[truetype] Avoid reexecution of `fpgm' and `prep' in case of error.
Reported as
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=981
* include/freetype/fterrdef.h (FT_Err_DEF_In_Glyf_Bytecode): New
error code.
* src/truetype/ttinterp.c (Ins_FDEF, Ins_IDEF): Prohibit execution
of these two opcodes in `glyf' bytecode.
(TT_RunIns): Don't enforce reexecution of `fpgm' and `prep' bytecode
in case of error since function tables can no longer be modified
(due to the changes in `Ins_FDEF' and `Ins_IDEF'). This change can
enormously speed up handling of broken fonts.

[sfnt, truetype] Always provide default instance.
As documented in the OpenType specification, an entry for the
default instance may be omitted in the named instance table. In
particular this means that even if there is no named instance table
in the font we actually do have a named instance, namely the default
instance.
For consistency, we always want the default instance in our list of
named instances. If it is missing, we try to synthesize it.
* src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default
instance is in the table of named instances. Otherwise adjust
number of instances.
* src/truetype/ttgxvar.c: Include FT_TRUETYPE_IDS_H.

[autofit] Prevent overlapping blue zones.
Problem reported as
https://github.com/google/fonts/issues/632
The font in question (Nunito) has values 705 and 713 for the
reference and overshoot values, respectively, of the first blue
zone. Blue zone 2, however, has value 710 for both the reference
and overshoot. At 12ppem, reference and overshoot of blue zone 0
becomes 8px, while blue zone 2 becomes 9px.
A peculiarity of this font is that the tops of isolated vertical
stems like `N' have a slight overshoot also. The auto-hinter tries
to find the nearest blue zone using the *original* coordinates. For
vertical stems, this is value 713. For normal horizontal tops like
in character `E', this is value 710. Since value 713 is mapped to
8px but value 710 to 9px, `N' and similar characters are one pixel
higher than `E', which looks very bad.
This commit sanitizes blue zones to avoid such a behaviour.
* src/autofit/aflatin.c (af_latin_sort_blue): New function.
(af_latin_metrics_init_blues): Sort blue values and remove overlaps.

[autofit] Use better blue zone characters for lowercase latin.
The number of lowercase characters for computing the top flat blue
zone value was too small (in most cases only `x' and `z'). If one
of the two characters has a large serif, say, it can happen that
FreeType must select between two different values, having a 50%
chance to use the wrong one. As a result, rendering at larger PPEM
values could yield uneven lowercase glyph heights.
Problem reported by Christoph Koeberlin <christoph@koe.berlin>.
* src/autofit/afblue.dat (AF_BLUE_STRING_LATIN_SMALL): Replaced
with...
(AF_BLUE_STRING_LATIN_SMALL_TOP, AF_BLUE_STRING_LATIN_SMALL_BOTTOM):
... New, extended sets.
(AF_BLUE_STRINGSET_LATN): Updated.
* src/autofit/afblue.c, scr/autofit/afblue.h: Regenerated.

[cff] Provide metrics variation service interface (#50196).
Only now I've got an OTF with an HVAR table for testing...
The code in `ftmm.c' uses `FT_FACE_LOOKUP_SERVICE' to get the
metrics variations interface. However, this didn't work with
`FT_FACE_FIND_GLOBAL_SERVICE' used in `sfnt_init_face'.
* src/cff/cffdrivr.c: Include FT_SERVICE_METRICS_VARIATIONS_H.
(cff_hadvance_adjust, cff_metrics_adjust): Wrapper functions for
metric service functions from the `truetype' module.
(cff_service_metrics_variations): New service.
(cff_services): Updated.
* src/cff/cffpic.h (CFF_SERVICE_METRICS_VAR_GET): New macro.
[FT_CONFIG_OPTION_PIC]: Synchronize code.
* src/sfnt/sfobjs.c (sfnt_init_face): Replace call to
FT_FACE_FIND_GLOBAL_SERVICE with `ft_module_get_service' to always
load the service from the `truetype' module.
