mp.c: Export `implicitmp' and `implicitgf'.

The next few commits are going to be about shoring up implicit
conversions in generic arithmetic operators, and, in particular, in
forbidding obviously silly conversions, e.g., from floating-point
numbers of strings to integers or polynomials.  This is a first step
towards that.

No new callers yet, and no functional change.
