* bpo-31324: Optimize support._match_test() (#4421) * Rename support._match_test() to support.match_test(): make it public * Remove support.match_tests global variable. It is replaced with a new support.set_match_tests() function, so match_test() doesn't have to check each time if patterns were modified. * Rewrite match_test(): use different code paths depending on the kind of patterns for best performances.

This function is written for debug purpose only, to dump the traceback in
the worst case: after a segmentation fault, at fatal error, etc. That's why,
it is very limited. Strings are truncated to 100 characters and encoded to
ASCII with backslashreplace. It doesn't write the source code, only the
function name, filename and line number of each frame. Write only the first
100 frames: if the traceback is truncated, write the line " ...".

This function is written for debug purpose only. It calls
_Py_DumpTraceback() for each thread, and so has the same limitations. It
only write the traceback of the first 100 threads: write "..." if there are
more threads.
If current_tstate is NULL, the function tries to get the Python thread state
of the current thread. It is not an error if the function is unable to get
the current Python thread state.
If interp is NULL, the function tries to get the interpreter state from
the current Python thread state, or from
_PyGILState_GetInterpreterStateUnsafe() in last resort.
It is better to pass NULL to interp and current_tstate, the function tries
different options to retrieve these informations.
