…H-16607) (GH-19728)

Adds a short description of `PyDoc_STRVAR` and `PyDoc_STR` to "Useful macros" section of C-API docs.

Currently, there is [one lone mention](https://docs.python.org/3/c-api/module.html?highlight=pydoc_strvarGH-c.PyModuleDef) in the C-API reference, despite the fact that `PyDoc_STRVAR` is ubiquitous to `Modules/`.

Additionally, this properly uses `c:macro` within `Doc/c-api/module.rst` to link..

It is possible to use either '-isysroot /some/path' (with a space) or
'-isysroot/some/path' (no space in between). Support both forms in
places where special handling of -isysroot is done, rather than just
the first form.

Fixes Issue39285

The example incorrectly returned True for match.

Furthermore the example is ambiguous in its usage of PureWindowsPath.
Windows is case-insensitve, however the underlying match functionality
utilizes fnmatch.fnmatchcase.

* bpo-38502: regrtest uses process groups if available (GH-16829)

test.regrtest now uses process groups in the multiprocessing mode

* 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.
