libobs: Allow filter processing function to return false

Browse Source 
(Note: this commit also modifies the obs-filters and test-input modules)

Changes the obs_source_process_filter_begin return type so that it
returns true/false to indicate that filter processing should or should
not continue (for example if the filter is bypassed or if there's some
other sort of issue that causes the filtering to fail)
