Implement (optionally versioned) dependencies between layers, and if layer priorities are not specified using BBFILE_PRIORITY_layername (now optional) then work out the layer priority based on dependencies. Define LAYERDEPENDS_layername in layer.conf to specify the dependencies of a layer (list of layer names, split with spaces in the usual way); LAYERVERSION_layername can be defined for each layer allowing specific version dependencies to be specified via depname:version in the list of dependencies. An error will be produced if any dependency is missing or the version numbers do not match exactly (if specified). Note: default priority if unspecified for a layer with no dependencies is lowest defined priority + 1 (or 1 if no priorities are defined). Addresses [YOCTO #790].
