Rewriting string-extend.
* lib.c (string_extend): Restructure internals with these
goals: no loop: calculate needed space in one step; if the
allocation needs to grow, then grow it by 25% or step it
up to exactly the needed size, whichever of the two is
larger. Overflow check against INT_PTR_MAX, since len and alloc
fields of string are not fixnums but integers extracted
with c_num.
