afef2104a5 test/unit/lib/idxd: Add unit test stubs
With some build environments (e.g. clang, see #1613) linking fails with
unresolved references. This is caused by the inclusion of 'unused code'
which is usually discarded by the linker. The 'unused code' contains
references to functions that have not been 'stubbed' out. The failure
can be seen by removing 'LDFLAGS += -Wl,--gc-sections' in
spdk.unittest.mk

Resolved by adding stubs for missing references. These are never called
so return an arbtrary default value.

Move include of idxd/idxd.c after definition of movdir64b so that mock
function is used.

Part of a set of independent changes which
Fixes #1613

33eac886b9 lib/idxd: refactor batching for increased performance
And to eliminate an artificial constraint on # of user descriptors.
The main idea here was to move from a single ring that covered all
user descriptors to a pre-allocated ring per pre-allocated batch.

In addition, the other major change here is in how we poll for
completions.  We used to poll the batch rings then the main ring.
Now when commands are prepared their completion address is added to
a per channel list and the poller simply runs through that list
not caring which ring the completion address belongs too. This
simplifies the completion logic considerably and will avoid
polling locations that can't potentially have a completion.

Some minor rework was included as well, mainly getting rid of the
ring_ctrl struct as it didn't serve much of a purpose anyway and
with how things are setup now its easier to read with all the
elements in the channel struct.

Also, a change that came in while this was WIP needed a few fixes
to function correctly.  Addressed those and moved them to a
helper function so we have one point of control for xlations.

Added support for NOP in cases where a batch is submitted with
only 1 descriptor.
