Summary:
The newly changed `LZ4_decompress_safe` is unhappy about empty buffer. So let's
check empty revision explicitly.
Test Plan: Added a test

Summary:
This diff makes 2 changes to v1 packfile metadata:
1. Move `key` in a metadata entry to before `size`.
```
old: [entry-size: 2 byte] [key: 1 byte] [data: var length]
new: [key: 1 byte] [data-size: 2 byte] [data: var length]
```
Previously `entry-size == 0` does not make sense.
2. Use binary to represent sizes, instead of ASCII.
Related utility methods are cleaned up a bit so it's harder to make mistakes.
Test Plan: Updated existing tests

Summary:
This diff implements getmeta in C and enables related tests.
Now all content stores support `getmeta`.
Test Plan: Run existing tests.

Summary:
This diffs add a `getmeta` method to all content stores. The cdatapack code is
modified to pass the tests, it needs further change to support `getmeta`.
The datapack format is bumped to v1 from v0. For v1, we append a `metadata`
dict at the end of each revision. The dict is currently used to store revlog
flags and rawsize of raw revlog fulltext. In the future we can put more data
like a second hash etc, without changing API or format again.
This diff focuses on correctness. A datapack caching layer to speed up
`getmeta` will be added later.
Tests are updated since we write new v1 packfile now and the format change
leads to different content and packfile names.
`Makefile`, `ls-l.py` are added to make tests easier to maintain.
Test Plan: Updated existing tests.

Summary:
A future patch which renamed cdatapack.so to cstore.so pointed out that our
test-remotefilelog*.py tests are running against the system remotefilelog. Let's
move them to a .t test that sets the appropriate PYTHONPATH.
Test Plan: Ran the tests
