Some rearrangements for the importdl.c restructuring. This is part of a set of patches by Greg Stein.

Lots of changes, most minor (fatal() instead of abort(), use of err_fetch/err_restore and so on). But... NOTE: import.c has been rewritten and all the DL stuff is now in the new file importdl.c.

Issue #13959: Re-implement imp.get_suffixes() in Lib/imp.py. This introduces a new function, imp.extension_suffixes(), which is currently undocumented. That is forthcoming once issue #14657 is resolved and how to expose file suffixes is decided.

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.

Removed some variables that are used to exchange data between import.c and importdl.c: the MAXSUFFIXSIZE macro is now defined in importdl.h, and the modules dictionary is now passed using PyImport_GetModuleDict(). Also undefine USE_SHLIB for AIX -- in AIX 4.2 and up, dlfcn.h exists but we don't want to use it.

For Windows, need to add #include <windows.h>.
