Make sys.setprofile() and sys.settrace() functions reentrant. They
can no long fail with: RuntimeError("Cannot install a trace function
while another trace function is being installed").
Make _PyEval_SetTrace() and _PyEval_SetProfile() functions reentrant,
rather than detecting and rejecting reentrant calls. Only delete the
reference to function arguments once the new function is fully set,
when a reentrant call is safe. Call also _PySys_Audit() earlier.
It adds a missing testcase for bpo-34125. This is testing code which is
affected by PEP 590, so missing this test might accidentally break
CPython if we screw up with implementing PEP 590.
`list.append([], None)` was profiled but `list.append([], None, **{})` was not profiled.
Enable profiling for later case.

I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux. The only differences I found were actually tests
that were previously *not* run.
