Summary:
Instead of trying to maintain two hgrc.dynamic's for shared repositories,
let's just always use the one in the shared repo. In the long term we may be
able to get rid of the working-copy-specific hgrc entirely.
This does remove the ability to dynamically configure individual working copies.
That could be useful in cases where we have both eden and non-eden pointed at
the same repository, but I don't think we rely on this at the moment.

Summary:
On Windows, the following pseudo code:
int fd = open("file");
struct stat st;
fstat(fd, &st);
Will have a different st_dev than the following code:
struct stat st;
stat("file", &st);
Since the FileChangeMonitor uses st_dev as a way to compare if a file
changed, the config is always reloaded.
For our use case, the filesize and its mtime should be enough to know if the
configuration changed, so let's only use these 2 on Windows.

Summary:
On Windows calling `connect()` on an AF_UNIX socket path that does not exist
creates a file at that location. This is problematic as it now prevents
servers from binding to that path. Even if the server attempts to remove the
file in order to bind, clients attempting to call `connect()` can race with it
and make binding fail.
This updates our client connection code check to see if the file exists before
attempting to call `connect()`. This can still race with a server that is
trying to remove an old socket and re-bind, but it at least makes the race
less likely to happen.

Summary:
Talked with xavierd last week and we can use LocalStore's `get_missing` to determine if a blob is present locally. In this way we can prevent the backingstore crate from accidentally asking EdenAPI for a blob, so better control at EdenFS level.
With this change, we can use this function at the time where a blob import request is created with confidence that this should be short cheap call.
This diff should not change any behavior or performance.

When doing discovery, for repos with long master lines and infrequent
branches, picking a random set of sample commits could result in not picking the
master, and therefore having to do very long commit graph traversals to check
ancestors against the other samples.
To prevent this, let's pick the N most recent commits instead of a random
sample. This should generally get the master commit into our sample.

Summary:
We have a number of error enums that wrap an existing errors, but fail to
register the underlying error as a `#[source]`. This results in truncated
context chains when we print the error. This fixes that. It also removes a
bunch of manual `From` implementation that can be provided by thiserror's
`#[from]`.
This also required updating the `Display` implementation for those errors. I've
opted for not printing the underlying error, since the context chain will
include it. This does mean that if we print one of those errors without the
context chain (i.e. `{}` as opposed to `{:#}` or `{:?}`), then we'll lose out a
bit of context. That said, this should be OK, as we really shouldn't ever being
do this, because we'd be missing the rest of the chain anyways.

Summary:
This removes our own (Mononoke's) implementation of failure chains, and instead
replaces them with usage of Anyhow. This doesn't appear to be used anywhere
besides Mononoke.
The historical motivation for failure chains was to make context introspectable
back when we were using Failure. However, we're not using Failure anymore, and
Anyhow does that out of the box with its `context` method, which you can
downcast to the original error or any of the context instances:
