Using operator-= when the rhs is a negative value is equivalent
to using += on -rhs. This is fixing rounding in that scenario.

This patch is fixing CircularQueue iterators' subtraction, in particular
the behaviour when head and tail round multiple times.

The former implementation of CircleBuf is functional but a bit too
tailored to match a use-case. This patches introduces a new iterable
circular queue, which adds some more functionality so it can also be
used for the newer LSQ implementation, where iteration and iterators
are a very desirable feature.
