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.

New API:

- hb_font_get_variation_glyph()
Deprecated API:
- hb_font_get_glyph_func_t
- hb_font_funcs_set_glyph_func()
Clients that implement their own font-funcs are encouraged to replace
their get_glyph() implementation with a get_nominal_glyph() and
get_variation_glyph() pair. The variation version can assume that
variation_selector argument is not zero.

Make nil glyph_h_origin() function return true

Fixes https://github.com/behdad/harfbuzz/issues/187
Funcs implementations that have a non-zero horizontal origin must
implement the glyph_h_origin() callback, nothing new here.
Other implementations (all I know of!) can simply not set
glyph_h_origin() now. I did that for hb-ot and hb-ft in
44f8275080
, though that broke the
fallback shaper because the default was returning false...
