Shapers now can request segmented feature application by calling

callback to be called at the pause. Currently the Arabic shaper
uses pauses to enforce certain feature application. The Indic
shaper can use the same facility to pause and do reordering in the
callback.

[API] Make get_glyph() callback return a boolean
...
We need to know whether the glyph exists, so we can fallback to
composing / decomposing. Assuming that glyph==0 means "doesn't exist"
wouldn't work for applications like Pango that want to use different
"doesn't exist" glyph codes for different characters. An explicit
return value fixes that.

While the cluster fields of the glyph string are usually sorted, they

monotonic and in which direction. Not sure it's worth it though.

[API] Allow negative font x_scale/y_scale
...
I was reconsidering whether y should grow down, since all three/four
times I've used this API I was tricked and got that wrong in my use.
So I was very inclined to make y grow down instead of up. However,
considering that the font space has y up and it would be very confusing
for callbacks to work against that, I decided that what I really want
is for the user to be able to set y_scale to a negative number to imply
that user-space y grows down.
Changing x_scale/y_scale from unsigned int to int allows that, and I've
made pango to use that instead of negating glyph y_offset later. hb-ft
however still has y group up. I *guess* that's how FreeType works?
I'm not sure, FreeType docs don't make this clear...
I'm happy with the resolution :-).

[API] Make hb_face_reference_table() return empty blob instead of NULL
...
The idea here is that:
- Like pretty much all other API in harfbuzz, user does not have to
check for NULL.
- In any caller code, the case of missing table should be handled
exactly the same way that a too-short table is handled. Turning
a non-existent talbe into a table of size 0 makes the user code
safer.

[API] Remove hb_*_get_reference_count()
...
This was a bizzare piece of API that I inherited from cairo. It has
been wrong adding them to cairo in the first place. Remove them before
someone uses them!

[API] unicode: rework virtual functions for subclassing
...
Unicode data providers can now be subclassed, including support for
chain-up. The interface should now be nicely bindable, as well.
Also fix glib unicode funcs that where broken after hb_script_t
changes. Nicely caught by the test-unicode.c added in this commit.
