258845450d env: deprecate spdk_pci_get_device()
This isn't possible to implement using the current public API of DPDK,
and all of the in-tree users have been removed.  Replace the
implementation with a stub that always returns NULL and mark it
deprecated so that any users have a release to update their code.

07526d85ef env/dpdk: use MEMPOOL_F_NO_PHYS_CONTIG
This is required for DPDK's single file segments.
Without this flag, mempools are likely to fail to

contiguity anywhere in SPDK and a quick NVMe+UIO

17d55c9fd4 bdev/virtio: added vhost-blk initiator
Briefly tested with SPDK target via bdevio
through both vhost-user and QEMU's virtio-pci.

vhost-blk driver is not mentioned in any doc yet.
A virtio-blk bdev can be created as following:

`construct_virtio_user_blk_bdev /tmp/virtio.0 MyVirtioBlk0 --vq-count 16`
`construct_virtio_pci_blk_bdev 0000:01:00.0 MyVirtioBlk1`

or

```
[VirtioUser0]
  Path /tmp/vhost.0
  Type Blk
  Queues 16

[VirtioPci]
  Enable Yes
```

If `Type` field is not present, the VirtioUser
section will be parsed as a SCSI one, preserving
backward compatibility.

601bcbcf66 util: extend cpumask to hold more than 64 cpus
Fixes github issue #218.

This patch introduces spdk_cpuset object to store and manipulate
the set of individual CPUs. The main objective of this object is
to replace cpumask declared as uint64_t and extend the limitation
of supported CPUs (lcores) above 64 CPUs.

spdk_cpuset is always allocated dynamically and accessed by opaque
pointer, what makes it easier to extend in the future without
breaking API/ABI.

This patch also extends parsing function allowing to set cpumask
using a list of cpus e.g. "[0-4,10,12]" sets mask of 0,1,2,3,4,10,12
as well as hexadecimal string with and without "0x" prefix.

479134e9d4 vtophys: remap vfio dma memory when necessary
VFIO requires at least one IOMMU group to be added to the
VFIO container to be able to perform any IOMMU operations
on that container. [1] Without any groups added, VFIO_IOMMU_MAP_DMA
would always respond with errno 22 (Invalid argument).

Also, if the last IOMMU group is removed from the container
(device hotremove), all the IOMMU mappings are lost.

In both cases we need to remap vfio memory as soon as the
first IOMMU group is attached. The attach is done inside
DPDK during device attach and we can't hook into it directly.
Instead, this patch hooks into our PCI init/fini callbacks.
There's now a PCI device ref counter in our vfio manager and
a history of all registered memory pages. When the refcount
is increased from 0 to 1, the vtophys will remap all vfio
dma memory.

[1] https://www.kernel.org/doc/Documentation/vfio.txt
"On its own, the container provides little functionality,
with all but a couple version and extension query interfaces
locked away. The user needs to add a group into the container
for the next level of functionality.  [...] With a group
(or groups) attached to a container, the remaining ioctls
become available, enabling access to the VFIO IOMMU
interfaces."

f62a37b22f env_dpdk: use detected include file path
env.mk already detects the location of the include path (which may or
may not have 'dpdk' in the name depending on the DPDK version), so put
that into a DPDK_INC_DIR variable and use it in the libnuma check so we
find the correct rte_config.h location.

Also check if rte_config.h exists before trying to pass it to grep -
this prevents error messages when running 'make clean' using the dpdk
submodule, because the rte_config.h file is removed before the other
SPDK directories get a chance to run 'make clean'.

3860fa7ef6 env: Search DPDK memsegs before /proc/self/pagemap for phys addrs
When running IOMMU enabled the user is actually
interacting with IO addresses - not physical
addresses. The value in the DPDK memseg array is
the correct one in this case, and should be used
at a higher priority than attempting to look up
the address in /proc/self/pagemap (i.e. what
rte_mem_virt2phy() does).

Further, rte_mem_virt2phy() will always fail when
running as an unprivileged user, but scanning
the memory segments will work.

c588baab29 reactor: add pid to names for rings and mempools
This is required for using the event framework
in multi-process mode since they must be unique
across the group of processes..

Currently the stub app calls into the env layer
directly, bypassing the event framework, so this
issue would only be seen with multiple secondary
processes using the app framework.  Some future
changes will change the stub app to use the event
framework which necessitates this change immediately.
