sfxge(4): ensure EvQ poll stops when abort is requested

If an event handler requested an abort, only the inner loop was
guarenteed to be broken out of - the outer loop could continue
if total == batch.

Fix this by poisoning batch to ensure it is different to total.

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

sfxge(4): fix efx_ev_qpoll for non-Siena builds

Both Siena and EF10 use the siena_ev_qpoll() implementation, but this
function is not defined in builds without EFSYS_OPT_SIENA.

Remove siena_ev_qpoll and inline it into efx_ev_qpoll to allow it
to be used in non-Siena builds.

Also remove outdated FIXME comment, as EF10 event batching/merging has
been implemented long ago without needing to modify this code.
