    Allow PLC to function properly when channels use SLIN for audio.
    
    If a channel involved in a bridge was using SLIN audio, then translation
    paths were not guaranteed to be set up properly since in all likelihood
    the number of translation steps was only 1.
    
    This patch enforces the transcode_via_slin behavior if transcode_via_slin
    or generic_plc is enabled and one of the formats to make compatible is
    SLIN.
    
    AST-352
