Behdad Esfahbod 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!

Behdad Esfahbod 67f8821fb2 [ot] Make bad-hmtx handling match FreeType
Also route fuzzing-related tests through hb-ot-font, to reduce dependency
on FreeType behavior for badly-broken fonts.  Fixes failing test with
FreeType master.

Behdad Esfahbod 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...

Behdad Esfahbod 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.

Sascha Brawer 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.

which contains all required flags.

Behdad Esfahbod 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.

Behdad Esfahbod 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.

Behdad Esfahbod 9868749abe [test] Use /usr/bin/env python instead of /usr/bin/python

Ebrahim Byagowi 363ceec3fb Make hb_test_tools.py compatible with python 3
On ArchLinux, /usr/bin/python is linked to python 3 so
HarfBuzz `make check` is broken there.

This makes hb_test_tools.py compatible with python 3 while
no breaking it on python 2.

Behdad Esfahbod 7d5e7613ce Fail blob creation if length overflows or is too large
Fail if blob start plus length overflows; or if blob length
is greater than 2GB.  It takes a while for fonts to get to that
size.  In the mean time, it protects against bugs like this:

  http://www.icu-project.org/trac/ticket/11450

Also avoids some weird issues with 32bit vs 64bit systems
as we accept length as unsigned int.  As such, a length of
-1 will cause overflow on 32bit machines, but happily
accepted on a 64bit machine.  Avoid that.

Behdad Esfahbod e6f80fa104 [indic] Allow ZWJ/ZWNJ before SM
In Oriya, a ZWJ/ZWNJ might be added before candrabindu to encourage
or stop ligation of the candrabindu.  This is clearly specified in
the Unicode section on Oriya.  Allow it there.  Note that Uniscribe
doesn't allow this.

Micro tests added using Noto Sans Oriya draft.

Behdad Esfahbod b5fbc3b8f5 API: Do not clear buffer-flags in hb_buffer_clear_contents()
After 763e5466c0, one doesn't
need to set flags for different pieces of text.  The flags now
are something the client sets up once, depending on how it
actually uses the buffer.  As such, don't clear it in
clear_contents().

Tests updated.
