maths: make sign query inline
...
code which needs this function tends to require a fairly simple
implementation inline for the optimiser to reach more successfully. we
tended to generate function calls to this which slowed this inner loops.

remove annotations header
...
The annotations were never particularly robust, and weren't used in many
locations (or consistently). And we should be migrating to c++14
annotation syntax anyway. By focusing on writing them all locally we
will be a little more standards compliant, and the attributes should be
more visible.
