* enc/unicode.c: Removed artificial expansion for Turkic,

added hand-coded support for Turkic, fixed logic for swapcase.
* string.c: Made use of new case mapping code possible from upcase,
  capitalize, and swapcase (with :lithuanian as a guard).
* test/ruby/enc/test_case_mapping.rb: Adjusted for above.
  (with Kimihito Matsui)
