GB18030: Help transitioning away from PUA code points. * lib/gb18030ext.h (gb18030_2005_ext_wctomb): Remove function. (gb18030ext_wctomb): Renamed from gb18030_2022_ext_wctomb. * lib/gb18030uni.h (gb18030_2005_uni_wctomb): Map 6 Ext-B code points to 4-bytes sequences. (gb18030_2022_uni_wctomb): Small refactoring. * lib/gb18030_2005.h (gb18030_2005_pua2charset): Map 6 PUA code points to 4-bytes sequences instead of 2-bytes sequences. (gb18030_2005_wctomb): Update accordingly. Invoke gb18030ext_wctomb instead of gb18030_2005_ext_wctomb. * lib/gb18030_2022.h (gb18030_2022_wctomb): Invoke gb18030ext_wctomb instead of gb18030_2022_ext_wctomb. * tests/GB18030-2005.IRREVERSIBLE.TXT: Update the inverse mappings of 6 Ext-B code points and 6 PUA code points. * NEWS: Mention it.
