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.
