Summary:
This is first step of my effort to reduce size of librocksdb.a for use in mobile.
ldb object files are huge and are ment to be used as a command line tool. I moved them to `tools/` directory and include them only when compiling `ldb`
This diff reduced librocksdb.a from 42MB to 39MB on my mac (not stripped).
Test Plan: ran ldb

Summary: The queries will come from stdin. One key per line. The output will be in stdout, in the format of "<key> ==> <value>" if found, or "<key>" if not found. "--hex" uses HEX-encoded keys and values in both input and output.
Test Plan: ldb query --db=leveldb_db --hex

Summary: This command accepts key-value pairs from stdin with the same format of "ldb dump" command. This allows us to try out different compression algorithms/block sizes easily.
Test Plan: dump, load, dump, verify the data is the same.

Summary:
A simple CLI which calles DB->CompactRange()
Can take String key's as range.
Test Plan:
Inserted data into a table.
Waited for a minute, used compact tool on it. File modification time's
changed so Compact did something on the files.
Existing unit tests work.

Summary:
Create a tool to iterate through keys and dump values. Current options
as follows:
db_dump --start=[START_KEY] --end=[END_KEY] --max_keys=[NUM] --stats
[PATH]
START_KEY: First key to start at
END_KEY: Key to end at (not inclusive)
NUM: Maximum number of keys to dump
PATH: Path to leveldb DB
The --stats command line argument prints out the DB stats before dumping
the keys.
Test Plan:
- Tested with invalid args
- Tested with invalid path
- Used empty DB
- Used filled DB
- Tried various permutations of command line options
