MacOSX/Framework: Properly convert libvlc Exception to NSException. Rename quit_on_exception to catch_exception.

Limit the mouse-x and mouse-y beetween 0 and p_vout->fmt_in.i_visible_(width\|height) to avoid unsigned overflow. Feel free to revert if this commit is stupid.

Revert [19071] because it is broken. It doesn't allow channel or samplerate changes for fourcc mp4a even when explicitly requested by the user. Specify channels=2 and samplerate=NNNN for fourcc mp4a if you want AAC SBR.

Use id->p_decoder->fmt_out as input for id->p_encoder->fmt_in. Removes double initialisation of id->p_encoder->fmt_in (es_format_Init()).
