Summary:
Previously, there are 2 configs: `treedirstate.useinnewrepos` and
`format.usetreestate`. They are both related to dirstate format and conflict
with each other. This patch unifies them into a single config
`format.dirstate`.
As we're here, merge `test-fb-hgext-treedirstate-x.t` to `test-dirstate-x.t`
if they were previously copied from `test-dirstate-x.t`

Summary:
Add a config option `format.usetreestate`, which would turn on the new
treestate for new repos.
Treestate does not need manually maintaining "copymap", "otherparentset",
"nonnormalset". The one single tree is the source of truth of everything.
So some code like `copymap.pop` etc. are disabled on treestate path.

This adds a test extension to check that the non-normal set contains the
expected entries. It wraps several methods of the dirstate to check that
the non-normal set has the correct values before and after the call. The
extension lives in contrib so that paranoid developers can easily
enable it to make sure that the non-normal set is consistent across more
complex operations than the included tests.
