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.

Note that equivalent changes must be made in DPDK's struct rte_pci_addr

c09bfe8965 lib/env: add spdk_unaffinitize_thread
This can be used by threads within SPDK to undo the
affinitization done either by DPDK (for DPDK lcores)
or by inheriting the parent's thread when using
pthread_create().

This will be used by the stub app to unaffinitize
the reactor core to allow the scheduler to flexibly
move it to an idle core.

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.

9f237eac85 env_dpdk: save and restore optind in spdk_env_init
DPDK's use of getopt() needs special handling of the optind global
variable since we are passing it a separate array of arguments (not the
typical argv and argc).  Set optind to 1 internally to env_dpdk so that
the apps don't need to know about it, and restore optind in case the
calling app is also using getopt().

b7349216b9 nvme: optimization for nvme probe and detachment.
remove the unnecessary rte_eal_pci_probe_one() in function
spdk_pci_device_detach(), this could cause error message when we
terminate the application, it will also not make sense try to probe one
device after we detach it, we could call spdk_pci_nvme_device_attach()
instead of spdk_pci_nvme_enumerate() when we have one given device address,
dpdk will try to scan the device and add it back to pci device list then.

lookup that fails to find an allocated map_1gb will always return
SPDK_VTOPHYS_ERROR rather than trying to allocate it and then failing
the lookup anyway.
