When scrubbing to collect commit times for path info logging, its much easier to get correct commit times for manifests by walking from oldest changeset first. That way when any manifest/tree is discovered its from the closest changeset chunk to its creation.
Alternative would have been using the path data from linknode associated changesets to prune out which sub-manifests to walk when walking forward, which is more complicated and would require holding more state (or reloading changesets continuall)

Summary:
There have been a bunch of problems with the previous approach to scmstore, so I'm going to try to start simple, make it feature complete, and then add async integration and factor out generic functionality as appropriate.
This change contains a `TreeStore` implementation with a single, synchronous, batch read method (supporting local storage, memcache, and legacy fallback, with writing missing to cache).
Add `TreeStoreBuilder`, which duplicates the existing `TreeScmStoreBuilder`, which some changes that make it easier to use for this case. I intend to unify these in the future.
Add an inherent impl for `EdenApiTreeStore` that provides subset of the `BlockingEdenApi` trait, which eliminates the need to unpack this type into a different adapter as the old `scmstore` code does. This might not be the right approach here, in reality we only need a `(client: Arc<dyn EdenApi>, repo: String)` here for trees, and that + `ExtStoredPolicy` for files, so we could take the `EdenApiAdapter` approach here too. The only reason we have to do any of this is because when `pyrevisionstore` is called to construct `scmstore` / `contentstore`, all we have is `Arc<EdenApiTreeStore>`. We could also just make the `EdenApiRemoteStore` fields public, and access them through the `Arc`.
Add `add_mcdata` method to `MemcacheStore`, `impl TryFrom<Entry> for McData`, and `impl From<McData> for Entry` for convenience when working with `MemcacheStore` (so we don't need to manually unpack the type and build `Entry`, or manually build a fake `Delta` from `Entry` to write).

I modified `get_local_path` to accept a `PathBuf` by move, which it uses directly, and to not take an `Option` (instead just calling `map` externally, removing some unnecessary unwraps), and for both functions to accept `impl AsRef<Path>` for suffix.

Vertex is old. It no longer makes sense with the current structure. The main
issue is that the dag crate now has VertexName which may confuse readers at
first glance.
When Vertex was added DagId would have been confusing because we had structs
that were named Dag that did not use DagId directly. Those structures are now
renamed and DagId is consistently used for dag crate structures.
The IdMap database would still use the vertex name until someone runs a
migration to rename the column.

Summary:
This updates hg to have a different amount of retry for backoffs requested by
the server and errors.
The rationale is that backoffs are fairly well understood and usually caused by
a surge in traffic where everybody wants the same data (in which case we should
be willing to wait to get it because there is literally no alternative),
whereas general errors aren't predictable in the same way.
We're now effectively at a point on the server side where _all_ our instances
have the exact same load, so if any server is telling you to backoff, that
pretty much guarantees that the whole tier has too much traffic to deal with.
This leaves us with two options:
- Tell clients to wait longer and smooth out the traffic surge.
- Add enough capacity that even our biggest surges don't result in _any_
throttling.
The latter is a bit unrealistic unrealistic given we routinely get egress
variations in excess of 5x (here's an example: https://fburl.com/ods/pidsrqnl),
so this does the former.
This also updates the client to tell the server how many attempts it has left
in addition to how many it used up so far. How many are left is more meaningful
for alerting!
Finally, it adds a bit of logging so that in debug mode you can see this
happening.

Summary:
Passing 64 to preallocate means that the AsyncSocket code will issue reads of
64 bytes, even though the IOBufQueue has significantly more space available. We
can thus pass a bigger size to preallocate to reduce both the cost of
allocation, and the syscall cost. For heavily concurrent client code, this will
allow us to read more than one request per syscall.
The careful reader may have noticed that for very small requests the code may
reallocate more often that it should as it will always reallocate when falling
under 4KB. This is likely to not be an issue in practice.

Summary:
Currently it's hard to test EdenApi related features in hg tests. The Mononoke
test suite can do it but it's too heavyweight. Looking at the API surface of
EdenApi it's actually quite small. So let's add a minimal Rust struct that can
serve as an EdenApi server.
This diff just adds a few minimal features. EdenApi related features and
push/pull support will be added later.
The name "eager" is to make it explicit that the repo is not lazy. I thought
about names like "testrepo" or "serverrepo", but the implementation is
somewhat "sound" to be used as a client, non-test repo. It can potentially
be used as starting point for a real "repo" in pure Rust. So I didn't choose
those names.
(I'm not entirely happy with the name but it's more like a placeholder
that makes it look different from other names for now).

Summary:
This allows an external crate C that implements `EdenApi` to depend on a more
lightweight library just providing `EdenApi` without things like `hg_http`.
Then the `edenapi` crate can depend on C too.
Didn't move it to `edenapi_types` because it would add extra dependencies
(http, http_client, auth, etc.)

