prune_features() in fonttools. This change is trying to get the same

[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] don't set lookup visited in closure_lookups_context_t::recurse.
...
- Lookup::closure_lookups also checks if the lookups visited and sets the lookup to visited. If we set visited in 'recurse' then Lookup::closure_lookups will fail to recurse into the children of the lookup.
- Also when copying ChainRule's skip LookupRecord's that point to lookups which aren't retained. This matches FontTool's behaviour.

Drop layout table if layout lookup accelerator allocation failed
...
If the table is kept, when the table is present but only the accelerator
allocation failed, then we run into nullptr dereferences downstream in
hb_ot_map_t::apply when trying to access proxy.accels[i].
To fix this, instead of only setting lookup_count of accelerator_t
itself, drop the whole table to avoid hb-ot-map construction assuming
that the lookups will work correctly despite accelerator allocation
having failed.

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.

Fix previous commit
...
Priority should be given to specific over dispatch. Broke sanitize before.
This fixes it, by moving prioritization to the context implementation, since
the correct priority cannot be done in the dispatch implementation. Done
for subset and sanitize only, which need it.

Hide a few static methods
...
Looks like static methods that do not get inlined end up exported.
We have a lot more. Need to protect all at some point. Wish there
was an easier way, like the visibility flag we pass that automatically
hides all inline methods.
Was exposed by check-symbols.sh when compiling on OS X 10.14 with:
$ make CPPFLAGS=-Oz CXXFLAGS=-flto=thin LDFLAGS=-lc++
