Introduce meta-agl-profile-core and meta-agl-profile-graphics
Rework towards agl profiles. This change is part of a series of changes to create the AGL profiles. This set will mainly introduce the 'core' profile. It is setup to be a drop-in change, thus some files were kept in (dummy) locations for now. However, they'll be taken care of in the next changes in this series. The main target of the meta-agl-profile-core layer is to host: - a minimal, bootable image with network and package management enabled -- agl-image-boot - a minimal image with network and packagemanagement and the AGL APIs -- agl-image-minimal The layer meta-agl-profile-graphical is used as superset of these and includes support for egl+wayland+weston. All recipes concerning graphics were moved there. This is not a full profile as we still have to migrate some parts of meta-agl-demo in a follow-up changeset. The roadmap as discussed during the F2F session in Karlsruhe is: - week 16 : core profile and profiles w/o graphics - week 17 : graphical profiles - week 18 : final conversion of the demo image v2: moved agl-login-manager from -graphics to -core (see Jose's comment) v3: moved back after discussion - follow-up in separate changeset Change-Id: Idacb0d1274baac1f63f8d1b850d4b1104ac33918 Signed-off-by: Jan-Simon Möller <jsmoeller@linuxfoundation.org>

+Subject: [PATCH 5/6] sink-input, volume: Add support for volume ramp factor
+
+Previously, using pa_sink_input_set_volume_ramp() is hard to manage
+if there are several callers. These new volume ramp factor APIs make it
+easy for caller to use and to set more than one volume ramp factor.
+New volume ramp factor will be applied by the multiplication of the other
+ramp factors that have been already set.
+
+APIs are added as below.
+ - pa_sink_input_add_volume_ramp_factor()
+ - pa_sink_input_remove_volume_ramp_factor()
+ - pa_cvolume_ramp_compatible()
+ - pa_sw_cvolume_ramp_multiply()
+ - pa_cvolume_ramp_valid()
