Backporting METH_FASTCALL from Python 3.7 (#317)

Browse source 
* 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
