For namespaces with end-to-end protection information, metadata size
of exactly 8 bytes, and extended LBA configured, the NVMe driver would
calculate the size of the data block incorrectly. The NVMe spec has a
special provision for this specific case (8-byte metadata only) and
PRACT = 1 that requires that the host does not send the metadata as part
of the host memory buffer.
To fix this, clean up the calculation of the per-block data transfer
size by adding a new extended_lba_size field in the namespace, which
represents the total size of data to be transferred per block based on
the namespace's configured metadata size and whether it transfers
metadata as part of the data buffer. Then add the special case for
PRACT = 1 and PI configured and extended LBA in the R/W helper
functions.

Convert the number parsing function into a linear sequence with a goto
label for each state, rather than a single loop with a state variable.
This makes the code easier to read and also improves speed (better
branch prediction and smaller inner loops for the common case).
On my test system, jsoncat citylots.json > /dev/null improves from
~1.7s to ~1.2s.
This changes behavior of some number parsing test cases: inputs matching
the number grammar as defined by JSON will be returned even if there is
trailing garbage, consistent with the rest of the parser. For example,
the input 01 will be parsed as a valid number 0 followed by trailing 1.
This only makes any difference when the full input is a single
number value, since if the value was nested in an object or array, the
trailing garbage will not match the expected syntax and the whole parse
will fail with SPDK_JSON_PARSE_INVALID (e.g. [00 will parse the first 0
as a number and then fail on the second 0, since only a comma or right
square bracket would be accepted).

An old prototype SPDK AHCI driver would return
TASK_SET_FULL if all NCQ slots were full on a given
disk. This would kick the SCSI task back to the LUN
to be retried later. Since then, we have pushed
responsibility onto the bdev modules themselves
to handle this kind of queueing/retry logic.
Removing this logic allows us to make some additional
changes that enable tasks to get completed inline without
an extra event callback to handle completion. We also
no longer need to worry about checking if pending tasks
need to be executed in the complete_task() routine, since
the execute() routine will now always exhaust the pending_task
list.

The other simplifications to probe_info and trid made the

The probe_info was reduced to just containing a
transport_id, so remove probe_info entirely.

Scanning the transport may result in both new
devices and removed devices, so pass the callback
for both operations.

Simplify the arguments to nvme_transport_ctrlr_scan to take
a transport id that identifies the discovery service (or
NULL to scan PCIe).
Further, separate scan into two functions - scan and attach.
Scan is for scanning an entire bus, attach is for a specific
device.

When we enabled the ERL1 configuation, for the DATAIN task release
process, we will queue the task to the SNACK list firstly, and then
remove the list when got ACK from initiator, but for this part of
logic, the reference count of primary task was not released correctly.

Change the PCI enumeration API to individual functions per device type
so that only the drivers that are actually in use get linked into the
final executable. All of the common code is still shared internally in
the env_dpdk library.

This allows us to print better error messages when connecting to a
subsystem that exists but does not allow a specific host.
Additionally, we can now return the correct error code for a host that
is not allowed.

Considering the process can be terminated in the cases like ctrl+c,
kill command or memory fault, the ref is tracked in the per process
structure spdk_nvme_controller_process and whenever there is other
process attaches or detaches the controller, a scan will be issued
to cleanup those unexpectedly exited processes.

This could use some better validation to make sure failures only happen
during the reset, but this at least gets the nightly tests running
