Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert() 
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

This reverts commit 94bfea0ce6.
This reverts commit 4e62627831.

Behdad Esfahbod 4e62627831 Enforce single-param static_assert() only 
So we don't accidentally break it again.

Behdad Esfahbod fda994e1d4 Use enum instead of "static const" in class scope 
Technically, static const needs an out-of-class definition.  Eg:

Behdad Esfahbod fee0f41c6c Don't declare extern symbols as inline 
clang -O3 was completely removing _get_gdef(), causing link
failure when needed from another compilation unit.  Surprisingly,
"extern inline" didn't fix it.

Garret Rieger 89733755a4 [subset] use add_array to populate feature_indexes. 
This is much faster then calling a bunch of individual add()'s.

Add a new API, hb_ot_layout_get_feature_name_ids (#976) 
This new API returns cvXX and ssXX related NameId, things like
featUiLabelNameId, featUiTooltipTextNameId, sampleTextNameId, ... of cvXX
and UINameId of ssXX, in a unified way.

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.

Also, uncomment code again, just "if (0)" it out, so it doesn't get stale again.

Behdad Esfahbod 7f7b1370d3 Fix Uniscribe build 
If a pointer type was passed to Null(), reinterpret_cast<> was
complaining about qualifiers being removed. Turns out I need the const on
the other side of "Type" to fix that.  Also remove unused const from
NullPool type.

Behdad Esfahbod f83e992c8b Mark CrapPool thread_local 
Not sure if I like to keep it. For now, aim for correctness.
