API:  Change cpdefs -> cdefs for ch_ and cfminbound.

Removed test for ch_
ENH/REF/API: Change defualt kind to linear.

My massive speed loss from earlier was due (apparently) to a change
from linear to cubic.  This switches back.  The speed diff is
abou 13x.

Also added in a second run through as cubic once you're close.
ENH: Some error logging.  Doesn't actually handle though.
