[PATCH 1/6] bitmap_parselist: don't calculate length of the input string

[Yury Norov]

bitmap_parselist() calculates length of the input string before passing
it to the __bitmap_parselist(). But the end-of-line condition is checked
for every character in __bitmap_parselist() anyway. So doing it in wrapper
is a simple waste of time.
