ftxbbox.c, ftcalc.c, ftdebug.c, ftdriver.h:
doc fixes.
ftdebug.c:
formatting.

reflect the new modules/drivers list management performed through the
file `freetype2/config/modules.mk'

list management. We get rid, at last, of the infamous pre-processor
tricks used to build the list at compile time.
`src/base/ftinit.c' is also modified to reflect the changes..
