Summary:
This patch allows compaction to occur in multiple background threads
concurrently.
If a manual compaction is issued, the system falls back to a
single-compaction-thread model. This is done to ensure correctess
and simplicity of code. When the manual compaction is finished,
the system resumes its concurrent-compaction mode automatically.
The updates to the manifest are done via group-commit approach.
Test Plan: run db_bench
Summary:
Created a tool that runs multiple threads that concurrently read and write to levelDB.
All writes to the DB are stored in an in-memory hashtable and verified at the end of the
test. All writes for a given key are serialzied.
Test Plan:
- Verified by writing only a few keys and logging all writes and verifying that values read and written are correct.
- Verified correctness of value generator.
- Ran with various parameters of number of keys, locks, and threads.

Summary:
A simple CLI which calles DB->CompactRange()

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
