If a reconnect fails, we restore the original

9f5e3c99f2 nvme: add spdk_nvme_ctrlr_is_fabrics()
We map the SPDK_NVME_TRANSPORT_* values directly to
the NVMe-oF trtype values.  Since PCIe isn't
Fabrics, we choose 256 which is outside of the
8-bit trtype range of values.

So we can just check if trtype >= 256 to determine
if the trid is for fabrics or not.  This is
preferable to checking PCIE || VFIOUSER in case
additional non-fabrics transport types are added
in the future.

I considered taking a trid as the parameter instead,
but went this route since it is consistent with
the existing spdk_nvme_ctrlr_is_discovery().

d6f6ffd274 nvme: add NVME_CTRLR_STATE_CONNECT_ADMINQ
Connect the adminq as part of controller initialization
instead of controller construction.

We never actually 'connected' the adminq for
PCIe or vfio-user transports, since its a nop.
But their connect_qpair transport ops function
is also a nop for the adminq, so it's fine to
generically connect the adminq across all transports.

Note that we cannot read registers (cc or csts)
during controller initialization now until after
the adminq has been connected since reading fabrics
registers depends on a connected adminq.  This gets
special cased for now, but eventually reading
cc and csts will need to be part of the state machine
itself to make it asynchronous.

spdk_lw_thread uses stats from above and keeps track of two points in time:

- last_stats reflecting stats from previous gather_metrics stage

1)
Before this patch current_stats were duplicated in snapshot_stats.
There is no need for that so now they are removed.

2)
Removed _spdk_lw_thread_get_current_stats() since it would be copying
current_stats to current_stats, thus not perform any action.

Having this check here will make sure that no matter
the changes in event framework, scheduler dynamic will work.

Removed the place that updated last_stats if they weren't
yet updated at least once (first scheduling period iteration).
In this case after change to _get_thread_load() will be the same,
as only the latest iteration will be used to calculate thread load.

42ad9d0379 lib/blob: resize open_blobids on bs load
open_blobids holds bit array of currently open blobs,
this is a way for quicker determination than iterating
over all blobs. See patch introducing it:
(30ee8137)blob: Add a bitmask for quickly checking which blobs are open

That patch added resizes of this bit array to bs init
and bs recovery path (not shut down cleanly).

But that patch skipped over bs load from a clean shutdown.
This resulted in blob open having multiple blob pointers that
target the same blob id.

Fixes #1937

ceaa0c7fa9 lib/blob: complete multiple persists
When blob persist starts, there can already be multiple
of such requests pending. It is possible to complete
a set of persists at once, if blob state after their
execution would be the same. This is the case when
persists are already pending when a particular persist
request is started.

This patch implements such mechanism by introducing
persists_to_complete queue, containing entries that
were previously queued up before starting the current
persist request. If there are any entries in this queue,
further requests are put into pending_persists.

When first request from persists_to_complete is persisted,
completions are issued for all requests on that queue at once.
If at that point there are any new entries on pending_persists,
all of them are put into persists_to_complete. Persist process is started
again with the first request from that queue.
