Heh. Thanks Rasmus. I didn't remember that one.

I think the 'int str_has_prefix' naming and returning the prefix
length may be a bit better use than 'bool strstarts' and perhaps a
treewide conversion of the existing strstarts to str_has_prefix
would be OK as there aren't that many.

$ git grep -w strstarts | wc -l
