1914de0920 blobfs: start a poller to do cache buffer reclaim regularly
Currently we will free the cache buffers in the file R/W
data path, however we can start a thread to do the cache
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
lock in following patches.

beaf69617a blobfs: try to free a valid file cache buffer when allocating new caches
When allocating a new cache buffer, we will pick up a file and try to
free cache buffers with this file, but sometimes the file lock maybe
hold by other thread, so we use pthread_spin_trylock() here, when
pthread_spin_trylock() return a negative value, we will break the
loop, this is not efficient as the orginal logic, which may result
cache buffer allocation failure, so we will break the loop only when
there is a valid cache free.

72b9af55fa blobfs: make cache_free_buffers() used for file deletion and blobfs unload
When there is no free cache buffers, we need to free some cache buffers
based on very simple algorithm for now, when deleting a file or unload
the blobfs, there must no dirty caches, there is no cache buffers after
calling spdk_tree_free_buffers(), so we will create another cache free
buffers function which only used in file read/write path.

When testing blobfs with db_bench, there maybe multiple threads will
call alloc_cache_memory_buffer() at same time, and spdk_fs_delete_file_async()
maybe called at same time, and it may release file->tree and file structure
without holding g_caches_lock, so here we will change the
alloc_cache_memory_buffer() to hold the g_caches_lock while releasing
the file cache buffers.

Fix issue #1133.

cdd089a8c5 blobfs: don't flush a partial buffer with no sync pending
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.

e967dcd245 blobfs: ensure length xattr is written even if all data is flushed
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.

125797e07e blobfs: take the spdk_fs_request parameter for flush
Data structure spdk_fs_request has internal spdk_fs_cb_args
for each request, and for some APIs such as truncate they
all use spdk_fs_request as the parameter, so here we also
change flush to use the request parameter too.

bdb1d5713f blobfs: Add trace info for request allocation.
Our blobfs allocates fixed number of reqs on three different channels
(the default size is 512), if the req cannot be allocated, our blobfs
related function will do nothing.

With this debug info added, we can easily know the issues.
If the fixed number of requests are not enough, we need to change the
design, using malloc/free together with the fixed number of requests.

During high presure test, I think that if the reqs are not allocated,
it will cause the sync, flush related issues.

13a58c41ad blobfs: fix the length value of file.
In function spdk_fs_file_stat_async, the
stat.size = f->append_pos >= f->length ? f->append_pos : f->length;

but in spdk_file_get_length, we return f->length.

So generally, it should all use the same method to return the file
length, and this patch will fix this issue.
