Merge branch 'rs/qsort'

We call "qsort(array, nelem, sizeof(array[0]), fn)", and most of
the time third parameter is redundant.  A new QSORT() macro lets us
omit it.

* rs/qsort:
  show-branch: use QSORT
  use QSORT, part 2
  coccicheck: use --all-includes by default
  remove unnecessary check before QSORT
  use QSORT
  add QSORT
