Fixed double free in spdk_rpc_add_portal_group()
spdk_iscsi_portal_create() now takes string arguments as const char* and makes internal copies of them.
This patch also fixes potential memory leak when id == NULL

According to the analysis, the largest name size is
24 not including '\0' (NVMF_RDMA_WRITE_COMPLETE),
so change the the size of name. Also add a check
to avoid the str exceeding our defined name size.

This is the initial commit for "blobfs", a lightweight
filesystem built on top of the SPDK blobstore.
Also included in this patch:
1) a shim for using SPDK bdevs as the backing store for
SPDK blobstore/blobfs
2) documentation for using blobfs as the storage engine
with RocksDB
3) scripts for running a set of workloads and collecting
profiling data with RocksDB and blobfs
See doc/blobfs/getting_started.md included in this commit
for more details on blobfs, including some of the current
limitations.

For an NVMe read, send the completion immediately
following the RDMA WRITE, without waiting for
the acknowledgement. RDMA is strictly ordered,
so the WRITE will arrive before the completion.

Except for a CONNECT capsule, always use the central data
pool for RDMA READ/WRITE operations. The in-capsule
data buffer is associated with the receive operation
while the pool data buffers are associated with the
completion, and using the in-capsule data buffer
causes a lifetime mismatch.

The RDMA protocol this module uses is strictly ordered,
which means messages are delivered in exactly the order
they are sent. However, we have detected a number of
cases where the acknowledgements for those messages
arrive out of order. This patch attempts to handle
that case.
Separate the data required to post a recv from the
data required to send a response. If a recv arrives
when no response object is available, queue the
recv.

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.
