Subject: [PATCH BlueZ v3] mesh: Handle messages sent to a fixed group address

This handles the case when an inbound message is addressed to
a fixed group, i.e., all-proxies, all-friends, all-relays and
all-nodes. The message is delivered to a primary element only,
and, with the exception of all-nodes case, if the corresponding
feature is enabled on the node.
