bpo-32030: Split Py_Main() into subfunctions (#4399) * Don't use "Python runtime" anymore to parse command line options or to get environment variables: pymain_init() is now a strict separation. * Use an error message rather than "crashing" directly with Py_FatalError(). Limit the number of calls to Py_FatalError(). It prepares the code to handle errors more nicely later. * Warnings options (-W, PYTHONWARNINGS) and "XOptions" (-X) are now only added to the sys module once Python core is properly initialized. * _PyMain is now the well identified owner of some important strings like: warnings options, XOptions, and the "program name". The program name string is now properly freed at exit. pymain_free() is now responsible to free the "command" string. * Rename most methods in Modules/main.c to use a "pymain_" prefix to avoid conflits and ease debug. * Replace _Py_CommandLineDetails_INIT with memset(0) * Reorder a lot of code to fix the initialization ordering. For example, initializing standard streams now comes before parsing PYTHONWARNINGS. * Py_Main() now handles errors when adding warnings options and XOptions. * Add _PyMem_GetDefaultRawAllocator() private function. * Cleanup _PyMem_Initialize(): remove useless global constants: move them into _PyMem_Initialize(). * Call _PyRuntime_Initialize() as soon as possible: _PyRuntime_Initialize() now returns an error message on failure. * Add _PyInitError structure and following macros: * _Py_INIT_OK() * _Py_INIT_ERR(msg) * _Py_INIT_USER_ERR(msg): "user" error, don't abort() in that case * _Py_INIT_FAILED(err)

Mass checkin (more to follow for other directories). Introduce truly separate (sub)interpreter objects. For now, these must be used by separate threads, created from C. See Demo/pysvr for an example of how to use this. This also rationalizes Python's initialization and finalization behavior: Py_Initialize() -- initialize the whole interpreter Py_Finalize() -- finalize the whole interpreter tstate = Py_NewInterpreter() -- create a new (sub)interpreter Py_EndInterpreter(tstate) -- delete a new (sub)interpreter There are also new interfaces relating to threads and the interpreter lock, which can be used to create new threads, and sometimes have to be used to manipulate the interpreter lock when creating or deleting sub-interpreters. These are only defined when WITH_THREAD is defined: PyEval_AcquireLock() -- acquire the interpreter lock PyEval_ReleaseLock() -- release the interpreter lock PyEval_AcquireThread(tstate) -- acquire the lock and make the thread current PyEval_ReleaseThread(tstate) -- release the lock and make NULL current Other administrative changes: - The header file bltinmodule.h is deleted. - The init functions for Import, Sys and Builtin are now internal and declared in pythonrun.h. - Py_Setup() and Py_Cleanup() are no longer declared. - The interpreter state and thread state structures are now linked together in a chain (the chain of interpreters is a static variable in pythonrun.c). - Some members of the interpreter and thread structures have new, shorter, more consistent, names. - Added declarations for _PyImport_{Find,Fixup}Extension() to import.h.
