[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.

[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.

Disable 'cswh' by default except for Arabic shaper
...
That better matches OpenType spec. Note that we enable it for all
Arabic-shaper scripts. Ie. we enable it by default for Syriac too,
but the SyriacOT spec does not require it. I think this is a more
useful compromise than special-casing for Arabic script alone.

Let hb_shape() guess script and direction...
...
- Rename HB_SCRIPT_INVALID_CODE to HB_SCRIPT_INVALID
- Add HB_DIRECTION_INVALID
- Make hb_script_get_horizontal_direction() public
- Make hb_shape() guess script from buffer text (first non-common
non-inherit script) if buffer script is set to HB_SCRIPT_INVALID (this
is NOT the default.)
- Make hb_shape() guess direction from buffer script if buffer direction
is set to HB_DIRECTION_INVALID (this is NOT the default.)
- Make hb-view.c set INVALID script and direction on the buffer.
The above changes are meant to make hb-view fairly useful for uni-script
uni-direction text. The guessing behavior however is NOT the default of
hb_shape() and must be asked for explicitly. This is intended, because
the guess is not a suitable substitute to full-fledged bidi and script
segmentation. It's just a testing tool.
