Expose PlatformFileLock/Unlock, fix locking in Chromium's leveldb Env
The base::CreatePlatformFile() flags PLATFORM_FILE_EXCLUSIVE_READ/WRITE
are ineffective on existing files on POSIX, and can't be used to
implement the locking scheme required by leveldb.
Add PlatformFileLock/Unlock which have the correct semantics, and
use those in ChromiumEnv. Also, crib code from leveldb's env_posix.cc
to handle in-process exclusivity which is not guaranteed by
file locks.
