cdcdfe61b9 Err, instead of warn, if mutex / atomic / unicode funcs are missing 
Hopefully this results in fewer badly built HarfBuzz integrations.

3f174cd020 Minor refactoring to the atomics implementation 
s/atomic_int/atomic_int_impl/ and s/atomic_ptr/atomic_ptr_impl/
to bring it in par with hb_mutex_impl_t, then re-introduce
hb_atomic_int_t as a wrapper around hb_atomic_int_impl_t.

In hb_reference_count_t, make it clear the non-atomic get and set
are intentional due to nature of the cases they are used in
(comparison to -1 and the debug output/tracing).

8ac345e5c0 Fix reverse_range() to only reverse alt array if positions are used 
In hb-coretext, when we were using scratch buffer for book-keeping,
a reverse_range() caused by the notdef-insertion loop could mess up
our log_clusters.  Ouch!

5175300fba [layout] Fix comparison of GlyphID and hb_codepoint_t 
Before, the IntType::cmp functions providing this and was truncating
the hb_codepoint_t to 16bits before comparison.  I have no idea how
this was never discovered, and I'm too lazy to try to reproduce this
with Pango (which uses non-16bit codepoint numbers for missing glyphs).

640b66c634 [layout] If lookup has only one subtable, move the forward loop down to subtable

de2118ed7a Make sanitize() a const method 
This makes a lot of code safer.  We only try modifying the object in one
place, after making sure it's safe to do so.  So, do a const_cast<> in
that one place...

baa14e1814 [lookup] Don't initialize skippy if coverage match fails 
Currently:

  - Initializing skippy is very expensive,

  - Our lookup accelerator (using set-digests) can be very ineffecite,

As such, we end up many times initializing skippy but then failing
coverage check.  Reordering fixes that.

When, later, we fix our accelerator to have truly small false-positive
rate (for example by using the frozen-sets), then we might want to
reorder these checks such that we wouldn't calculate coverage number
if skippy is going to fail.

This shows a 5% speedup with Roboto already.
