The gdb hooks for debugging CPython (within Tools/gdb) have
been enhanced to show information on more C frames relevant to CPython within
the "py-bt" and "py-bt-full" commands:
* C frames that are waiting on the GIL
* C frames that are garbage-collecting
* C frames that are due to the invocation of a PyCFunction
the Python traceback if Python is optimized.
* delay the lookup of the size_t type, it is not available at startup
* The second argument of the PyFrameObjectPtr constructor is optional, as
done in other constructors
* iter_builtins() and iter_globals() methods of PyFrameObjectPtr returns
an empty tuple instead of None if Python is optimized
* Fix py-bt and py-bt-full to handle correctly "optimized" frames
* Frame.get_pyop() tries to get the frame pointer from PyEval_EvalCodeEx()
if the pointer is optimized out in PyEval_EvalFrameEx()
traceback if Python is optimized.

Encode unicode strings to the terminal encoding with backslashreplace error (as
Python does for sys.stderr) before writing them to sys.stdout. It fixes
UnicodeEncodeError on writing non-ascii characters in an ascii terminal (C
locale: ASCII encoding).
* Escape non printable characters (use locale.getpreferredencoding())
* Fix support of surrogate pairs
* test_gdb.py: use ascii() instead of repr() in gdb program arguments to avoid
encoding issues
* Fix test_strings() of test_gdb.py for encoding different than UTF-8
(eg. ACSII)
