Fix a warning on a race condition on TestWorkerProcess.kill(): ignore
silently ProcessLookupError rather than logging an useless warning.

(cherry picked from commit a661392)
test.regrtest now uses process groups in the multiprocessing mode
(-jN command line option) if process groups are available: if
os.setsid() and os.killpg() functions are available.

(cherry picked from commit ecb035c)
…to ignore (GH-16989)

When building Python in some uncommon platforms there are some known tests that will fail. Right now, the test suite has the ability to ignore entire tests using the -x option and to receive a filter file using the --matchfile filter. The problem with the --matchfile option is that it receives a file with patterns to accept and when you want to ignore a couple of tests and subtests, is too cumbersome to lists ALL tests that are not the ones that you want to accept and he problem with -x is that is not easy to ignore just a subtests that fail and the whole test needs to be ignored.

For these reasons, add a new option to allow to ignore a list of test and subtests for these situations.

(cherry picked from commit e0cd8aa)
Reduce also worker timeout.

cc @pablogsal: I like to have the (almost) same code base for libregrtest in stable branches and master. So I backported your ignore tests feature.

* bpo-37957: Allow regrtest to receive a file with test (and subtests) to ignore (GH-16989)

When building Python in some uncommon platforms there are some known tests that will fail. Right now, the test suite has the ability to ignore entire tests using the -x option and to receive a filter file using the --matchfile filter. The problem with the --matchfile option is that it receives a file with patterns to accept and when you want to ignore a couple of tests and subtests, is too cumbersome to lists ALL tests that are not the ones that you want to accept and he problem with -x is that is not easy to ignore just a subtests that fail and the whole test needs to be ignored.

For these reasons, add a new option to allow to ignore a list of test and subtests for these situations.
