Setting log_level via the CLI or .ini will control the log level of the
report that is dumped upon failure of a test.
If caplog modified the log level during the execution of that test, it
should not impact the level that is displayed upon failure in the
"captured log report" section.

ran:
- rebased
- reused handler
- changed store keys also to "caplog_handler_*"
- added changelog
all bugs are mine :)

Currently, a bad logging call, e.g.
logger.info('oops', 'first', 2)
triggers the default logging handling, which is printing an error to
stderr but otherwise continuing.
For regular programs this behavior makes sense, a bad log message
shouldn't take down the program. But during tests, it is better not to
skip over such mistakes, but propagate them to the user.
Previously, a LoggingCaptureHandler was instantiated for each test's
setup/call/teardown which turns out to be expensive.
Instead, only keep one instance and reset it between runs.
The logstart/logreport/logfinish hooks don't need the stuff in
_runtest_for. The test capturing catching_logs call is irrelevant for
them, and the item-conditional sections are gone.
- Instead of making it optional, always set up a handler, but possibly
going to /dev/null. This simplifies the code by removing a lot of
conditionals. It also can replace the NullHandler() we already add.
- Change `set_log_path` to just change the stream, instead of recreating
one. Besides plugging a resource leak, it enables the next item.
- Remove the capturing_logs from _runtest_for, since it sufficiently
covered by the one in pytest_runtestloop now, which wraps all other
_runtest_for calls.
The first item alone would have had an adverse performance impact, but
the last item removes it.
Remove usage of `@contextmanager` as it is a bit slower than
hand-rolling, and also disallows re-entry which we want to use.
Removing protections around addHandler()/removeHandler(), because
logging already checks that internally.
Conceptually it doesn't check per catching_logs (and catching_logs
doesn't restore the older one either). It is just something that is
defined for each handler once.
