To avoid Guile module dependency cycles, inherited packages must be defined in the same module. Use this opportunity to simplify the patches applying mechanism, versioning custom patches the same as for other packages. * gnu/packages/patches/ffmpeg-jami-change-RTCP-ratio.patch: New file. * gnu/packages/patches/ffmpeg-jami-rtp_ext_abs_send_time.patch: Likewise. * gnu/packages/patches/ffmpeg-jami-libopusdec-enable-FEC.patch: Likewise. * gnu/packages/patches/ffmpeg-jami-libopusenc-enable-FEC.patch: Likewise. * gnu/packages/patches/ffmpeg-jami-libopusenc-reload-packet-loss-at-encode.patch: Likewise. * gnu/packages/patches/ffmpeg-jami-remove-mjpeg-log.patch: Likewise. * gnu/packages/patches/ffmpeg-jami-screen-sharing-x11-fix.patch: Likewise. * gnu/local.mk (dist_patch_DATA): Register them. * gnu/packages/jami.scm (jami-apply-custom-patches): Delete procedure. (%ffmpeg-default-configure-flags): Delete variable. (ffmpeg-compose-configure-flags): Delete procedure. (ffmpeg-jami): Move to... * gnu/packages/video.scm (ffmpeg-jami): ... here. Apply patches to origin and repatriate configure flags. Change-Id: Id374fae18240cd76b224915d80b61422635ccb77
