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:
Decouple inode number assignment from materialization status.
The idea is that we will always assign entries an inode number and
track whether an entry is materialized otherwise. This is necessary
to give consistent inode values across remounts.

This is the type of a tree entry, which may be another tree, so
FileType is not an accurate name.

I want to rename FileType to TreeEntryType so I removed this one first

Summary:
Our Model TreeEntry code was a bit too general - in reality, both git
and hg only support a handful of specific tree entries: regular files,
executable files, symlinks, and trees. (git also supports
submodules.) This diff delays the expansion of a TreeEntry's type
into a full mode_t.

Summary:
This begins adding an EdenMount::diff() method, which walks through the inode
tree and reports differences from the current source control tree state.
My intent is to eventually update the Dirstate code to use this diff()
function, and to remove the existing getModifiedDirectories() logic. The
getModifiedDirectories() code is currently incorrect, as it reports
materialized directories, which is not the same as directories that are
modified from the current source control state.
The ignore processing logic is not currently implemented in EdenMount::diff(),
but it should be relatively straightforward to add in a subsequent diff.

Summary:
Replace the one very basic checkout unit test with several tests that
more thoroughly test file modification changes. More tests for
directory changes and file type changes still need to be added, but this is a
first step for now. I will continue adding more tests in upcoming diffs.

Summary:
The FakeTreeBuilder class in D4609587 provides a lot of the same functionality
as the TestMountBuilder class, but is not restricted to being used only at
mount initialization time. (It also provides more powerful functionality for
controlling the ordering of events when loading data from the ObjectStore.)
This switches all of the existing tests to use FakeTreeBuilder rather than
TestMountBuilder, and removes the TestMountBuilder class.
One difference is that FakeTreeBuilder adds data to the FakeBackingStore, while
TestMountBuilder previously put data directly into the LocalStore. This
shouldn't really make much difference for the behavior of the code. Putting
data in the FakeBackingStore gives us more control over when data is available
during load operations, and exercises slightly more of the normal ObjectStore
code path.

Summary:
Add a FakeTreeBuilder class to make it easier to create Tree structures in the
FakeBackingStore using path names. Previously the test code had to manually
chain together Trees and Blobs. FakeTreeBuilder lets callers call setFile()
with a path name to define the file layout. The files that were defined then
get converted into Tree and Blob data when finalize() is called.
This is similar to the existing TestMountBuilder::addFile() API. However,
TestMountBuilder only populates the LocalStore. FakeTreeBuilder populates
the FakeBackingStore instead. The FakeBackingStore class allows tests to have
much more control about when objects appear ready from the backing store,
allowing control over the order in which Futures are fulfilled during the test.
