Making libraries portable where possible.

Many still import (chibi), and as (scheme base) is somewhat more
expensive to load at present these are changed to cond-expand.
Many libraries also rely on (srfi 33), and these have been changed
to a cond-expand first trying (srfi 60) where available.
Also fixing a few portability concerns (duplicate imports of the
same binding), and adding a few libraries missing from lib-tests.scm.
