Thanks to Brian Wang for the report.
This happened because we were querying for the index of the wrong fi,
this became especially visible after we started caching fi.

Soon I will also do it for all cases, but it's not possible at the
moment because we depend on harfbuzz for querying unicode properties.

Kerning: We are walking the string visually so we don't need to do
anything special for kerning when in rtl, freetype works with "left" and
"right" which we automatically get.
Rendering bug: Cedric found that in some cases there were missing
characters. This was caused because I forgot to convert the kerning from
16.6 fixed point to int.

We only really use adavnce for calculating the pen position, so it makes more
sense to just cache the pen_position instead and calculate advance from
that if ever needed.
This means size/advance calculations are now O(1) because we don't need to
walk the strings anymore.

It's only really used (and will ever be used) in a very specific place,
no need to put it in a place that's visible to all the lib.

Now when setting :style=Oblique/Italic/Cursiva/Bold and etc and there's
no matching font found in the system, adjustments will be done on
runtime to support that feature.
Patch by Myoungwoon Roy Kim (roy_kim).

I'm still not sure if it's just a workaround that just fixes a symptom
of a bigger issue, or actually needed, but this is good until I figure
this out completely.

strings in most of the font engine (everywhere except draw).
Haven't removed the paramteres yet, but did mark them as UNUSED.
Removing them will be part of a future change.
Removed run-time OT toggling support, OT is now fast, no need for that.
Renamed all of the intl_props->text_props (because it really changed purpose now)
Fixed spliting/merging of text_props to be fast and good, not hacky and
complex like before.
Note to reviewers: Most of the changes are indentation related, sorry
for the mess, but I had to do it all in one commit, splitting was not
trivial (at least not in retrospect). The important parts are
evas_font_default_walk.x and text_utils.c. query and draw were just
adjusted a bit and the rest were only adjusted to conform to renaming or
were renaming on their own.

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.
