Garret Rieger 9aa0ecef3f [subset] de-duplicate the logic that finds unicodes corresponding to requested glyphs. 
Move the logic into subset planning and then re-use the results in cmap and OS2 subsetting. Removes depedency on cmap from os2.

Behdad Esfahbod ad28f973f3 Rename offset types to be explicit about their size 
Add Offset16To<>, Offset24To<>, and Offset32To<> for most use-cases.

Garret Rieger b14475d2ae [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.

Garret Rieger 73ed59f7a6 [subset] store errors in the serializer as a flag set. 
Make check_assign/check_equal specify the type of error to set.

Qunxin Liu 8e5bc535d1 [subset] call collect_mapping only when --gids option is used. 
collect_mapping is time consuming as it iterates all codepoints in all
cmap subtables, only trigger it when necessary

Ebrahim Byagowi 07acd1a042 [subset] Rename src_base args to base to match sanitize methods 
So it will become easier to follow that serialize methods signatures should
match with their sanitize methods counterparts.

collect_unicodes() with clamp, calling add_range() 
Use add_range instead an inner loop, clamp its input number by
number of glyphs a face has.

Even the face cmap12 and 13 have 32-bit hb_codepoint_t, which is here
used to make timeout, face's maxp has 16-bit gid limitation at least for now,
using that makes sure we both fix and the timeout and don't need to change
much things here also in order to support 32-bit gids also someday.

Fixes #2204

Ebrahim Byagowi e90213868b Revert "collect_unicodes() to check gid < num_glyphs with cmap 12" 
Didn't fix the case actually, making bots to fail.

This reverts commit 15b43a4104.

Garret Rieger 52b6e0baa0 When serializing cmap14 order the offsets from smallest to largest. 
Current versions of OTS fail fonts with cmap 14's who's last offset does not point to the a block at the end of the table.

Qunxin Liu b6a8f5e63c [subset] CMAP table subsetting fix 
Not all codepoints smaller than 0xFFFF go to cmap4 table.
Only subset codepoints existing in each table.
This will also make harfbuzz consistent with fontTools' behavior
