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.

v2:
* set affinity to master core if no core is off, as suggested by
  Anatoly

Olivier Matz (4):
  eal: use sizeof to avoid a double use of a define
  eal: new function to create control threads
  eal: set name when creating a control thread
  eal: set affinity for control threads
