[dpdk-dev] [RFC 0/4] new function to create control threads

[Olivier Matz]

This patchset targets 18.05.
It applies on top of 17.11 + [1] and [2].

Some parts of dpdk use their own management threads. Most of the time,
the affinity of the thread is not properly set: it should not be scheduled
on the dataplane cores, because interrupting them can cause packet losses.

This patchset introduces a new wrapper for thread creation that does
the job automatically, avoiding code duplication.
