Summary:
Thrift setter API is deprecated since it doesn't bring any value over direct assignment. Removing it can reduce build-time and make our codebase more consistent.
If result of `s.set_foo(bar)` is unused, this diff replaces
s.set_foo(bar);
with
s.foo_ref() = bar;
Otherwise, it replaces
s.set_foo(bar)
with
s.foo_ref().emplace(bar)

Summary:
The `tm_mon` field returned by `localtime_r()` has a range of 0 to 11.
We want to show human-readable month numbers of 1 to 12 in the fsck directory
name and log timestamps. Fix the formatting by adding 1 to the `tm_mon`
value.

Summary:
Implement the repair() logic for InodeDataError, MissingMaterializedInode, and
OrphanInode.
The most common errors we see after an unclean system reboot is an inode file
not being present at all (`MissingMaterializedInode`), or it being present but
empty (`InodeDataError`). When either of these errors occurs for a directory
it also produces `OrphanInode` errors, as all of the children entries in the
directory are no longer part of the directory hierarchy.
This implements repair logic for these three error types. The repair behavior
is largely similar to the Python version in `eden/cli/fsck.py`, with some
minor changes to the output paths in the `lost+found/` repair directory. This
also includes more unit test to better exercise handling when `InodeDataError`
and `MissingMaterializedInode` errors occur inside an orphan subdirectory that
needs to be extracted to `lost+found`

Summary:
Implement OverlayChecker::computePath().
This also updates it to return a structure which can better represent
information if the inode is part of an orphaned subtree, which prevents us
from figuring out the full path to the root of the checkout.

Summary:
This ports much of the Python logic in `eden/cli/fsck.py` to C++, so that
the edenfs daemon can invoke it directly during mount initialization when
necessary.
This initial diff just contains the code to scan for errors, without any
repair logic.
This also includes some improvements to the logic for efficiency. For
instance, we compute less state during the initial scan phase. This makes the
scan phase faster, at the expense of making some of the repair steps slightly
more expensive if errors are found. This newer C++ scan logic is
significantly faster than the old Python version: scanning 260,000 inode files
took around 1m20 second for the Python code, and runs in under 3 seconds with
the new C++ code. (On an SSD with the files in question already warm in the
kernel cache.)
