Summary:
After the kernel added readdir caching, my testing uncovered that Eden
was invalidating TreeInode entries incorrectly when new entries were
added. Change TreeInode to distinguish between directory entry changes
and removals (FUSE_NOTIFY_INVAL_ENTRY) and additions
(FUSE_NOTIFY_INVAL_INODE).

Summary:
Several places in edenfs need to represent empty future objects, and were
written before the Future::makeEmpty() method was added. These locations
used Optional<Future> as a workaround.
This updates the code to simply use empty Futures instead of Optional<Future>
now.

Summary:
The two FileInode::isSameAs() methods called FileInode::getSha1(), which
returns a folly::Future object, and immediately called `value()` on the
resulting future without waiting for it to complete first.
This bug dates back to D5430128. However, I suspect it was D7888344 that
actually exposed this issue recently. D7888344 updates the
`RocksDbLocalStore` code to perform work in an I/O thread pool. Before this
change the SHA1 futures were likely always immediately ready, so this bug was
not causing problems.

Summary:
Originally I thought this would help move towards removing a
`future.get()` call from FileInode, but it turned out to not make a difference
to that code.
It does make it a bit less of a chore to deal with the Journal related diff
callbacks added in D5896494 though, and is a move towards a future where we
could potentially return cached and shared instances of these objects.
This diff is a mechanical change to alter the return type so that we can share
instances returned from the object store interface. It doesn't change any
functionality.

Summary:
Update the TreeInode and CheckoutAction to correctly be able to remove
directories during checkout operations. This handles both removing directories
that are newly empty as a result of the checkout, and directories that are
replaced with a file or symlink.
This also refactors the rmdir/unlink code a bit so we can share some of its
logic for doing directory removal during the checkout operation.

Summary:
This updates CheckoutAction to make the old TreeEntry object optional.
This is necessary to support situations where the entry did not exist in the
old source control tree, but does exist in the new tree and also exists locally
on the file system. This situation is always a conflict, so it only applies
when a force checkout is being done.
This diff also refactors the TreeInode::computeCheckoutActions() logic to
combine the processNewEntry/processRemovedEntry/processEntry lambdas into a
single function, as suggested in the code review for D4538516.

Summary:
This is the initial code for implementing checkout.
This isn't quite 100% implemented yet, but I think it's worth checking in this
code as-is, and getting the remaining functionality done in separate diffs.
In particular, a few operations aren't implemented:
- Removing a directory that was deleted in the new revision
- Replacing a directory that was replaced with a file or symlink in the new
revision
- When doing a forced update, replacing a file or directory that did not exist
in the old revision, but that was created locally in the working directory,
and also exists in the new revision.
