[Python-Dev] Testing C API

Buildbots have a timeout of 15 min per test. I suggest to use multiple
test_capi_<name>.py files rather than a directory which behaves as a single
test. Or regrtest should be modified to implement timeout differently.

> Currently C API is not completely covered by tests. Tests for particular
parts of C API are scattered through different files. There are files
completely purposed for testing C API (like test_capi.py,
test_getargs2.py), there are classes (usually having "CAPI" in the name) in
different files for testing C API specific for unicode, marshal. Argument
parsing tests are split between two files, test_capi.py, test_getargs2.py.
> I need to add new tests for new features, and I'm going to add new tests
for existing C API. But first I'm going to reorganize tests. Add a new
directory Lib/test/test_capi, and move all C API tests into it, grouped by
function prefixes. test_getargs.py for testing PyArg_*(), test_unicode.py
for testing PyUnicode_*(), etc. Tests that use the _testcapi module, but
don't test specific C API, will left on place.
> The benefit is that it will be easier to run all C API tests at once, and
only them, and it will be clearer what C API is covered by tests. The
disadvantage is that you will need to run several files for testing marshal
for example.
