Address review: one powers-of-ten table, literal sizes from the type

Browse Source 
- dtoa_impl::powers_of_ten() (10^0 to 10^19, one entry per line)
  replaces powers_of_ten_16() and the table of int_pow10()
- put_literal() takes the length of a string literal from its type
- small_stack holds the heap vector by reference
- the growth step of the output buffer is written in hex
