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
```

ebb9bc3f5a Allow reading multiple chunks at once 
* When repairing multiple chunks at once and any of its repair
  failed, the whole read request and repair work will fail
* Rename read_repair3 and read_repair4 to do_repair_chunks and
  do_repair chunk in machi_file_proxy
* This pull request changes return semantics of read_chunk(), that
  returns any chunk included in requested range
* First and last chunk may be cut to fit the requested range
* In machi_file_proxy, unwritten_bytes are removed and replaced by
  machi_csum_table

3e975f53b8 Allow read_chunk() to return partial chunks 
This is simply a change of read_chunk() protocol, where a response of
read_chunk() becomes list of written bytes along with checksum. All
related code including repair is changed as such. This is to pass all
tests and not actually supporting partial chunks.

d3fe7ee181 Pull write-once files over to clean branch 
I am treating the original write-once branch as a prototype
which I am now throwing away. I had too much work interleved
in there, so I felt like the best thing to do would be to cut
a new clean branch and pull the files over and start over
against a recent-ish master.

We will have to refactor the other things in FLU in a more
piecemeal fashion.
