Subject: [PATCH] Make all emoji dicts for fully qualified
Currently only emoji-en.dict enables fully qualified since it imports
emoji-test.txt and it causes to hardly compare emojis between
emoji-en.dict and emoji-$lang.dict when m_show_emoji_variant
is enabled. E.g. U+1F3CC-FE0F-200D-2642-FE0F
Now emoji-$lang.dict also import emoji-test.txt and enables
fully qualified.

Subject: [PATCH] Integrate custom rendering to use HarfBuzz glyph info
IBusFontSet offers FcFontSet, glyph info with HarfBuzz and rendering
on Cairo context.
Current Pango changes fonts by emoji variants and draws the separated
glyphs [1] but actually the emoji characters with variants can be drawn
as one glyph so this class manages Fontconfig fontsets to select a font,
HarfBuzz to get glyphs for emoji variants, Cairo to draw glyphs.
Need configure --enable-harfbuzz-for-emoji option to enable this feature.
