5d8c94536a event: hide struct spdk_poller internals
This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).

It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.

5a9fa1d146 test/bdev: move large I/O bdevperf test to nightly
We are already testing bdevperf in the previous 'verify' test, and the
I/O splitting is handled by the NVMe-specific tests, so shorten the bdev
tests somewhat by only doing the large I/O bdevperf test in the nightly
test run.

5627b6871e nvmf: add identify namespace list support to NVMf target
We reported virtualized NVMe devices through NVMe over Fabric specification,
with 1.2.1 NVMe version. For direct mode, the NVMe device maybe has lower
version, such as 1.0, the identify namespace list can not support in those
devices, so we need to add helper function here to simulate such commands
from initiator.

3f80d55199 CONFIG: rename CONFIG_NVMF to CONFIG_RDMA
The NVMf target is being refactored to split the RDMA transport-specific
code into its own file.  Once this is complete, we should be able to
plug in other transports and build the NVMf target without any RDMA
dependency if desired.

To enable this, change the CONFIG option to RDMA; it still controls
whether the whole NVMf target is built for now, but once the RDMA
dependency is actually made optional, we will be able to build the
generic NVMf target code without libibverbs installed.

Previously, we used cap_lo and cap_hi to represent the 32-bit halves of

64-bit structure, and is no less efficient on 64-bit platforms.

Also name the NSSRS field from NVMe 1.2, which was previously reserved.
