Avoid undefined-behavior
...
If a struct had (because it's a union) sizeof that is larger than the null_size,
we were providing only null_size bytes for its Null object. We know we'd never
access beyond that, but is undefined-behavior nonetheless according to the
standard.
The alternative fix would have required use of flexible-arrays, which are not
standard and have their own issues in various compiler. We've discussed that
extensively in the follow Mozilla issue (currently locked; I've asked that it
be opened):

Currently config-override.h is included at the end of this file.

[subset] optimize glyph closure method: step1
...
Previous GSUB glyph closure is done by recursively visiting
all reachable lookup tables that apply to any glyphs in the
current/input glyph set, but actually only the glyphs that
the parent lookup can apply the recursion to can participate
in recursing the lookup. This is step 1 for glyph closure
optimization:
1. Add stack of currently active glyph set pointers into hb_closure_context_t
2. Update closure() method in simple GSUB tables to use
this stack in order not to change current glyph set at different stages
of recursion
3. Add function may_have_non_1to1() to GSUB tables

- subset class def 1 against the coverage table.
- Don't re-use class 0 in class def 2.
- Ignore class 0 glyphs for the purposes of determing format 1 vs format 2 encoding for ClassDef.
Add an additional test case which demonstrates these issues.

[buffer] Fix order of HB_INTERNAL HB_DISCARD
...
Sucks that has to be specified in this order. But that is what it is for now.
Was only exhibiting problem on C++>=17 since that's when the [[nodiscard]]
was introduced.

To my surprise, saves ~20kb in my build (non-size-optimized) build.
The output_glyph() method is never used in the fast paths, so doesn't
matter if is not fully optimized for the special case it is.

[buffer] Return success status from buffer ops that can fail
...
Previous error-handling philosophy was that user doesn't need to
immediately know whether operation failed. But as can be seen after
we added malloc-failing fuzzing, there's just so many places in the
code that a failure of these operations needs to be mitigated before
further operations. So I'm moving towards returning success here,
and possibly making it nodiscard.

[hangul] Improve error handling
...
I did a review; changed some "return"s to "break"s, which should be identical.
Removed one check just before "continue" because not necessary.
The added error check is the actual fix.
Should fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=31755

[subset] Make ClassDef format2 .intersects() return false if range value 0
...
We treat Class0 as "doesn't intersect". That's the only meaningful
interpretation. If one allos Class0 to mean "intersects", then the
intersects() result should be true iff glyphset is non-empty.

After this change, HarfBuzz output matches that of Uniscribe and
