* common.mk: Added two more precondition files for enc/unicode/casefold.h
* enc/unicode.c: Added shortening macros for enc/unicode/casefold.h
* enc/unicode/case-folding.rb: Fixed file encoding for CaseFolding.txt
to ASCII-8BIT (should fix some ci errors). Clarified usage. Created
class MapItem. Partially implemented class CaseMapping.
