Subject: BACKENDS: Add OSystem::getDefaultConfigFileName

This is used to provide default implementations for createConfigWriteStream
and createConfigReadStream, which can be used by most backends.

Note that backends can still override createConfigRead/WriteStream;
this could be useful if settings on some port are not stored in a
regular file (think 'Windows registry', for a hypothetical example).
