EquivalentWorkingCopyAncestor/RewrittenAs states.
ikostia@ did a similar change in D24142837 (2035a34a0e) to consider Preserved only if
mapping is None. However this diff diff it only for mapping.get() method. Let's do
the same for mapping.get_equivalent_working_copy().

Summary:
The SegmentedChangelogSeeder has the role of constructing a new IdMap for a
given repository. That would happen when a repository is onboarded or when
algorithm improvements are made.
This change comes with small refactoring. We had the Dag which did a bit of
everything. Now the on_demand_update and the seeder functionalities are in
their separate files. The tests from `dag.rs` were moved to the `tests.rs` and
updated to use the seeder and on_demand_update structures.
`SegmentedChangelogSeeder::run` is the main logic added in this diff.

Summary:
This IdMapVersionStore determines which is the latest IdMapVersion that commit
"tailing" processes should use when building new Dag bundles. The "seed"
process will update the versions of the IdMap. The plan for the "seed" process
is to write a new IdMap version to Sql then update the store with a new entry.
New "tailer" processes will then start to use the newly built IdMapVersion.
The tailing processes that will build fresh IdDags for general consumption.
These IdDags will be used by the clone operation. These dags will also be used
by servers instances spinning up.
DagBundles specify (id dag version, id map vession). This pair specified a
prebuilt Segmented Changelog that is ready to be loaded.

Summary:
This diff fixes how syncing of merge commits decides on the `CommitSyncConfigVersion` to use. Old and incorrect behavior just always uses current version from `LiveCommitSyncConfig`. The desired behavior is to reuse the version with which parent commits are synced, and manually sync commits when version changes are needed.
For merges it is more interesting, as merges have multiple parents. The overarching idea is to force all of the parents to have the same version and bail a merge if this is not the case. However, that is an ideal, and we are not there yet, because:
- there are `NotSyncCandidate` parents, which can (and should at the moment) be safely excluded from the list of parents of the synced commit.
- there are `Preserved` parents (which will turn into the ones synced with a `noop` version)
- there are `RewrittenAs` and `EquivalentWorkingCopy` parents, which don't have an associated version.
So until the problems above are solved:
- absent `RewrittenAs`/`EquivalentWorkingCopy` versions are replaced with the current version
- `Preserved` merge parents cause merge sync to fail.

Summary:
Our higher-level goal is to get rid of `CommitSyncOutcome::Preserved` altogether. This diff is a step in that direction. Specifically, this diff removes the creation of "accidental" Preserved commits: the ones where the hashes are identical, although a `Mover` of some version have been applied. There are a few sides to this fix:
- `get_commit_sync_outcome` now returns `Preserved` only when the source and target hashes are identical, plus stored version is `None` (previously it would only look at hashes).
- `sync_commit_no_parents` now records the `Mover` version it used to rewrite the commit (previously it did not, which would sometimes create `Preserved` roots)
- there are now just two ways to sync commits as `Preserved`:
- `unsafe_preserve_commit` (when the caller explicitly asks for it). The idea is to only remove it once we remove the callers of this methods, of course.
- `sync_commit_single_parent` when the parent is also `Preserved`. Note that automatically upgrading from `Preserved` parent to a rewritten changeset is incorrect for now: `Preserved` does not have an associated version by definition, so we would have to use a current version, which may corrupt the repo. Once we get rid of `Preserved`, this case will naturally go away.
- as we now have `update_mapping_with_version` and `update_mapping` (which consumes current version), we need to add explicit `update_mapping_no_version` for preserved commits we are still creating (again, recording a current version is a mistake here, same reason as above)
NB: I've added/changed a bunch of `println`s in tests, leaving them here, as they are genuinely useful IMO and not harmful.

Summary:
We're seeing an issue on the hg servers where the filecache assertion
that if a value is in obj.__dict__ it's also in obj._filecache is broken. This
occurred about 10% of the time in sandcastle jobs. The diff that caused this
went in in April (D21148446 (73c5cb89de)), so it's unclear why it's only cropping up now.
This is caused by the following steps:
1. repo._bookmarks is accessed while _bookmarks is in the _filecache but not in
the __dict__
2. This causes construction of _bookmarks, before it can set it to __dict__
3. Construction of _bookmarks calls repo.invalidate(clearfilecache=True), which
deletes _bookmarks from _filecache.
4. _bookmarks construction completes, and gets set to __dict__ (but now it's
missing from _filecache, so the invariant will fail next time someone checks).
5. Someone accesses _bookmarks later, and the assertion fires.
The fix is to just not clear the filecache during bookmark construction. The
main purpose of this invalidate was to let the changelog be reloaded, and I
think that will still happen since, if there are any new commits in the
changelog, the file size and time will change, triggering a reload next time the
_filecache entry is checked.

Summary:
Adds a subcommand to `eden debug prefetch_profile` to fetch all the files
for a list of profiles or all the active profiles for a checkout.
These profiles (files) can contain lists of file names, or globs of files, eden
will be able to resolve them since this uses the existing prefetch code.
I opted to put this command under `eden debug prefetch_profile` instead
of `eden prefetch` since the command may change to call into eden with out
the list of files (letting eden resolve the active profiles and names). Then
it will no longer resemble prefetch and so long term it may be better homed
here.
