Port Arabic fallback ligating to share code with GSUB
...
This will eventually allow us to skip marks, as well as (fallback)
attach marks to ligature components of fallback-shaped Arabic.
That would be pretty cool. I kludged GDEF props in, so mark-skipping
works, but the produced ligature id/components will be cleared later
by substitute_start() et al.
Perhaps using a synthetic table for Arabic fallback shaping was a better
idea. The current approach has way too many layering violations...

[Indic/GSUB] Ignore context when matching would_apply()
...
The MS Indic specs say "...all classifications are determined ... using
context-free substitutions." However, testing shows that MS's Malayalam
shapers (both old and new), "match" even if there is no zero-context rule.
We follow.
Fixes below-base La (eg. Pa,H,La) with AnjaliNewLipi.ttf (old spec).
Moreover, test suite Malayalam failures are down to 312 from 875! No
change in other scripts.
Current numbers:
BENGALI: 353996 out of 354285 tests passed. 289 failed (0.0815727%)

We need the font for glyph lookup during GSUB pauses in Indic shaper.
Could perhaps be avoided, but at this point, we don't mean to support
separate substitute()/position() entry points (anymore), so there is
no point in not providing the font to GSUB.

Fix the mystery bug!
...
A couple bugs joined forces to exhibit the mystery behavior of
crashes / infinite loops on OS X / wrong kerning / invalid memory
access. Pooh!
The bugs were involved:
- Wrong pointer math with ValueRecord in PairPosFormat1
- Fallout from avoiding flex arrays, code not correctly updated
to remove sizeof() usage.
We strictly never use sizeof() directly now. And the PairPos code
is cleaned up. Should fix them all. Bugs are:
Bug 605655 - Pango 1.26.2 introduces kerning bug
Bug 611229 - Pango reads from uninitialized memory
Bug 593240 - (pangoosx) Crash / infinite loop with Mac OS X
We were also doing wrong math converting Device adjustments to
hb_position_t. Fallout from FreeType days. Should shift 16, not
6. Fixed that too.
There's still another bug: we don't sanitize Device records
referenced from value records. Fixing that also.

- Return the total number of items
- Take a start_offset, such that individual items can be fetched

It's not part of the standard and MSVC doesn't like it. It makes the code
a lot less elegant than it used to be, but I think it should work now.
