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:
Previously, the logic that added data to a mutable history pack was required to
add it in the correct order (all entries for a certain file at once, and in
newest-first order). This required the callers to jump through weird hoops if
the data came in out of order or at different times in the transaction.
This patch moves the ordering logic to be inside MutableHistoryPack, so callers
can add the data in any order they wish, and it will get sorted before being
serialized.
This does add memory pressure to things that read a lot of history, like repack.
If this becomes a problem we may want to add a 'historypack.flush()' api that
let's us tell the history pack it's ok to flush it's current contents to disk.
Test Plan: Ran the tests

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.

Summary:
Previously the treemanifest auto-tree-creation logic only produced data packs
containing the actual contents of the tree blobs. This lost history information
which is important for our ability to efficiently repack the data files.
This patch creates history packs during pull as well. A future patch will also
create history packs for the local tree blob store.
Test Plan: Updated the tests to cover this

Previously we were relying on mfrevlog.revdiff() to produce the delta for us.
This only showed us what files were added/modified, as compared to p1, and we
had to use a heuristic to know what files were deleted (by looking at the list
of files in the commit metadata). Merge commits have a different criteria for
what is in the commit metadata (it only contains entries where the file is
different from both parents), so we can't use it for the same heuristic. So
let's fall back to a normal manifest diff for merge commits, since they are
rare.
Adds a test for verifying that conversion of merge commits into a tree works.
