Summary:
Enhance check-ext script to be more strict:
- Only one foreign extension is allowed: `remotenames`
- Require explicit path for in-repo extensions to avoid wrong extensions
being tested
This would make the test more predicatable since system extensions
will be less likely to be imported. Explicit path is better than
setting `PYTHONPATH` since `hgext/name.py` could override
`hgext3rd/name.py` regardless of `PYTHONPATH`.

Summary:
This adds a remote tree datastore to the store, so if we don't have a tree on
local disk, we can reach out to the server for it.
This also makes a small change to fastmanifest to use get() instead of
getmissing() to test if the tree is available. getmissing() would indicate the
tree is missing if it wasn't local, while get() will attempt to fetch it from
the server.
Test Plan: Added a test

Summary:
The treemanifest tests were setting the configs on both the client and the
server, without telling the server it was a server and without setting it up
appropriately to be a client. This caused the tests to fail in a future patch.
Let's move the treemanifest config to the clients, since that's the only bits
being tested here.
Test Plan: Ran the tests

Summary:
Previously treemanifest and fastmanifest were largely unaware of each other. If
the fastmanifest was available, we'd use that. If not, we'd try tree. Then we'd
fall back to flat. When comparing two manifests, this could cause problems since
if one manifest was fast and one was tree, we'd have to fall all the way back to
flat manifests to compare them.
This patch adds the ability to build a treemanifest from a fastmanifest for
inmemory manifests that were copied from a commit that has both a fastmanifest
and a treemanifest. We do it by diff'ing the inmemory fastmanifest with the
commit fastmanifest, then applying that diff to the commit's treemanifest. Then
we can compare that tree with the other tree.
This is particularly useful when doing things like 'hg up master' after a pull.
The new master commit probably has a treemanifest, but doesn't yet have a
fastmanifest, while the commit the user is on probably has both. Now we can do
that hg up without having to parse a full manifest.
Once treemanifest has been enabled, every commit (both pulled and user created)
should have treemanifests. Therefore this case should never happen when
comparing two normal commits. So in theory, the only way to hit this case is
when Mercurial does a manifest.copy() on a manifest that has a fastmanifest
(like when reading a workingctx which must copy the commit manifest and apply
working copy changes), since the copy will choose to copy the fastmanifest and
leave the treemanifest behind. This patch addresses that case, so I think there
shouldn't be other cases.
Test Plan: Adds a test that covers this case.
