Summary:
The `debugmutation` command uses the unfiltered repo to resolve the
user-provided revs. It shouldn't do this unless the user passes `--hidden`.

Summary:
In general, mutation tracking doesn't care about divergence. However, in the
case of rebase, it doesn't make sense to allow divergence to occur if we can
avoid it by omitting some of the commits to rebase.
This makes rebase behaviour more like old obsmarker-based behaviour. This
breaks a test for mutation copying markers, so update those to use metaedit,
which has the copying behaviour for both obsmarkers and mutation. At some
point we should make rebase behave better in these cases.

Summary:
Now that all our repos are treemanifest, let's enable the extension by
default in tests. Once we're certain no one needs it in production we'll also
make it the default in core Mercurial.
This diff includes a minor fix in treemanifest to be aware of always-enabled
extensions. It won't matter until we actually add treemanifest to the list of
default enabled extensions, but I caught this while testing things.

The `-` graphnode can be confusing as `-` is also used for horizontal graph lines.

Use the graphnode `-` for all invisible commits, even obsolete ones.
Users will only see them in their logs if:

Summary:
The pullcreatemarkers extension creates fake markers for landed commits by comparing
the differential revision of draft commits with those of landed commits.
In the future, mutation records will handle lands correctly, however until that stage,

Summary:
Computing mutation entries for all local commits is expensive when there are
lots of local draft commits. Ideally we would have an indexed changelog that
would make these lookups fast, but until we have that, put entries in the

Summary:
The computations for instabilities revsets (`orphan`, `contentdivergent` and
`phasedivergent`) are complex, and aren't really necessary for the way we use
mutation information.
The `orphan` revset can be implemented as an alias for `obsolete():: -
obsolete()`. The other conditions can be detected on a case-by-case basis
later if we need them.

Summary:
Add support for detecting landed commits.
Since we don't currently have an index for successor information in the
changelog, we can only detect the successor relationship for predecessors of
draft commits (for which we build a cache). As a temporary workaround,
make it possible to put mutation records in the mutation store that lead to
landed commits. These will allow land detection to work until we have a
changelog that supports indexing on predecessor.

Summary:
The `mutations` template keyword expands to a list of the results of mutating
the commit. Each element of the list has an `operation` field, which is a
string describing the mutation operation, and a `successors` field, which is a
list of the successor commits for this operation. Sequences of mutations that
result in a single successor are collapsed into a single `rewrite` operation.

Summary:
Add support for mutation information being added when a commit is split.
The top of the final stack is the commit that stores the mutation metadata.
The other commits in the stack are just normal new commits, although the final
commit does record their hashes in its metadata.
Determining when the last commit in the stack happens before it is committed is
a little hard, as the code previously relied on the dirstate ending up clean
to detect a finished split. Instead we look at the patches that come out of
the filter function and see if they match the original patches that were sent
in.
