Backporting METH_FASTCALL from Python 3.7 (#317)
* dict copy speedup refer to bpo-31179 or python/cpython@boa7a037b8fde * __build_class__() uses METH_FASTCALL refer python/cpython@69de71b255 refer python/cpython@773dc6dd06 a single test related to __prepare__ fails. * type_prepare uses METH_FASTCALL refer python/cpython@d526cfe546 refer python/cpython@80ab22fa2c the prepare-related test still fails. It's just related to the error message format though. * separate into ParseStack and ParseStackAndKeywords refer python/cpython@6518a93cb1 refer python/cpython@3e1fad6913 refer python/cpython@c0083fc47d * Add _PyArg_NoStackKeywords refer python/cpython@29d39cc8f5 * _PyStack_UnpackDict now returns int refer python/cpython@998c20962c * METH_FASTCALL changes to .inc files done via python's Argument Clinic tool, refer python/cpython@259f0e4437 * Added _PyArg_UnpackStack refer python/cpython@fe54dda08 * Argument Clinic FASTCALL again refer python/cpython@0c4a828ca * Argument Clinic for ordered dictionary object refer python/cpython@b05cbac052 * speed up getargs refer python/cpython@1741441649 * FASTCALL for sorted, next, and getattr refer python/cpython@5a60ecaa7a refer python/cpython@fda6d0acf0 refer python/cpython@84b388bb80 * Optimize methoddescr_call refer python/cpython@2a1b676d1f refer python/cpython@c52572319c refer python/cpython@35ecebe165 refer python/cpython@8128d5a491 * cleanup _PyMethodDef_RawFastCallDict refer python/cpython@0a2e46835d refer python/cpython@98ccba8344 refer python/cpython@c89ef828cf refer python/cpython@250e4b0063 * print now uses METH_FASTCALL refer python/cpython@c3858bd7c6 refer python/cpython@bd584f169f refer python/cpython@06d34393c2 * _struct module now uses Argument Clinic refer python/cpython@3f2d10132d * make deque methods faster refer python/cpython@dd407d5006 * recursive calls in PyObject_Call refer python/cpython@7399a05965 only partially ported, because RawFastCallKeywords hasn't been ported * add macros refer python/cpython@68a001dd59 * all tests pass in MODE=dbg * convert some internal functions to FASTCALL __import__ might need to be changed later, if it is possible to backport the METH_FASTCALL | METH_KEYWORDS flag distinction later. * speed up unpickling refer python/cpython@bee09aecc2 * added _PyMethodDef_RawFastCallKeywords refer python/cpython@7399a05965 * PyCFunction_Call performance refer python/cpython@12c5838dae * avoid PyMethodObject in slots main change in python/cpython@516b98161a test_exceptions changed in python/cpython@331bbe6aaa type_settattro changed in python/cpython@193f7e094f _PyObject_CallFunctionVa changed in python/cpython@fe4ff83049 * fix refcount error found in MODE=dbg all tests now pass in MODE=dbg
