maths: use mult rather than negation in constexpr
...
util::digits was triggering signed overflow warnings under gcc. By using
negative multiplication rather than explicit negation we get the same
behaviour, sans warning.

specification. does not implement 'n' or '$' specifiers. falls back to

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.
