[subset] further changes to serializer error handling.
...
- Rename enum type and enum members.
- in_errors() now returns true for any error having been set. hb-subset now looks for offset overflow only errors to divert to repacker.
- Added INT_OVERFLOW and ARRAY_OVERFLOW enum values.

[subset] fix for collect_features and remove_redundant_lamngsys
...
previously remove_redundant_sys () is missing in harfbuzz, after
redundant langsys removal, some features are removed as well in
prune_features() in fonttools. This change is trying to get the same
result between harfbuzz and fonttools.

optimize recurse_lookups in Context/ChainContext
glyph closure, only the glyphs that the parent lookup

the lookup.

[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] Use plan->glyphset_gsub instead of plan->glyphset for GSUB/GPOS
...
This matches fontTools behaviour. glyphset_gsub does not contain gids added from closing over composite glyphs in glyf, since these cannot particpate in GSUB/GPOS processing.

Simplify get_glyph_alternates() dispatcher

Trying to make it **very simple** to add a specialized dispatcher for
one API to be routed to just a few objects (one in this case).

Use dispatch for get_glyph_alternates_t
...
First time we do this in a way that if target object doesn't have the matching
function we basically "ignore". Risky but I feel like is the right decision
for this case.
I'm going to put back the template varargs and use those, which would make
the dispatcher be just that: "dispatcher", and wouldn't need to carry the
call context. That would be a refreshing change I think.
