closes bpo-42030: Remove legacy AIX dynload support (GH-22717)
Since c19c5a6, AIX builds have defaulted to using dynload_shlib over dynload_aix when dlopen is available. This function has been available since AIX 4.3, which went out of support in 2003, the same year the previously referenced commit was made. It has been nearly 20 years since a version of AIX has been supported which has not used dynload_shlib so there's no reason to keep this legacy code around.

bpo-41894: Fix UnicodeDecodeError while loading native module (GH-22466)
When running in a non-UTF-8 locale, if an error occurs while importing a native Python module (say because a dependent share library is missing), the error message string returned may contain non-ASCII code points causing a UnicodeDecodeError. PyUnicode_DecodeFSDefault is used for buffers which may contain filesystem paths. For consistency with os.strerror(), PyUnicode_DecodeLocale is used for buffers which contain system error messages. While the shortname parameter is always encoded in ASCII according to PEP 489, it is left decoded using PyUnicode_FromString to minimize the changes and since it should not affect the decoding (albeit _potentially_ slower). In dynload_hpux, since the error buffer contains a message generated from a static ASCII string and the module filesystem path, PyUnicode_DecodeFSDefault is used instead of PyUnicode_DecodeLocale as is used elsewhere. * bpo-41894: Fix bugs in dynload error msg handling For both dynload_aix and dynload_hpux, properly handle the possibility that decoding strings may return NULL and when such an error happens, properly decrement any previously decoded strings and return early. In addition, in dynload_aix, ensure that we pass the decoded string *object* pathname_ob to PyErr_SetImportError instead of the original pathname buffer.

bpo-40422: Move _Py_closerange to fileutils.c (GH-22680)
This API is relatively lightweight and organizationally, given that it's used by multiple modules, it makes sense to move it to fileutils. Requires making sure that _posixsubprocess is compiled with the appropriate Py_BUIILD_CORE_BUILTIN macro.
