1. Split to logical layout units.
2. Order the logical layout units in a visual way.
This lets us cache the results of the first part (unless the text changes), which makes everything a lot faster in the OT case, and quite faster in the regular case.
There are still some issues unresolved in this commit that will be resolved in future commits:
1. No support for async rendering - yes, I forgot I'm supposed to support that.
2. native_size should probably be calculated in another way because the current one is slow and if we already have the logical items it should be a piece of cake...

1. Started feeding Evas_Text_Props to the font engine instead of Evas_BiDi_Props because no we have more general text properties as well - i.e, OpenType stuff.
2. Full Harfbuzz integration which gets compiled in by default (if harfbuzz is present) but only works if the environment variable EVAS_USE_OT is set to 1 (because OT is way slower than regular text rendering).
3. Cleaned the font querying/drawing functions.
4. Added font_shaped function to all of the engines, which by default calls teh harfbuzz stuff (default on linux that is).
5. Moved some source files around a bit to make more sense.
