When last clone of a snapshot is being deleted
we remove that snapshot from snapshots list.
We should not do that as it still works as a
snapshot and it is read-only, but it does not list
as a snpashot from get_bdevs. Instead remove snapshot
entry from the list when blob that represents that
snapshot is being removed.

Finish the sequence first, before calling _spdk_bs_free().
Otherwise synchronous bs_devs (like we use in the unit
tests) cause the sequence memory to get freed via
_spdk_bs_free() and then we try to finish the sequence.
This eliminates the need for g_scheduler_delay and
_bs_flush_scheduler() in the blob unit tests. But don't
remove them - they will be useful in upcoming unit tests

There was some thinking that we would need to allocate
I/O channels on a per-blob basis to handle dynamic
resizing during I/O. Making spdk_blob an opaque handle,
with the existing spdk_blob structure renamed to
spdk_blob_data was a first step towards making that
happen. But more recent work on blobstore has
simplified the resizing approach, so this spdk_blob_data
is no longer needed. So revert it.

Patch adds internal version of xattr functions to allow
operations on internal xattrs, which are not visible to
upper layers.
When there is at least one internal xattr set, also
SPDK_BLOB_INTERNAL_XATTR flag is set in invalid_flags to prevent
loading this blob in previous spdk versions.

This change will allow reusing this structure for both internal
and external xattrs as well as in functions having optional xattr,
but missing other options (i.e. snapshot, clone implemented in next patches)

This will be needed for thin provisioning, since a write
I/O may result in needing to insert a cluster into the
blob and that write I/O may not have been performed
on the metadata thread.
