This patch adds basic ratelimiting to sending out AckPackets
and non AckPackets. This provides a basic way to prevent
aprsd from sending out packets as fast as possible, which isn't
great for a bandwidth limited network.
This patch also adds some keepalive checks to all threads in the
threadslist as well as the network client objects (apris, kiss)
This patch reworks all the packet processing to use the new
Packets objects. Nuked all of the messaging classes.
backwards incompatible changes
all messaging.py classes are now gone and replaced by
packets.py classes
This patch updates the main aprsd threads class to use
a shared queue to notify all aprsd thread classes they need
to exit. This ensures any closing down of sockets, etc happens from
inside the context of the thread itself, not the MainThread that
calls stop.
This patch creates a threads directory and separates out
the contents of threads.py into separate files in the
threads directory to make it easier to find and maintain.
