f396fbb000 Fix return value of sanitize when subformat is not readable 
This is a fix on top of the previous issue fixed in
c917965b9e.

This was caught by "libFuzzer" testing.

3e905e396b Add hb_font_set_parent() 
No reason to not have it.  Makes life easier later.
We (hb-ft, hb-ot-font, etc) can use this API to inject new
parent into a font...

2a9627c564 [ft] API: Add hb_font_[sg]et_load_flags() API 
This changes the default load_flags of fonts created using
hb_ft_font_create() from NO_HINTING to DEFAULT.  Hope that doesn't
break too much client code.

Code calling hb_ft_font_set_funcs() is unaffected.

88da7bba9f Default font scale to face upem 
Makes for a better default and avoids nasty inheritance issues.

1866e17114 Make hb_font_create_sub_font() NOT make parent immutable 
We don't rely on that.  However, whenever hb_font_make_immutable()
is called, it makes its parenting chain immutable.

f2ad935e19 Handle language tags that indicate phonetic IPA transcription 
The BCP-47 registry defines a variant subtag "fonipa" that can be used
in combination with arbitrary other language tags. For example,
"rm-CH-fonipa-sursilv" indicates the Sursilvan dialect of Romansh
as used in Switzerland, transcribed used the International Phonetic
Alphabet.

5d74ff02ab Fix Since: version tags on font and face APIs 
A while back we marked every API as version:1.0.  We should fix them all
to reflect real version they were introduced.  This is a start.

Patch from Nikolay Sivov.

326b5ebf57 Poison freed objects such that double-free is detected 
Previously we were setting refcount of freed objects to the inert value, which
was harmful because it caused further destroy()s of the freed object to NOT
call free() and hence hide the bug.  Indeed, after eb0bf3ae66 test-object
was double-free'ing objects and this was never caught on Linux.  It only was
caught as crashing on Mac.

Now we poison refcount upon freeing and check that it's valid whenever reading
it.  Makes test-object fail now.

6578575cc8 [GPOS] Fix cursive connection with mix of RTL and non-RTL lookups 
See thread "Issue with cursive attachment" started by Khaled.
Turned out fixing this wasn't as bad as I had assumed.  I like the
new code better; we now have a theoretical model of cursive
connections that is easier to reason about.
