classes/whitelist: add class to allow whitelisting recipes from a layerpaule/whitelist
Allow restricting recipes brought from a layer to a specified list. This is similar in operation to blacklist.bbclass, but instead specifies a per-layer whitelist of recipes (matched by PN or BPN) that are able to be built from the layer - anything else is skipped. This is potentially useful where you want to bring in a select set of recipes from a larger layer e.g. meta-oe. Implements [YOCTO #8150]. Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com>

+# Class that allows you to restrict the recipes brought from a layer to
+# a specified list. This is similar in operation to blacklist.bbclass
+# but note the difference in how PNWHITELIST is set - we don't use varflags
+# here, the recipe name goes in the value and we use an override for the
+# layer name (although this is not strictly required - you can have one
+# PNWHITELIST value shared by all of the layers specified in
+# PNWHITELIST_LAYERS). The layer name used here is actually the name that
+# gets added to BBFILE_COLLECTIONS in the layer's layer.conf, which may
+# differ from how the layer is otherwise known - e.g. meta-oe uses
+# "openembedded-layer".
+#
+# INHERIT += "whitelist"
+# PNWHITELIST_LAYERS = "layername"
+# PNWHITELIST_layername = "recipe1 recipe2"
+#
+# If you would prefer to set a reason message other than the default, you
+# can do so:
+#
+# PNWHITELIST_REASON_layername = "not supported by ${DISTRO}"
