Automate LC_CTYPE generation for tr_TR, update to Unicode 8.0.0 (bug 18491).

This patch makes the automation of Unicode LC_CTYPE generation also
support generating the modified LC_CTYPE used for Turkish (where case
conversions of 'i' and 'I' differ from ASCII conventions), so allowing
that to be more readily kept in sync for future Unicode updates.  The
patch includes the locale update generated by the scripts.

Tested for x86_64.

	[BZ #18491]
	* unicode-gen/unicode_utils.py (to_upper_turkish): New function.
	(to_lower_turkish): Likewise.
	* unicode-gen/gen_unicode_ctype.py (output_tables): Support
	producing output with Turkish case conversions.
	(--turkish): New command-line option.
	* unicode-gen/Makefile (GENERATED): Add tr_TR.
	(tr_TR): New rule.
	* locales/tr_TR: Regenerate LC_CTYPE.
