Summary: Although this change is breaking with the traditional definition of heads in Mercurial, we decided that using bookmarks as heads is sufficient for fbsource use case as well as it matches the git model where every unnamed branch is garbage collected.

Summary: The problem in compute_changed_files is that for 2 parents given instead of producing a list of files that were changed in the merge commit from perspective of both parents it produced the opposite of that. This should fix it

Summary:
This codemod tries not to change the existing behavior of system, only introduce new types specific to Mercurial Revlogs.
It introduces a lot of copypasta intentionally and it will be cleaned in following diffs.

Summary:
Use hgclone_treemanifest instead of hgcloneshallow.
Note that it changes the behaviour of test-infinitepush.t - now it sends
treegroup part too. Since we actually want to send treegroup part during
infinitepush push, that means that the test was broken and now it fixed.

Summary:
Quick recap: gettreepack is a treemanifest wireproto method.
It's used to send treemanifest data to the client. Client sends list of
manifest nodes it's interested in (mfnodes), and list of nodes it already has
(basemfnodes). Server should find the difference and send it back. Client
usually call this wireproto method when it checks out new revision (`hg
update`), but it uses in other cases too (for example, in `hg prefetch`).
Before we supported exactly one mfnode and exactly one basemfnode. This is
usually fine for `hg update` use-case, but `hg prefetch` can request many
mfnodes and can send empty basemfnode. So let's support this too.
Note that current implementation isn't efficient. It uses at most one
basemfnode, meaning that it can send data that client already has. Also for
each mfnode we generate separate stream of changed entries. That means that the
same entries can be fetched many times.

Summary:
As we discussed before, let's add get_name() method that returns MPathElement,
and remove get_path() and get_mpath().
Except for renaming, diff also make repoconfig work with tree manifest, and
fixes linknodes creation in blobimport - previously basename was used instead
of the whole path.

Summary:
Pulling more than one node doesn't work, because mononoke revsets return
children before the parents. In that case mercurial client fails because new
child points to non-existent parents. To fix it let's reverse the output.
It's bad, because we lose the advantages of streaming, but we do it now anyway
because `getbundle()` method returns Bytes. Besides changelog data should be
fairly small.

Summary:
Super-basic implementation of generating changegroup part in getbundle. All it does is sending changelog
entries - so no manifest and no filelog entries. While it's very simple, it may
actually be enough for a real production use-case. With treemanifest and
remotefilelog we don't need to pull anything except for changelog entries,
everything else will be downloaded on demand.

Summary:
We're never going to serve RevlogRepo in production, and we're down to
a single BlobRepo type that will have different backing stores. Remove the
unused trait, and use BlobRepo everywhere bar blobimport and repo_config
(because we previously hardcoded revlog here - we want to change to a BlobRepo
once blobimport is full-fidelity).
