29f0b6bce7 CFF renaming (#1507) 
* reimplement ByteStr as byte_str_t based on hb_ubytes_t

Unuse start_embed<ByteStr>
Also renamed SubByteStr to byte_str_ref_t
More renaming to come

* substr renamed to str_ref in line with its type byte_str_ref_t

* uncamelize non-table struct names

* uncamelized non-struct types OpCode etc

* add byte_str_t copy ctor

* test

* test2

* undo tests

* fix bot failure

* undo the previous change

* fixed tabs, added inline

* Revert "fixed tabs, added inline"

This reverts commit 21163c30e9d18759414f7fe2518628241599f039.

633ce88de9 CFF Subrs subsetting 
Unreferenced subroutines are nullified (not removed) in a subset font

Separate Interpreter struct from hb-ot-cff-common-private.hh in a set of four header files, augmented for CharString (CS):
hb-cff-interp-common-private.hh
hb-cff-interp-dict-common-private.hh
hb-cff-interp-cs-common-private.hh
hb-cff-interp-cs.hh

Interpreter runtime is separated off as a new struct InterpEnv sub-classed differently for Dict and CharString (CS)

64c5412264 Added CFF support 
Added sources hb-ot-cff-table.hh, hb-subset-cff.cc & hh

00970dd242 Removed parsed hint fields from CFF2PrivateDictValues 
Instead moved & stored uniformly in values vector (renamed from opstrs)
This should be fine as we aren't likely going to use them as hints after all
Templatized DictValues whether to parse them out
For subsetter, they aren't parsed
