Whether or not overlap regions for self-intersecting polygons
or multiple shapes are filled depends on the operating system graphics,
typeof overlap, and number of overlaps.

intern_strings() now raises a SystemError, rather than calling
Py_FatalError().

intern_string_constants() now reports exceptions to the caller,
rather than ignoring silently exceptions.

_PyCodecRegistry_Init() now reports exceptions to the caller,
rather than calling Py_FatalError().

If the export count is negative, _memory_release() now raises a
SystemError and returns -1, rather than calling Py_FatalError()
which aborts the process.

If PyModule_Create2() is called when the Python import machinery is
not initialized, it now raises a SystemError and returns NULL,
instead of calling Py_FatalError() which aborts the process.

The caller must be prepared to handle NULL anyway.

Fix also umask formatting: use octal prefix.

- Using context managers over multiple lines will only catch the warning from the first line in the context!
- remove a skip for a test that no longer fails on pypy

Use `from ... import ...` to ensure module is fully loaded before accessing its attributes.

collect() should not get an exception, but it does, logging the
exception is enough. Override sys.unraisablehook to decide how to
handle unraisable exceptions.

Py_FatalError() should be avoided whenever possible.
