New APIs `spdk_dif_update_crc32c` and `spdk_dif_update_crc32c_stream` have been

added to compute CRC-32C checksum for extended LBA payload.

New Fibre Channel transport for NVMe over Fabrics target. Requires an FC HBA to use.

A new API `spdk_mempool_lookup` has been added to lookup the memory pool created

by the primary process.



Added spdk_pci_get_first_device() and spdk_pci_get_next_device() to allow

iterating over PCI devices detected by SPDK. Because of this, all SPDK APIs

to attach/detach PCI devices are no longer thread safe. They are now meant to

be called from only a single thread only, the same only that called spdk_env_init().

This applies to the newly added APIs as well.



### sock

Added nvmf_get_stats RPC method to retrieve NVMf susbsystem statistics.



Response buffers for RPC requests are now always pre-allocated, which implies

that all spdk_jsonrpc_begin_result() calls always succeed and return a valid

buffer for JSON response. RPC calls no longer need to check if the buffer is

non-NULL.



Added SPDK_RPC_REGISTER_ALIAS_DEPRECATED to help with deprecation process when

renaming existing RPC. First time a deprecated alias is used, it will print

a warning message.



RPC `get_rpc_methods` was renamed `rpc_get_methods`. The old name is still usable,

but is now deprecated.



### blobstore



A snapshot can now be deleted if there is only a single clone on top of it.



### build



Cross compilation is now supported with an extra configure option:

`./configure --target-arch=aarm64`



Additionally, a prefix to the toolchain can be provided to automatically set up

CC and CXX:

`./configure --target-arch=aarm64 --cross-prefix=aarch64-linux-gnu`



### vhost



By default, SPDK will now rely on upstream DPDK's rte_vhost instead of its fork

located inside SPDK repo. The internal fork is still kept around to support older

DPDK versions, but is considered legacy and will be eventually removed.



`configure` will now automatically use the upstream rte_vhost if the used DPDK

version is >= 19.05.



spdk_vhost_init() is now asynchronous and accepts a completion callback.



## v19.04:
