hb-font: Fix a potentially undefined use of memcmp() ( #413 )
...
While it’s fine to call memcmp(x, 0, 0) in practice, the C99 standard
explicitly says that this is not allowed: even if the length is zero,
the pointer arguments must be valid.

[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 :-).

Rename all private sources and headers to C++ files

So we can liberally use the simple features of C++ that parts of the
codebase is already using.

[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] Rename hb_face_get_table() to hb_face_reference_table()

That correctly reflects the reference ownership transfer happening.

[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!

Add getters for all setter APIs

One in particular is not a straight getter: hb_font_unset_funcs() is
special because of the specific needs of the lifecycle management of
the user_data object.

Fix scale issues
...
hb_font_set_scale() now sets the value to be used to represent a unit
pixel. For example, if rendering a 10px font with a 26.6 representation,
you would set scale to (10 << 6). For 10px in 16.16 you would set it to
(10 << 16). This space should be the same space that the get_glyph_metrics
and get_kerning callbacks work in.
