Use bkgrndset() as ATTRSET() backend if available.

This function allows more usable color pairs, because it passes the
pair parameter separately.  The COLOR_PAIR() macro only returns 8-bits
for a pair, limiting the total pairs used to 256 despite many systems
having much larger COLOR_PAIRS values.

In order to do this, separate out the pair and attrs values, instead
of combining attr + COLOR_PAIR(pair) into a single value and storing
that inside Mutt.  For the older calls, bkgdset() and attrset(), we
call COLOR_PAIR() at the last minute.

Add COLOR_ATTR to header cache sum calculation, since it is used in
the HEADER now.