Summary:
The `Builder` API is the main API used by external users to obtain an `EdenApi`
client. In the future we want to support different kinds of `EdenApi`, like a
local repo serving it, if `paths.default` is set to something like
`myrepotype:path`. Make `Builder` more flexible to support non-HTTP `EdenApi`s,
by returning `EdenApi` trait objects.
The old builder that is coupled with HTTP is renamed to HttpClientBuilder.

Generic container for a bunch of uniform objects. This is primarily intended
for requests and responses which can be difficult to evolve when the top level
object is an array. For cases where evolution is required we would
probably replace the Batch wrapper with a specialized type. For example,
starting from `Batch<MyRequest>` we would change to:
struct MyRequestBatch {
pub batch: Vec<T>,

Summary:
I want to add prefix lookup functionality to EdenApi.
I considered adding some sort of prefix abstraction to Hg or our wire types.
so that I could use the method that was already implemented. I found the
serialization and conversion logic complicated to reason about. It is easier
to transform the prefix query in a range query and add a range query endpoint.
No need to invent new fancy types and deal conversions.
This diff updates the prefix query implementation to rely on the range query.
The range query is functionality that is more general than prefix lookup.

Summary:
NOTE: there is one final pre-requisite here, which is that we should default all Mononoke binaries to `--use-mysql-client` because the other SQL client implementations will break once this lands. That said, this is probably the right time to start reviewing.
There's a lot going on here, but Tokio updates being what they are, it has to happen as just one diff (though I did try to minimize churn by modernizing a bunch of stuff in earlier diffs).
Here's a detailed list of what is going on:
- I had to add a number `cargo_toml_dir` for binaries in `eden/mononoke/TARGETS`, because we have to use 2 versions of Bytes concurrently at this time, and the two cannot co-exist in the same Cargo workspace.
- Lots of little Tokio changes:
- Stream abstractions moving to `tokio-stream`
- `tokio::time::delay_for` became `tokio::time::sleep`
- `tokio::sync:⌚:Sender::send` became `tokio::sync:⌚:Sender::broadcast`
- `tokio::sync::Semaphore::acquire` returns a `Result` now.
- `tokio::runtime::Runtime::block_on` no longer takes a `&mut self` (just a `&self`).
- `Notify` grew a few more methods with different semantics. We only use this in tests, I used what seemed logical given the use case.
- Runtime builders have changed quite a bit:
- My `no_coop` patch is gone in Tokio 1.x, but it has a new `tokio::task::unconstrained` wrapper (also from me), which I included on `MononokeApi::new`.
- Tokio now detects your logical CPUs, not physical CPUs, so we no longer need to use `num_cpus::get()` to figure it out.
- Tokio 1.x now uses Bytes 1.x:
- At the edges (i.e. streams returned to Hyper or emitted by RepoClient), we need to return Bytes 1.x. However, internally we still use Bytes 0.5 in some places (notably: Filestore).
- In LFS, this means we make a copy. We used to do that a while ago anyway (in the other direction) and it was never a meaningful CPU cost, so I think this is fine.
- In Mononoke Server it doesn't really matter because that still generates ... Bytes 0.1 anyway so there was a copy before from 0.1 to 0.5 and it's from 0.1 to 1.x.
- In the very few places where we read stuff using Tokio from the outside world (historical import tools for LFS), we copy.
- tokio-tls changed a lot, they removed all the convenience methods around connecting. This resulted in updates to:
- How we listen in Mononoke Server & LFS
- How we connect in hgcli.
- Note: all this stuff has test coverage.
- The child process API changed a little bit. We used to have a ChildWrapper around the hg sync job to make a Tokio 0.2.x child look more like a Tokio 1.x Child, so now we can just remove this.
- Hyper changed their Websocket upgrade mechanism (you now need the whole `Request` to upgrade, whereas before that you needed just the `Body`, so I changed up our code a little bit in Mononoke's HTTP acceptor to defer splitting up the `Request` into parts until after we know whether we plan to upgrade it.
- I removed the MySQL tests that didn't use mysql client, because we're leaving that behind and don't intend to support it on Tokio 1.x.

Summary:
MyRouter is no longer used by Mononoke services, it is deprecated and will stop working when we upgrade the tokio.
This diff removes MyRouter support from Mononoke and simplifies the Mysql connection type struct.
Before we had `MysqlOptions` and `MysqlConnectionType` enum to represent what kind of a client we want to use. Now we use only MySQL FFI so I removed `MysqlConnectionType` completely and put everything into the options struct.
As setting up the connections (aka conn pool) is not an async operation, some of the methods don't need to be async anymore. Because this diff is already enormous, I'm refactoring this in the next one.

Summary:
This command executes native checkout dry run code for updating between specificed revisions
Command tests network and storage perf, without actually affecting working copy
Examples of usages:
1) User reports that when updating between revisions multiple times, they see unexpected fetches, even though they expected that all data should already be in cache. Running this command shows that update between those revs fetches more data then a cache size, so repating fetches are not a surprise
2) People working on storage/network layer optimizations can utilize this command to test performance without messing with their working copy
This command understands nativecheckout.usescmstore config, same way it is used in actual native checkout
