While I think that pdb++ should be fixed in this regard (by using
`pdb.Pdb`, and not `self.__class__` maybe), this ensures that custom
debuggers like this are working.
Regarding tests: it merges ``test_pdb_interaction``,
``test_pdb_print_captured_stdout``, and
``test_pdb_print_captured_stderr`` into
``test_pdb_print_captured_stdout_and_stderr`` (clarity and performance,
especially since pexpect tests are slow).
This handles `header` similar to Python 3.7 does it, and forwards any
other keyword arguments to the Pdb constructor.
This allows for `__import__("pdb").set_trace(skip=["foo.*"])`.
Fixes https://github.com/pytest-dev/pytest/issues/4416.
To keep existing tests which emit RemovedInPytest4Warnings running, decided
to go with a command line option because:
* Is harder to integrate an ini option with tests which already use an ini file
* It also marks tests which need to be removed/updated in 4.1, when
RemovedInPytest4Warning and related functionality are removed.
Fix#3737
This is relevant when using runpytest in-process.
Fixes:

After `pdb.set_trace()` capturing is turned off.
This patch resumes it after using the `continue` (or `c` / `cont`)
command.
Store _pytest_capman on the class, for pdbpp's do_debug hack to keep it.
Without this, `debug …` would fail like this:

- add pytest_leave_pdb hook
- fixes test_pdb_interaction_capturing_twice: would fail on master now,
but works here
`help quit` in pdb says:
> Quit from the debugger. The program being executed is aborted.
But pytest would continue with the next tests, often making it necessary
to kill the pytest process when using `--pdb` and trying to cancel the
tests using `KeyboardInterrupt` / `Ctrl-C`.
This gets printed by the terminal reporter already, and currently
results in the same error being displayed twice, e.g. when raising an
`Exception` manually from `pytest.debugging.pytest_exception_interact`.
`expect()` expects an regular expression, so "Pdb" is equivalent to
"(Pdb)".
But instead of escaping the parenthesis this patch removes them, to
allow for matching "(Pdb++)", too.
