Currently, the benchmark used to assess leveldb changes lives in db/. The codebase also contains two benchmarks against other database engines in doc/bench/. Moving all the benchmarks in one place opens up the way for extracting common code.

- Added a C binding for LevelDB.
May be useful as a stable ABI that can be used by
programs that keep leveldb in a shared library,
or for JNI API.
- Replaced SQLite's readseq benchmark to a more efficient version.
SQLite readseq speeds increased by about a factor of 2x
from the previous version. Also updated benchmark page to
reflect readseq speed up.

- Based on suggestions on the sqlite-users mailing list,
we removed the superfluous index on the primary key
for SQLite's benchmarks, and turned write-ahead logging
("WAL") on. This led to performance improvements for SQLite.
- Based on a suggestion by Florian Weimer on the leveldb
mailing list, we disabled hard drive write-caching via
hdparm when testing synchronous writes. This led to
performance losses for LevelDB and Kyoto TreeDB.
- Fixed a mistake in 2.A.->Random where the bar sizes
were switched for Kyoto TreeDB and SQLite.

- LevelDB patch for FreeBSD. This resolves Issue 22.
Contributed by dforsythe (thanks!).
- Removing Chromium-specific files.
They are now going to live in the Chromium repository.
- Adding a benchmark page comparing LevelDB performance
to SQLite and Kyoto Cabinet's TreeDB, along with
code to generate the benchmarks.
Thanks to Kevin Tseng for compiling the benchmarks,
and Scott Hess and Mikio Hirabayashi for their
help and advice.
