Fix error check on mmap(2)
It should check MAP_FAILED instead of NULL for error.
On mmap(2) man page:
RETURN VALUE
On success, mmap() returns a pointer to the mapped area.
On error, the value MAP_FAILED (that is, (void *) -1) is
returned, and errno is set to indicate the error.
Replace most of calls of _PyErr_WriteUnraisableMsg() and some
calls of PyErr_WriteUnraisable(NULL) with PyErr_FormatUnraisable().

Move the private _PyErr_WriteUnraisableMsg() functions to the
internal C API (pycore_pyerrors.h).
Move write_unraisable_exc() from _testcapi to _testinternalcapi.
* Add table describing possible executable classes for out-of-process debuggers.
* Remove shim code object creation code as it is no longer needed.
* Make lltrace a bit more robust w.r.t. non-standard frames.
