[issue29367] python-gdb: display wrapper_call()

[STINNER Victor]

New submission from STINNER Victor:

python-gdb.py handles various Python calls, but not descriptors. Attached patch 
adds code to display calls to wrapperobject objects.

The patch adds the first "" line of the traceback:
---
(gdb) py-bt
Traceback (most recent call first):
  
  File "/home/haypo/prog/python/git_cpython/Lib/encodings/utf_8.py", line 41, 
in getregentry
streamwriter=StreamWriter,
  File "/home/haypo/prog/python/git_cpython/Lib/encodings/__init__.py", line 
122, in search_function
entry = getregentry()
---

I wrote this patch while working on the issue #29358. Object instanciation is 
full of wrappers. A better debugger helps to me understand my bugs ;-)

Example to get such tracecback:
---
haypo@selma$ gdb -args ./python -m test -v test_sys
(gdb) b wrapper_call
(gdb) run
(gdb) py-bt
Traceback (most recent call first):
  
  File "/home/haypo/prog/python/default/Lib/enum.py", line 66, in __init__
super().__init__()
  File "/home/haypo/prog/python/default/Lib/enum.py", line 117, in __prepare__
enum_dict = _EnumDict()
  
  File "/home/haypo/prog/python/default/Lib/enum.py", line 509, in 
class Enum(metaclass=EnumMeta):
  
  File "", line 205, in _call_with_frames_removed
  (...)
---

I guess that the next step is to write a test ;-)
