WIP patch for a dynamic int_range<>

What I meant is that by using a auto_vec could avoid reimplementing larger
chunks of vec.h/vec.cc for this.
Resizing by adding 10 more ranges can have higher compile time cost than wh=
at
vec.cc (calculate_allocation_1) does - doubles the size each time for small=
er
sizes and and multiplying previous by 3 / 2 for larger ones.=
