Summary:
The Mercurial convert extension passes around parameters to indicate a commit that needs to be converted from source to sink. For existing converters like Git, this is a simple 1:1 conversion: a commit in the source gets mapped to a commit in the sink, and so they use the source commit hash (sometimes called rev or version in the API) to represent the commit to be converted.
Our converter is much more complicated. Source commits get converted multiple times to account for different ways of mounting it into the destination file system and commit history. The commits are also coming from multiple source Git projects. This means that we need multiple pieces of data to represent a single commit conversion action.
Thus far, we've been trying to meet part of this need by using concatenated strings of (variant, commithash). This logic is breaking down as we add more fields. This commit adds a new immutable object called "conversionrevision" that represents the (variant, source commit hash, source project name, destination path) that is the unique identifier for the individual commit conversions we need to perform. This commit also includes logic for serializing and deserializing these objects as strings (useful because the converter seems to require commit IDs to be strings) and unit tests for all of the new logic.

Summary:
The library already has a way to wrap a Python object into a Rust object that
exposes the Rust Read/Write interface. This is the reverse direction for
the Write interface.
The initial intention is to expose Rust stdout as described in D19702533.
However, I found Python's `sys.stdout.buffer` also enforces utf-8 encoding
on Windows (unless PYTHONLEGACYWINDOWSSTDIO is set). So Python's
stdout actually behaves similarly with Rust's stdout on Windows and is okay
to use. That said, it's still useful to have this abstraction, for streampager [1]
integration.

Summary:
Drop stdoutbytes/stdinbytes. They make things unnecessarily complicated
(especially for chg / Rust dispatch entry point).
The new idea is IO are using bytes. Text are written in utf-8 (Python 3) or
local encoding (Python 2). To make stdout behave reasonably on systems not
using utf-8 locale (ex. Windows), we might add a Rust binding to Rust's stdout,
which does the right thing:
- When writing to stdout console, expect text to be utf-8 encoded and do proper decoding.
- Wehn writing to stdout file, write the raw bytes without translation.
Note Python's `sys.stdout.buffer` does not do translation when writing to stdout console
like Rust's stdout.
For now, my main motivation of this change is to fix chg on Python 3.

Summary:
We've had a small proportion of our users run into problems
with hdiutil and diskimages-helper, where those components get into
an unhappy state and effectively block operating on the redirections.
This diff introduces a new utility that is intended to replace the
use of disk image files with APFS volumes that we mount in the
appropriate places.
The intention is that we will teach `eden redirect` to use this tool
when available, rather than disk images.
macOS's security model is weird: it is perfectly valid for a non-privileged
user to create and delete APFS volumes in the APFS storage container,
but root privs are required to mount it into the VFS.
The intent is that we deploy this utility setuid root to minimize
the fan out--this way we won't need to teach the priv helper about
this kind of redirection.
There are a couple of subcommands demonstrated in the test plan.

Summary:
Begin adding type hints to many of the vfs methods.
These type hints indicate that the vfs objects are always opened in binary
mode. While it is possible to open a vfs in text mode if you explicitly
specify the argument `text=True`, this is very rare. If we run into cases
in the future that do need type hints to indicate TextIO mode I think it would
be better to split those out into completely separate functions, rather than
having functions that sometimes return bytes and sometimes return str based on
the arguments used.
