the file is also freed after that, so here we combine the cache free and

Currently we will free the cache buffers in the file R/W

buffer reclaim regulary, so that we don't need to free
the cache buffer in the Rocksdb thread context. By
doing this, we can also remove the global cache buffer

we use this statement:

It means that in this test case, length_flushed are
accessed by two different threads, so better to
use another new variable length_flused with volatile
before the variable definition. Then our ut will not hang.

We flush a cache buffer once it's filled. When the write
for that cache buffer has completed, we look to see if
there's more data to flush. Currently if there's *any*
more data to flush, we will flush it, even if it's not
a full buffer.
That can hurt performance though. Ideally we only want
to flush a partial buffer if there's been an explicit
sync operation that requires that partial buffer to be
flushed. Otherwise we will end up writing the partial
buffer to disk, and then come back and write that data
again later when the buffer is full.
Add a new unit test to test for this condition. This
patch breaks one of the existing unit tests which was
designed specifically around a RocksDB failure condition.
Change that file_length unit test to now write exactly
one CACHE_BUFFER, which still tests the general logic
making sure that we don't confuse the amount of data
flushed with the value written to the file's length
xattr.

Data can get implicitly flushed as cache buffers are filled. But
the length xattr is only written in response to a sync or close
operation. So we cannot just look at the amount of data flushed,
and ignore the sync operation if all of the data written has been
flushed - we still need to write the length xattr.
This also adds a unit test which reproduces the original problem.
Fixes issue #297.
