Stanislau Hlebik ea794c29b4 mononoke: make it possible automatically select parents when manually rewriting 
Summary:
One of the things that megarepo_tool can do is to manually rewrite a commit
from one repo to another with a particular commit remapping version.

e.g.

```

source repo
X
|
P

target repo
X'  <- rewritten X
|
A   <- commit that exists only in target repo
|
P'  <- rewritten P

```

Previously it always required manually setting the parents in the target repo
i.e. in the example above we'd need to tell that A is the new parent of
rewritten commit.

However this is not always convenient. Sometimes we just want megarepo_tool to take
parents in the source repo (i.e. P in the example above), remap them to large repo
(i.e. P' in the example above), and use P' as a target repo parent.

This diff adds a special option that lets us do so.

Mononoke

Mononoke is a next-generation server for the Mercurial source control system, meant to scale up to accepting thousands of commits every hour across millions of files. It is primarily written in the Rust programming language.

Caveat Emptor

Mononoke is still in early stages of development. We are making it available now because we plan to start making references to it from our other open source projects.

The version that we provide on GitHub does not build yet.

This is because the code is exported verbatim from an internal repository at Facebook, and not all of the scaffolding from our internal repository can be easily extracted. The key areas where we need to shore things up are:

  • Full support for a standard cargo build.
  • Open source replacements for Facebook-internal services (blob store, logging etc).

The current goal is to get Mononoke working on Linux. Other Unix-like OSes may be supported in the future
