo 'pretxncommit = sh -c "sleep 5; exit 1"' >> .hg/hgrc
start a commit...
$ touch bar
$ hg add bar
$ hg ci -m 'add bar' &
... and start a pull while the commit is still running
$ sleep 1
$ hg pull ../source 2>/dev/null
pulling from ../source
transaction abort!
rollback completed
