Summary:
This is currently calling `Buf::bytes()` in order to get a `&[u8]` out of
`Bytes`, but this method isn't actually guaranteed to return all data in the
`Buf`: https://docs.rs/bytes/0.5.6/bytes/trait.Buf.html#tymethod.bytes
> Note that this can return shorter slice (this allows non-continuous internal representation)
In practice this is fine because `Bytes` does in fact have a contiguous
internal representation (which is why we can call `as_ref()` on it), but let's
do the more correct thing here.
(I happened to spot this while looking into the feasibility of a Bytes 0.5 ->
Bytes 1.x upgrade, where this `bytes()` method was renamed to `chunk()`)

Summary:
In order to sync changesets we need to know what was the latest synced
changeset from a given source. Previously we wanted to store this data in sql,
however later we decided to store it in the file in the repo. The main reason
for doing that is that storing data inside the repo gives us both blame and
history, while database can't provide that.
This diff implements that - removes all the sql-related code for storing latest
synced changesets and instead puts the data inside the file in the repository.
Note that we still using sql to store mapping between (source, target)
changesets.

Summary:
This diff implements FSCK for EdenFS Windows.
On Windows, users can still modify EdenFS mounts even when EdenFS is not
running, which may cause mismatch between EdenFS state and on-disk view. This
subsequently may cause issues when EdenFS is running again (such as permission
error, not seeing added entries in `hg status`, etc..).
This diff adds FSCK to EdenFS Windows. It is not exactly same as what fsck
traditionally do on *NIX systems. We are still dubbing it as FSCK since it
works at the same place as eden fsck.
At startup, FSCK will crawl the EdenFS mount to compare the overlay state with
disk state. It then synchronizes the overlay view with what the user has on
disk. Note Windows does not always permit user to modify the mount, it only
allows changes in certain situation. In particular, when the directory is in
Full state, this diff takes advantage of that so we can finish the scanning by
only scans such directories.
One limitation of Windows FSCK is that, it cannot reliably tell if the user
deleted a directory or file from dirty placeholder directories. This is because
ProjectedFS will hide untouched entries under dirty placeholder directory when
EdenFS is not running, and there is no way we can tell if the entry is gone
because of user deletion or hid by ProjectedFS.
This is not perfect but acceptable to some extent. One possible failure scenario is:
1. User creates a directory named `foo`.
2. User writes a file to that directory (`foo/bar`).
3. EdenFS then stops running.
4. User then deletes the entire `foo` directory on disk.
5. EdenFS starts again, `foo` will be recrated with an empty `bar` file. This
will still correctly show in `hg status`, and the user is able to delete
them again.

While looking at the previous diff, I noticed that a significant amount of
memory was used by the loading promise. Since this loading promise is only used
when an inode is being loaded, its usage is the uncommon case: there should be
significantly more inodes being loaded or unloaded than loading at any given
time in EdenFS's lifetime.

Summary:
The InodeMap can be extremely hot when issuing tons of requests to EdenFS.
Unfortunately, it still needs to do memory allocation due to its use of
folly::Future. By switching to ImmediateFuture we can avoid the memory
allocation, speeding it up slightly.
For the NFS dispatcher, this moves the call to `semi()` inward, allowing us to
target specific inode methods to convert next. For the Fuse dispatcher, I've
simply converted the ImmediateFuture into a Future directly, keeping the rest
of the code unchanged, a subsequent change will convert the dispatcher code to
ImmediateFuture.

Summary:
This is to mimic the folly::Future API which allows the `get` and `getTry` to
throw if the Future isn't ready. One difference is that the ImmediateFuture API
has a default argument of a max duration instead of having a separate method.
Since chrono durations are expressed as intmax_t (64-bits on systems supported
by EdenFS) a max duration is virtually infinite.

DurhamG discovered that setting max_background in fuse_init_out allows
a larger number of concurrent FUSE requests. The documentation
indicates it's intended to affect background requests like readahead,
but empirically you can observe increased live FUSE requests with `rg

large amount of concurrency and we want to avoid blob and tree fetches
to block FUSE IO when not necessary.
