[arm-allstar] Updated source code

[Richard Bateman]

Is there a way to get updated source code? First I'm having a lot of issues
with my repeater and I'm wondering how much could be related to bugs that
are already fixed.

In particular I'm having some intermod issues and also what seems like an
audio feedback problem; I seem to remember seeing something about an echo
or feedback issue awhile back. I'm using a raspberry pi 3 so the image I
put on them is somewhat old.

I'm a fairly experienced linux user so I don't expect any trouble updating
the code and rebuilding even if I have to jump through some hoops. I'd like
to dig into the code eventually as well, but I'd rather not be tracking
down issues that are already fixed.
