c0a6814b49 Touch up new API 
New API:
+hb_ot_layout_feature_get_name_ids()

477bc9aafe Add hb-ot-name.h 
Actual name-fetching API to come later.

New API:
hb_name_id_t
HB_NAME_ID_INVALID

dc49bd8d81 Add two APIs for getting stylistic set labels 
* hb_ot_layout_feature_get_characters
* hb_ot_layout_feature_get_name_ids

However HarfBuzz currently doesn't expose an API for retrieving the actual
information associated with NameId from the `name` table and that should be
done separately.

e9f9c0d81c [sanitize] Reorder condition to silence bogus gcc warning 
Was givin a dozen of:

../../src/hb-machinery.hh: In member function ‘bool AAT::ankr::sanitize(hb_sanitize_context_t*) const’:
../../src/hb-machinery.hh:307:23: warning: missed loop optimization, the loop counter may overflow [-Wunsafe-loop-optimizations]
     bool ok = --this->max_ops > 0 &&
               ~~~~~~~~~~~~~~~~~~~~~~
        this->start <= p &&
        ~~~~~~~~~~~~~~~~~~~
        p <= this->end &&
        ~~~~~~~~~~~~~~~^~
        (unsigned int) (this->end - p) >= len;
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I believe those are bogus, but this silences them and does not introduce
logic issues I believe.

68c86af187 Always compile deprecated symbols 
We haven't been keeping this updated.  So, while we don't expose the
symbols in the headers if HB_DISABLE_DEPRECATED is defined, we still
always build them.

bf8469be9a Attach CursivePositioning backwards, not forward 
This is how Uniscribe does it.  So, adjust.  This is only relevant
to fonts that apply cursive positioning from a contextual lookup.

2c824d3644 [aat] Fix two wrongs that made a right before! 
Unfortunately our static asserts (DEFINE_SIZE_STATIC) don't actually
fail when used in templates, thanks to SFINAE.  Le sighs.
