9cc1ed4fa6 Do not allow recursiving to same position and same lookup 
This is just to make it harder to be extremely slow.  There definitely
are ways still, just harder.  Oh well... how do we tame this problem
without solving halting problem?!

85062e3b46 Add tests for previous two commits 
To fully test what these are supposed to test, they should be run
against libharfbuzz-fuzzing.la instead of libharfbuzz.la, but for
now just record the files.

6e6f82b6f3 Implement SYRIAC ABBREVIATION MARK with 'stch' feature 
The feature is enabled for any character in the Arabic shaper.
We should experiment with using it for Arabic subtending marks.
Though, that has a directionality problem as well, since those
are used with digits...

da29b43794 Separate nil font-funcs from parent-peeking font-funcs 
API change: all fonts created with hb_font_create() now inherit from
(ie have parent) hb_font_get_empty().

for it.  Currently fails.

49ef630936 Adjust the width of various spaces if font does not cover them 
See discussion here:
81ef4f407d

There's no way to disable this fallback, but I don't think it would
be needed.  Let's hope for the best!

7793aad946 Normalize various spaces to space if font doesn't support 
This resurrects the space fallback feature, after I disabled
the compatibility decomposition.  Now I can release HarfBuzz
again without breaking Pango!

It also remembers which space character it was, such that later
on we can approximate the width of this particular space
character.  That part is not implemented yet.

We normalize all GC=Zs chars except for U+1680 OGHA SPACE MARK,
which is better left alone.

df698f3299 [ot-font] Fix hmtx table length checking, *again* 
Exactly the same problem that I fixed in
63ef0b41dc

I rewrote the table checking yesterday in
67f8821fb2
and introduced the exact same issue again. :(
Good thing we have ongoing fuzzing going now.  Was discovered
immediately by libFuzzer.  Thanks kcc!

parent into a font...

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.

b3a2f6afba [test] Add test for cluster merging 
Based on test from https://code.google.com/p/chromium/issues/detail?id=497578

Currently fails.  Basically, if there's a default_ignorable at the
start of text, and font has no space glyph, we remove the default_ignorable,
and that makes the first char in text to correspond to no cluster.

Fix coming.

eb0bf3ae66 Relax inert checks 
Previously, when creating an object from inert inputs (eg:
"hb_font_create(hb_face_get_empty())") we returned the inert
empty object.  This is not helpful as there are legitimate
usecases to do that.

We now never return the inert object unless allocation failed.

Tests are revised to reflect.
