bpo-40280: Skip socket, fork, subprocess tests on Emscripten (GH-31986)
- Add requires_fork and requires_subprocess to more tests
- Skip extension import tests if dlopen is not available
- Don't assume that _testcapi is a shared extension
- Skip a lot of socket tests that don't work on Emscripten
- Skip mmap tests, mmap emulation is incomplete
- venv does not work yet
- Cannot get libc from executable

The "entire" test suite is now passing on Emscripten with EMSDK from git head (91 suites are skipped).

bpo-26131: Deprecate usage of load_module() (GH-23469)
Raise an ImportWarning when the import system falls back on load_module(). As for implementations of load_module(), raise a DeprecationWarning.

bpo-39824: module_traverse() don't call m_traverse if md_state=NULL (GH-18738)
Extension modules: m_traverse, m_clear and m_free functions of
PyModuleDef are no longer called if the module state was requested
but is not allocated yet. This is the case immediately after the
module is created and before the module is executed (Py_mod_exec
function). More precisely, these functions are not called if m_size is
greater than 0 and the module state (as returned by
PyModule_GetState()) is NULL.

Extension modules without module state (m_size <= 0) are not affected.

bpo-33629: Prevent coredump in test_importlib (GH-7090)
bpo-32374, bpo-33629: Use support.SuppressCrashReport() in
test_bad_traverse() of MultiPhaseExtensionModuleTests to prevent
leaking a core dump file.

Marcel Plch c2b0b12d1a bpo-32374: m_traverse may be called with m_state=NULL (GH-5140)
Multi-phase initialized modules allow m_traverse to be called while the
module is still being initialized, so module authors may need to account
for that.

Nick Coghlan 8682f578c1 Issue #27782: Fix m_methods handling in multiphase init
Multi-phase extension module import now correctly allows the
``m_methods`` field to be used to add module level functions
to instances of non-module types returned from ``Py_create_mod``.

Patch by Xiang Zhang.

Nick Coghlan d5cacbb1d9 PEP 489: Multi-phase extension module initialization
Known limitations of the current implementation:

- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet

The leak is most visible by running:

  ./python -m test -R3:3 test_importlib

However, you can also see it by running:

  ./python -X showrefcount

Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.

Brett Cannon d2476c6e4b Issue #19698: Remove exec_module() from the built-in and extension
module loaders.

Due to the fact that the call signatures for extension modules and
built-in modules does not allow for the specifying of what module to
initialize and that on Windows all extension modules are built-in
modules, work to clean up built-in and extension module initialization
will have to wait until Python 3.5. Because of this the semantics of
exec_module() would be incorrect, so removing the methods for now is
the best option; load_module() is still used as a fallback by
importlib and so this won't affect semantics.

Brett Cannon 45a5e3afe5 Issue #15168: Move importlb.test to test.test_importlib.
This should make the Linux distros happy as it is now easier to leave
importlib's tests out of their base Python distribution.
