When claiming clusters as part of blobstore initialization
or recovery, just call spdk_bit_array_set directly rather
than going through the bs_claim_cluster function. We will
be modifying how runtime cluster allocation works so need
to separate the two use cases. This code is very small so
inlining it has minimal code impact.

The md_page alignment is not really required for md_page
buffers.
Allocating 4k aligned buffers all the time, causes memory
to be heavily fragmented. Due to DPDK keeping track of the
allocation in the same DMA region as the allocation themselves.
Removing this alignment requirement will help DPDK when searching
for the right part of memory in the heap.

We only create one spdk_blob object for a given blob, and just
increase the ref_count if it is opened multiple times. bs_open_blob
would do the lookup for existing opened blobs.
But if the blob is opened again, before the previous open operation
has completed, we would end up with two spdk_blob objects for the same
blob.
Solution is to do another lookup when the open operation completes.
If we find the blob, free the one we just finished opening and return
the existing one instead.
Also added unit test that failed on the existing code but passes now
with this patch.

There is a fatal bug that could easily cause data corruption when using
thin-provisioned blobs. In blob_request_submit_rw_iov(), we first get
lba by calling blob_calculate_lba_and_lba_count(),
blob_calculate_lba_and_lba_count() calculates different lbas according to
the return of bs_io_unit_is_allocated(). Later, we call bs_io_unit_is_allocated()
again to judge whether the specific cluster is allocated, the problem is it may
have be allocated here while not be allocated when calling blob_calculate_lba_and_lba_count()
before. To ensure the correctness of lba, we can do lba recalculation when
bs_io_unit_is_allocated() returns true, or make
blob_calculate_lba_and_lba_count() return the result of
bs_io_unit_is_allocated(), use the second solution in this patch.
By configuring more than one cpu core, md thread will run in a separate
SPDK thread, this data corruption scenario could be easily reproduced
by running fio verify in VMs using thin-provisioned Lvols as block
devices.

After opening the blob for deletion, in _spdk_bs_delete_open_cpl(),
the blob is removed from list of blobs in blobstore.
This is to prevent future _spdk_blob_lookup()s from referencing
blob while it is deleted.
In usual blob deletion path, next step is proceeding with deletion
of the blob by reducing its size to 0 and syncing the blob.
Changes from this point forward are persisted.
Meanwhile in special case of deleting snapshot which has single clone
on it, before above occurs additional steps are performed.
Each of the blobs are opened and their attributes changed.
Failures on those steps are fully recoverable on any errors,
and in such case blob should be added back to the bs list of blobs.
Original code had condition on how many references there were
to blob being deleted, which is incorrect.
Any error on that path should clean up after itself (revert attributes
and close blobs) and re-add the blob.
This change is tested with blob_delete_snapshot_power_failure() UT,
by adding error path in persist - which triggers error in aforementioned
blob delete code path.

When creating snapshot, 'original' blob will end up being a thin provisioned clone.
Before that first thin_provisioned 'newblob' is created during this process.
If the first md sync for 'newblob' fails, it means that only valid references to
clusters are still only present in 'original' blob. The 'newblob' can be safely
cleaned up.
Unfortunetly 'newblob' inherited some of 'original' blob properties before sync.
Cluster maps were already swaped in current cleanup code. But during blob close
of 'newblob' - persist blob code expects clusters to be 0 only for thin_provisioned
blobs. If original blob was thick, then it triggers an assert within persist code.
This patch makes sure to set thin_provision to 'newblob', to align with its creation.
Added asserts to verify that clusters maps are 0's, which should be the case

Meanwhile bs->clean is always set to 1 after load, causing very first
blob_persist to also re-write super block with the super->clean

When the re-write of super block succeeds the bs->clean is set to 0,

This patch resolves issue when:
1) reading super block fails - execution should backoff, to prevent

2) writing super->clean = 0 to the super block fails - execution

new format (Extent Pages) is not backwards compatible.
Meanwhile old format (Extent RLE) is backwards
compatible with older SPDK applications.
Summing up:
Blobstore created pre SPDK 20.01 can only use Extent RLE.
Blobstore created starting with SPDK 20.01 can use both,
Extent Pages and Extent RLE specified by use_extent_table opts.
When use_extent_table is set to true, invalid flag for it is set.
SPDK application pre 20.01, will not load such blob.

Extent table and extent page descriptors are now
set to be default way clusters are serialized on disk.
With this patch UT are ran with and without
extent table.
Changed two asserts in test, since amount is dependent on
which type of serialization is used.

ctx->extent_page signifies if page was allocated
for insertion.
1) It is possible for a thread to claim extent page
on its own thread, and put it in ctx->extent_page.
If conflicting thread allocates another ctx->extent_page,
then it should be freed. This does not mean failure
to insert cluster. As different threads could have
been trying to allocate different clusters,
so condition on line 6716 does not cover it.
If so then it shouldn't be an issue to release
the claimed ctx->extent_page and proceed with updating the
extent page which originally won the race.
NOTE: if clusters were conflicting, then extent_page is
freed in _spdk_blob_insert_cluster_cpl().
2) At this point of _spdk_blob_insert_cluster_msg()
we already verified that there already is
extent page allocated at "*extent_page".
In such case ctx->extent_page will be 0,
and should not be used.

Previously part of function assumed that cluster count
1)means number of clusters in EP and another 2) that it is
following the active.num_clusters (akin to extent_rle).
This was incosistent and showed when using multiple
extent pages to serialize metadata.
This patch changes it to only go with 1), so it is clear
that it means number clusters within particular EP.

Following changes are done in this patch:
1) _spdk_blob_serialize_extent_table now persists
at least single extent page. When num_extent_pages == 0.
2) Minimum valid size of ET descriptor is even without
extent_pages. This is a case when there are no EP,
but we still want to persist num_clusters in ET.
3) Taking above points, redone the loop for serializing
extent pages.
4) Make sure to mark blob dirty if any new extent pages
were allocted.

Size of a blob (thus size of clusters array in mutable data)
is known from extent table descriptor.
Extent pages were read sequentially in order they were
placed in extent table. This meant that cluster
array could have been filled up from beginning to end.
Yet reading extent pages in any other order,
would result in incorrect placement of clusters.
This patch adds first cluster index that is contained within
each extent page. This will allow to read/write
multiple extent pages in parallel, since
we will know where in clusters array to put the cluster idxs.

When replaying md chain for a blob, extent table
descriptor can be read. When it is present, all allocated pages
it points to are now being put into extent_pages array in ctx.
If multiple extent table descriptors are in single md chain,
the array is expanded accordingly.
After replaying single md chain is done, replay extent pages
starting from last one. Replaying extent pages, is similar to
extent_rle in that each allocated cluster is claimed and
number of free clusters in blobstore decreased.
When all extent pages are read, return to
_spdk_bs_load_replay_md_cpl() for continuing replaying
next valid md chain.
