2044690e6a env: introduce SPDK_MEMZONE_NO_IOVA_CONTIG
Future DPDK versions may drop physical memory contiguity
guarantee for common memzones. DPDK 18.05 introduces
an RTE_MEMZONE_IOVA_CONTIG (0x00100000) flag, which is
documented as follows:

> RTE_MEMZONE_IOVA_CONTIG - Ensure reserved memzone is IOVA-contiguous.
>                           This option should be used when allocating
>                           memory intended for hardware rings etc.

To preserve backward compatibility, SPDK introduces an opposite
flag, SPDK_MEMZONE_NO_IOVA_CONTIG.

8c71c208a2 nvme: check ctrlr process while get ctrlr data in hotplug function.
Fix issue #313.
For multi-process test scenarios, the secondary process may access
controller’s CSTS register in the shared ctrlr list. For this situation,
all the controllers are already in the primary shared ctrlr list, but
then each controller is added one by one in the secondary process, so the
secondary process may access CSTS before it is remapped for the BAR space.

In the rpc_config.sh test case, the spdk_nvme_ctrlr_get_regs_csts function
will be called in _nvme_pcie_hotplug_monitor function before calling
spdk_pci_nvme_device_attach. This step caused the secondary process iSCSI
Target access CSTS before it is remapped for the BAR space.

9c4679bc77 nvme: rename g_pid to g_spdk_nvme_pid
This variable will no longer be static in a future patch.
So make the name a bit more verbose since it will now
be visible outside of the module that defines it.

d76cd984aa nvme: optimize nvme_allocate_request memsets
The memset was zeroing a lot of bytes that get
initialized either later in this function or elsewhere
in the submission code path.  Eliminating these
extra memsets saves a few nanoseconds of CPU overhead
in the NVMe submission path.

Note: one use of the cpl data member depended on
the nvme_allocate_request memset.  Since this use
case is not in the primary I/O path, just memset it
in that specific location before using it.

7dff719f7e nvme: optimize layout of struct nvme_payload
Rather than storing nvme_payload::type explicitly, use the SGL reset
function pointer as an indicator: if reset_sgl_fn is non-NULL, then the
payload is an SGL type; otherwise it is a contiguous buffer type.

This eliminates the one-byte type member from struct nvme_payload,
making it an even 32 bytes instead of 33, allowing the removal of the
awkward packing inside struct nvme_request.

be1c82b7a8 nvme: update the NS identify data according to AER

defines the maximum number of namespaces supported by
this controller, for physical NVMe controllers, the NN
is a fixed number, while here, we set the same rule for
NVMeoF controllers.

After NVMe driver got namespace notice event, it should
update the namespace identify data structure for NS
attach/detach commands.

recursive commands, e.g.: in AER callback we may send a new AER
request, in such case, the current code can't process such
case.  While here, move the completion queue head to next before
any response callback will fix such issue.

practice, since this command is already only sent to controllers that
report NVMe version 1.3 or newer, but let's add the check anyway for
consistency.
