tests: Silence various error messages and warnings.

This silences glib warnings which are due to testing
of error handling, deprecation warnings which we ignore
since we want to continue testing deprecated code and
other error output of code which is supposed to fail.

To reduce code duplication and make things easier
this introduces a shared helper module containing
various context managers and decorators which allow
testing and silencing of warnings and errors.
