1f5a54c768 [gvar] fix infinite loop introduced by 11f3fca 
The attempt on removing end_points had made the code unreadable
and has intrdouced infinite, fixed by making the code clear what
it tries to achieve.

493e40ff78 [subset] add one empty byte to glyf table 
if it's going to end up empty after subsetting
This will make OTS happy and match what fontTools is doing now.

ff984ed3cd Use multiplication to avoid undefined behaviour per clang 
Newer versions of MSVC with /we4146 don't like putting negative sign behind a
unsigned number as https://github.com/harfbuzz/harfbuzz/pull/2069
That however have made https://crbug.com/1050424 this complain:
  src/hb-ot-color-sbix-table.hh:304:28: runtime error: negation of -2147483648 cannot be represented in type 'int';
                                        cast to an unsigned type to negate this value to itself
which apparently can be fixed using this change.

Let's see if this won't make another ubsan complain!

2742c81624 Fix page_map corruption in hb_set_t during process(). 
If a process operation results in less pages then the current set has, it will likely corrupt the page_map since it overwrites page_map entries ahead of where it's processing. This fixes that problem by removing page_map entries that will be dropped. Then dropping orphaned pages and re-indexing retained pages.

[subset] Avoid incorrectly dropping cmap for NotoColorEmoji.ttf 
NotoColorEmoji.ttf uses two cmap subtables

 Format 14 | Platform ID 0 | Platform Encoding ID  5
 Format 12 | Platform ID 3 | Platform Encoding ID 10

This combination results in the cmap table being dropped during subsetting despite being valid/required.

490ef1cc23 [subset] Fix namerecord ordering 
This will fix inconsistency with fontTools.
Also according to the spec, namerecords must be sorted
first by platform ID, then by platform-specific ID,
then by language ID, and then by name ID.

b6a8f5e63c [subset] CMAP table subsetting fix 
Not all codepoints smaller than 0xFFFF go to cmap4 table.
Only subset codepoints existing in each table.
