Summary:
This enables dropping in alternative implementations
of LocalStore and adds a MemoryLocalStore implementation for
use in our tests.
This diff doesn't change the default storage option for the
eden server. I'll look at adding such an option in a follow up diff.

Summary:
Add LocalStore::WriteBatch class so that LocalStore users
can manage own batches independently. This makes it safer to
perform concurrent batched updates as the current implementation
assumes (incorrectly) that it has exclusive ownership of the batch mode setting.

Summary:
This makes several improvements to the hg import tester script:
- If no --edenDir flag is specified, initialize a new temporary directory to
keep the RocksDB data store.
- Add a `--rocksdb_options_file` flag to allow controlling the options used for
the RocksDB store.
- Add an --import_type flag to allow explicitly selecting if we should test
the flat manifest or tree manifest import code.
- Add a --flat_import_file flag, to allow testing a pre-generated flat manifest
input data file, rather than retrieving the data from mercurial. This allows
benchmarking only the C++ import code, and eliminating the python portion of
the import. The input file can be generated by running
`hg_import_helper.py --manifest <revision>`

Summary:
This change makes it so that all of the C++ code related to the edenfs daemon
is now contained in the eden/fs subdirectory.

Summary:
previously, the importer would read the entire manifest
and emit data to the store as it resolved complete directory entries.
The entire manifest data would be buffered and sent out to the store.
In the scenario where one subtree has been modified and a commit has
been made, only the parents of the subdirectory need to be hashed
and stored, but we would compute and try to store everything anyway.
While this diff can't avoid having to compute hashes for everything (we need
tree manifest data for that), by breaking the import into two passes we can
potentially avoid interrogating the LocalStore about every tree in the entire
manifest during an import; we only need to store the trees that are missing and
can simply cut out sub trees that are already present.
This saves us IO at the expense of buffering the manifest tree in memory
for the duration of the first pass; it is an acceptable trade off.

Update copyright statements to "2016-present". This makes our updated lint

Summary:
Move the eden/fs/importer/hg code to eden/fs/store/hg. This import code is
only used by the HgBackingStore, so logically it belongs together.
The eden/fs/importer/git directory was already moved into eden/fs/store/git by
D3448752, so this makes the mercurial code similar.
