[PATCH 0/3] improve debug output for EAL flags unit tests

[Bruce Richardson <bruce.richardson@intel.com>]

If issues arise in the EAL flags unit tests they can be trick to debug
due to the lack of debugging output when running recursive instances of
the test binary with different EAL flags. Try to improve this situation
by adding extra debug output for recursive dpdk-test calls in general,
and to some of the EAL flags tests in particular that are proving
problematic.

NOTE: there are intermittent failures seen in github actions with the
file-prefix EAL unit tests. The problems seem less frequent, or possibly
"gone", with this set applied, but even if it masks the problem, this
set does give us greater visibility to debug if they do re-occur.

Bruce Richardson (3):
  app/test: add extra logging for recursive calls
  test/eal_flags: add line numbers to error messages
  test/eal_flags: add extra logging for file prefix tests
