nvme_ctrlr_process_io_completions() and
nvme_ctrlr_process_admin_completions() now return the number of
completions processed.
This also adds the possibility of returning an error from the
process_*_completions functions (currently unused, but this at least
gets the API ready in case error conditions are added later).

The normal CU_ASSERT_FATAL macro calls a function that is not marked as
noreturn, so static analyzers (e.g. scan-buid) can't figure out that
fatal asserts are really fatal.
Add a wrapper macro that calls abort(), which the analyzer can determine
does not return.

Most devices today support far fewer than 1024, but this is a
more reasonable default upper limit than the spec-defined 64K.

nvme_ctrlr_process_io_completions() now takes a second parameter,
max_completions, to let the user limit the number of I/Os completed on
each poll.
If there are many I/Os waiting to be completed, the
nvme_ctrlr_process_io_completions() function could run for a long time
before returning control to the user, so the max_completions parameter
lets the user have more control of latency.

Set SPDK_ROOT_DIR explicitly in each Makefile so that make from a
subdirectory will work (assuming all dependencies from the upper
directory have already been built). This allows partial rebuilds of the
source tree, as well as building the unit tests without requiring DPDK.

This helps weed out functions that should be static, functions that are
not declared in public header files, and .c files that don't include
their .h interface headers.

Fix all of the uses of __thread so they are at the beginning (similar to
e.g. static).
Don't actually enable -Wold-style-declaration, since clang doesn't
understand that.

nvme_ctrlr_cmd_set_async_event_config() is called from within nvme_ctrlr
but was never stubbed out in its unit test.
