Summary:
The EdenFS codebase uses folly/logging/xlog to log, but we were still relying
on glog for the various CHECK macros. Since xlog also contains equivalent CHECK
macros, let's just rely on them instead.
This is mostly codemodded + arc lint + various fixes to get it compile.

Summary:
This introduces a class to manipulate the metadata for all the entries in a
tree. This adds serialization and deserialization to this class so that it can
be written to the local store.
Why do we need this? We need some way to easily check when we have already
fetched metadata for a tree and do not need to refetch this from the server to
avoid expensive network requests. Later diffs add functionally to store the metadata
for tree entries in the local store under the tree hash using this class.

Summary:
In following diffs we will use scs to prefetch meta-data for files, so that this data
will be available with out fetching the file content (which will improve build times
on eden).
SCS indexes trees by an scs specific hash (blake2 content hash) or by the commit
hash and path. Since this is different from the eden hashes and mercurial
hashes, we need another index to go between the current ids we have in eden
and identifiers for scs.
This introduces a proxy hash that serves as this conversion. Because we have
commit hashes around in eden right now, this is an easier route to indexing
into scs currently.

Summary:
Now that loading too many blobs only GCs the blob cache, treat cached
trees as ephemeral again.

Summary:
Instead of clearing every single cached object when the total size
exceeds the ephemeral storage limit, keep a limit per object type and
only clear those that exceed their quota.

Summary:
EdenFS no longer uses the blobsize keyspace. To avoid wasting space,
clear and campact it on startup, along with any keyspaces we
deprecated in the future.
