Changpeng 3ff9c13614 NVMe/vfio-user: add initial version vfio-user transport to NVMe driver
When NVMf target linked with vfio-user library, we can use
vfio-user client library to connect to the target.

Here is the three examples that can work with target:

identify -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g
perf -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g -q 1 -o 4096 -w read -t 10
reconnect -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g -q 32 -o 4096 -w randrw \
-M 50 -t 10 -c 0xE

You can run the following test script test/nvmf/target/nvmf_vfio_user.sh to have a quick test,
currently enabled with NVMe Identify,Perf,Reconnect tools.
