Summary:
Currently, phrevset picks the "successor" that has the maximum revision
number. That depends on the assumption that larger revision numbers
are modified last. Howevver, that's not always true with commit cloud sync. For example, in my repo I have D21179514 modified from 63768bf43
to 684612d5d. Phabricator has 63768bf43. Local successor is 684612d5d,
but the revision number of 684612d5d is smaller than 63768bf43:

Summary:
Make it so that the autopull functions just describe what to do (using the
`pullattempt` struct) instead of having the side effect directly. This will be
useful in multiple cases:
- The actual autopull logic becomes easier to implement.
- The revset autopull layer can merge `pullattempt`s to fetch things in one go.
- The `pull -r` logic can reuse the `pullattempt`s to translate what to pull
(ex. from `D1234` to a commit hash).
This has subtle changes that multiple "remote"s are no longer properly
supported. That is probably fine in our production use-cases but we might
want to revisit if we want to support remotes "properly". Currently, this
greatly simplifies things due to the fact that "infinitepush" or
"infinitepushbookmark" have to be used in certain cases.

Summary:
The revset optimization makes unknown names harder to extract. For example,
`(or (list "a" "b" "c"))` will be optimized to `(_list "a\0b\0c")` and it
becomes harder to extract `"a"`, `"b"`, and `"c"`.
Move the unknown name extraction logic to before the optimization step to solve
it.

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.

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.

This diff should not change any behavior or performance.

Summary:
D21316793 is blocked from landing because there are a few targets in eden that are running pyre via buck targets integration.
We can't do custom version overrides for projects that are using a mix of local configurations and buck integration, because buck doesn't provide an interface for setting the equivalent pyre version override.
We're moving away from buck targets integration for pyre across the board, and I've run a codemod over the project to clean up all of the buck typing integration (including some residual mypy) as well as updated type ignores / fixmes accordingly.
Let me know if you have any concerns; upon skimming it looks like most changes are either converting `type: ignore`s into fixmes, or removing `type: ignores`.

Summary: Mercurial Infinitepush normally records received bundles into the `forwardfillerqueue`, which is later tailed by the commit cloud `forwardfiller` in order be replayed onto Mononoke. Now I am adding a reverse filler, which means that we will have two such queues and sync in two directions. Therefore, in order to avoid infinite loops we need to distinguish cross-backend bundle replay from genuine pushes. I propose to use `crossbackendsync` bundle2 param to indicate that no recording is needed.

Summary:
Building on the previous two commits, this adds a test which performs the following steps:
- does an infintiepush push to a Mercurial server
- looks into the `forwardfillerqueue`
- runs commitcloud forwardfiller's `fill-one` to replay the bundle to Mononoke
- verifies that this action causes the commit to appear in Mononoke
As this test uses `getdb.sh` from Mercurial test suite, it needs to be whitelisted from network blackholing (Note: we whitelist mononoke tests, which run with `--mysql` automatically, but this one is different, so we need to add it manually. See bottom diff of the stack for why we don't use `--mysql` and ephemeral shards here).
