For iscsi read/write, expected_data_xfer_len
is 0, dxfer_dir is set to SPDK_SCSI_DIR_NONE.
But we can still have read/write op in SCSI layer.
This patch solves this issue.

This allows the user to connect to multiple remote NVMe-oF targets or to

If the user asked for a specific PCI address in spdk_nvme_probe(), we
need to return 1, not 0, for the other PCI addresses that don't match
when enumerating. 0 means to attach the PCI driver, whereas 1 means to
continue enumerating.
With the previous behavior of returning 0, all NVMe devices would be
attached to the DPDK PCI driver, even if the user did not request for
them to be probed, and further calls to spdk_nvme_probe() would not find
any devices.

This flag prevents the compiler from merging multiple tenative global
variable declarations (e.g. 'int i;' without an assignment) into a
single copy later. In the default (-fcommon) mode, this allows multiple
definitions of an uninitialized global variable to be linked into a
single program without any warnings.

This prevents the need for bdev users and modules to manipulate the
internal bdev_io error.nvme fields.
For now, all non-NVMe error types are treated as a generic device error,
but translation from SCSI to NVMe could be added in the future.

Rather than hard-coding the spdk.io/doc link, change the Doxygen header
to output a link to index.html (the main Doxygen page) so that it will
always point within the current doc tree.
This is important for archived release versions of the documentation,
since their documentation link should point at their own main page, not
the current master doc.

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).

If a blockdev module calls spdk_bdev_io_complete() within its
submit_request function, and the user's completion callback issues a new
I/O, it is possible to cause infinite recursion, consuming all available
stack space.
To avoid this, track whether a bdev_io is being processed by
submit_request, and if io_complete() is called in this case, defer the
completion via an event.
