* bpo-37931: Fix crash on OSX re-initializing os.environ (GH-15428)Miss Islington (bot)2019-12-061-5/+5
| | | | | | | | | | | | | On most platforms, the `environ` symbol is accessible everywhere. In a dylib on OSX, it's not easily accessible, you need to find it with _NSGetEnviron. The code was caching the *value* of environ. But a setenv() can change the value, leaving garbage at the old value. Fix: don't cache the value of environ, just read it every time.

* bpo-38634: Allow non-apple build to cope with libedit (GH-16986)Miss Islington (bot)2019-12-041-19/+4
| | | | | | | | | | | | | | The readline module now detects if Python is linked to libedit at runtime on all platforms. Previously, the check was only done on macOS. If Python is used as a library by a binary linking to libedit, the linker resolves the rl_initialize symbol required by the readline module against libedit instead of libreadline, which leads to a segfault. Take advantage of the existing supporting code to have readline module being compatible with both situations.

Instead, add a new _Py_dll_path global variable. Remove _PyConfig_SetPathConfig(): replaced with _PyPathConfig_Init(). Py_Initialize() now longer sets the "global path configuration", but only initialize _Py_dll_path.
