7086899941 Reorg merkle tree code into a library
Was a service previously. Now contains both merklet
and the naive implementations.  Put construction
timing stuff into the test.

Tests are not truly meaningful yet.

f7358424e4 Trim command and GC prototype implementation
* maybe_gc/2 is triggered at machi_file_proxy, when chunk is deleted
  and the file is larger than `max_file_size`
* A file is deleted if all chunks except 1024 bytes header are trimmed
* If a file is going to be deleted, file_proxy notifies metadata_mgr
  to remember the filename persistently, whose filename is
  `known_files_<FluName>`
* Such trimmed filenames are stored in a machi_plist file per flu
* machi_file_proxy could not be started if the filename is in the
  manager's list. Consequently, any write, read and trim operations
  cannot happen against deleted file.
* After the file was trimmed, any read request to the file returns
  `{error, trimmed}`
* Disclaimer: no tests written yet and machi_plist does not support
  any recovery from partial writes.
* Add some thoughts as comments for repairing trims.

* State diagram of every byte is as follows:

```
state\action| write/append   | read_chunk       | trim_chunk
------------+----------------+------------------+---------------
 unwritten  |  -> written    | fail (+repair)   | -> trimmed
 written    | noop or repair | return content   | -> trimmed
 trimmed    |  fail          | fail             | noop
```
