Summary: Even if blobs have different hashes, they could have the same contents. For example, if between the two revisions being compared, if a file was changed and then later reverted. In that case, the contents would be the same but the blobs would have different hashes. Currently, `getScmStatusBetweenRevisions()` would report false positives in this case. This is also needed so we do not report false positives in `getScmStatus()` when hit this code path

Summary:
Add a new thrift API for computing the difference between the working
directory and a given source control commit.
This has the following differences from the old getScmStatus() commit:
- The parameters are accepted in a GetScmStatusParams structure now.
This makes it easier for the server-side C++ implementation to tell which
parameters have actually been specified by the caller. This will make it
easier to extend this API in the future without having to replace it with a
new function call again.
- The return value is a GetScmStatusResult, which includes both the ScmStatus
and the EdenFS version number. This will allow code like `hg status` to get
both the status results and the EdenFS version in a single call, without
needing to make multiple separate thrift calls.
- This new call will return an error if the caller requests the status against
a commit that disagrees with EdenFS's view of the current commit. Because
the individual `hg` command line processes do not perform any
synchronization of their own when reading the working directory parent,
they can often call EdenFS with stale parent information, or while a
checkout is currently in progress. This new behavior will reject the
request with an error, rather than having EdenFS perform a potentially very
expensive status computation when the results probably aren't actually
useful to the caller anyway.

Summary:
Some Unix applications (notably, nfsd) create regular files using vfs_create, which ends up invoking the `mknod` system call rather than `open`, which for historical reasons only supported socket creation with Eden. However, since Eden supports regular files, we can broaden the FUSE mknod handler to support regular files as well.

Summary:
## Backstory
Pyre was throwing errors in my diff (D17747558) regarding an extraneous fixme. Turns out PyreBot has been adding and removing these fixmes during version updates (see D17135557 and D16183608), so I suspect it's something to do with the Pyre version. Anyways, I figured it'd be easier to do the annotation than to remove the fixme and risk Pyre throwing the same error in a later diff.
## What I did
I added the Key type (Path) and Value type(ExpectedFileBase). mypy then started throwing an error regarding __iter__ returning the wrong type because it wanted an iterator over keys rather than values. Fixed that and added .values() to the for loop.

Summary:
This diff removes the logic that consumes the legacy bind
mount list and mounts them on startup. That functionality has been
replaced with the eden redirect command.
Instead of performing the bind mounts in the server, the server will
now run `eden redirect fixup` to apply that configuration.
This diff also changes the behavior of performBindMounts: previously, if the
bind mount setup failed, we would tear down the entire repo mount. Since we're
now spawning an external process, it is much more likely that something might
fail and result in a bad experience, so we no longer bail out in that case:
we'll continue and leave the bind mounts as-is. The user can then use `eden
doctor` or `eden redirect fixup` to sort things out.

In dev mode builds the `hg_rust` binary isn't guaranteed to work anywhere
other than its original location, due to the way that dev mode builds use
`$ORIGIN` in the binary's `RPATH` setting. This happened to work up until now
as the hg_rust binary did not have any separate libraries, but I plan to add
one on the `chg` library.

I also cleaned up the error message slightly when `eden start` is used

exception thrown was unhandled so it also printed a python backtrace. Now the
code throws an exception that is caught by the higher level command line code,
so it is printed in a more user-friendly way.

Summary:
This diff adds a single repo-wide `.eden-redirections` file that is used to
record the redirection configuration for the repo.
The redirection configuration code knows to look at this file and fold it in to
the effective configuration; the legacy bind mounts are applied first, then the
repo redirection configuration and then the user specified redirections.
The intent is that a `post-update` hook will invoke `eden redirect fixup` to
apply the configuration from the repo, and to have the eden daemon also
trigger that after (re-)mounting the repo.
In the future we can extend this to allow different profiles to be enabled
or disabled, but for now this is the minimum viable product.

Summary:
This is part of the effort to make our bind-mount configuration more
visible and easier to change.
The idea is to generalize the concept of redirection and add a command to help
manage it.
The `eden redirect add` subcommand allows creating one of two different kinds
of redirection:
* `bind` - allocate some space using `mkscratch` and mount it into the repo
* `symlink` - allocate some space using `mkscratch` and create a symlink
that points to it from the repo
On Linux we use bind mounts to implement `bind` but on macOS, which doesn't
have a bind mount concept, we create a sparse disk image file that can grow
to match the size of the disk on which it is created (in practice these are a
7-15MB in size to start and grow as the user stores data into them).
The `eden redirect del` subcommand allows removing a redirection, including
the legacy `bind-mounts` configuration from `.eden/client/config.toml`.
The `eden redirect list` subcommand lists the effective set of redirections,
both from the new redirections configuration and the legacy `bind-mounts`
configuration, along with their state.
The `eden redirect fixup` subcommand iterates over the effective set of
redirections and can remove and reinstate any that are in a broken state.
