NVMe opcodes contain a two-bit field that encodes the expected data
direction for each command. Add an enum and a function to extract these
bits.

For those controllers which can support end-to-end data protection
feature, add the support in the driver layer.

This test is only intended to validate functionality, not actual
performance, so one second is plenty.

NVMe reservations provide capabilities that may be used by two or more
hosts to coordinate access to a shared namespace, here we add the 4
reservation commands: reservation register/acquire/release/report.

For the purpose to support different types of input scattered payloads,
such as iovs or scattered list, we define common method in the NVMe
driver, users should implement their own functions to iterate each
segment memory.

The top-level autotest.sh script will catch any core dumps at the end of
the test run, so sprinkling process_core in the individual test scripts
is unnecessary.
Also make the per-component test scripts run with 'set -e' (exit on
error).

Previously, the I/O splitting code and child I/O completion were not
being tested (aside from in the unit tests).
Tweak the I/O size so that it will get split into two child I/Os on
devices with 128 KB striping.
This causes nvme_cb_complete_child() to be exercised, improving code
coverage.

nvme_ut is testing multi-threaded operations, and Valgrind's thread
behavior is different than running the program natively. Under
Valgrind, the unit test essentially hangs waiting for the global
variable to be updated.
