glibc/iconv/gconv_builtin.c
Ulrich Drepper 8d617a716d Update.
* iconv/gconv_builtin.c: Include <endian.h>.
	* iconv/gconv_builtin.h: Add UCS-BE aliases.
	Add UCS-4LE transformation.  Define UNICODEBIG and UNICODELITTLE
	according to current platform.
	* iconv/gconv_int.h: Declare __gconv_transform_ucs2reverse_internal,
	__gconv_transform_internal_ucs2reverse, and
	__gconv_transform_internal_ucs4le.
	* iconv/gconv_simple.c: Implement __gconv_transform_internal_ucs4le,
	__gconv_transform_ucs2reverse_internal and
	__gconv_transform_internal_ucs2reverse.
	* iconvdata/Makefile (modules): Add UNICODE.
	(distribute): Add unicode.c.
	* iconvdata/gconv-modules: Add definitions for UNICODE module.
	* iconvdata/unicode.c: New file.

	* iconvdata/utf-16.c: Rewrite code to emit BOM.  Correct code to
	determine byte order of input and convert accordingly.
