Let shapers decide when to apply ccmp and locl
...
Instead of always applying those two features before the complex shaper,
let the complex shaper decide whether they should be applied first.
Also add stub for Indic's final_reordering().

[API] Add compose() and decompose() unicode funcs, rename other ones
...
Add compose() and decompose() unicode funcs. These implement
pair-wise canonical composition/decomposition.
The glib/icu implementations are lacking for now. We are adding
API for this to glib, but I cannot find any useful API in ICU.
May end of implementing these in-house.
Changed all unicode_funcs callback names to remove the "_get" part.
Eg, hb_unicode_get_script_func_t is now hb_unicode_script_func_t,
and hb_unicode_get_script() is hb_unicode_script() now.

[Vertical] fix vertical gpos
...
Wow, it took me a few days to find the right fix!
We now set the advance for attached marks to zero, but we
do this in the _finish() state of gpos, so it shouldn't
regress with fonts like DejaVuSansMono that explicitly
decrease the mark advance width to set it to zero.

[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.

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.
