Qunxin Liu 540f19b6fe [subset] fix bug in (Chain)ContextFormat2

Qunxin Liu 364b6b3989 [subset] Don't assume FeatureList is sorted
Though the spec said FeatureRecords are sorted alphabetically by feature
tag, there're font files with unsorted FeatureList. And harfbuzz is not
able to subset these files correctly because we use binary search in
finding featureRecords when collecting lookups. Also
find_duplicate_features needs to be updated to handle this.

Garret Rieger c2cc566c9d [subset] Fix subset_offset_array adding unused space to serializer.
ArrayOf.serialize_append allocates space for the new item, but ArrayOf.pop() does not recover the allocated space. So in the case where the revert path was entered the extra space added by serialize_append gets left in the serialization buffer. This moves the snapshot to before ArrayOf.serialize_append is called so that revert cleans up the buffer extend.

Qunxin Liu b4fc593c3c [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

Garret Rieger 8f47dd5779 [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.

Dominik Röttsches a5f6f869e8 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.

Garret Rieger e583505334 [subset] Use plan->glyphset_gsub instead of plan->glyphset for GSUB/GPOS

Garret Rieger 940e1c6f98 [subset] ChainContextFormat3 - don't subset glyph sequences.
The backtrack, input, and lookahead sequence must be matched in their entirety so these sequences should not be subset. If any of the coverage tables in a sequence subsets to empty then the whole subtable should be dropped since it's not possible for this lookup to be activated.

Behdad Esfahbod ffe8d3f39d 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.

So it will become easier to follow that serialize methods signatures should
match with their sanitize methods counterparts.

Behdad Esfahbod c14efb8e68 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.

Behdad Esfahbod 95df00aec1 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++
