Use fixnum indices for vector iteration.

* lib.c (find, rfind, find_max, find_if, rfind_if, pos, rpos,
pos_if, rpos_if, pos_max): Consistently fixnum indices for
iterating over vector. In some functions, a cnum is already
used, but could be out of fixnum range; we switch to using
c_fixnum for extracting the length and then num_fast on the
index. Some functions are converted from using a val index.
In the case of rfind_if, a bug is fixed: it was using plusp,
which now becomes the correct >= 0.
