Revert "Zero marks by GDEF for Tibetan"
This reverts commit d5bd0590ae2fbc7b0dee86385a565aef00ffb835.
The reasoning behind that logic was flawed and made under
a misunderstanding of the original problem, and caused
regressions as reported by Jonathan Kew in thread titled
"tibetan marks" in Oct 2013. Apparently I have had fixed
the original problem with this commit:
7e08f1258da229dfaf7e1c4b5c41e5bb83906cb0
So, revert the faulty commit and everything seems to be in good
shape.

[arabic] Make ZWJ prevent ligatures instead of facilitating it
Unicode 6.2.0 Section 16.2 / Figure 16.3 says:
"For backward compatibility, between Arabic characters a ZWJ acts just
like the sequence <ZWJ, ZWNJ, ZWJ>, preventing a ligature from forming
instead of requesting the use of a ligature that would not normally be
used. As a result, there is no plain text mechanism for requesting the
use of a ligature in Arabic text."
As such, we flip internal zwj to zwnj flags for GSUB matching, which
means it will block ligation in all features, unless the font
explicitly matches U+200D glyph. This doesn't affect joining behavior.

[Arabic] Zero marks by GDEF, not Unicode category
Testing shows that this is closer to what Uniscribe does.
Reported by Khaled Hosny:
"""
commit 568000274c8edb5f41bc4f876ce21fcc8bdaeed8
...
This commit is causing a regression with Amiri, the string “هَٰذ” with
Uniscribe and HarfBuzz before this commit, gives:
[uni0630.fina=3+965|uni0670.medi=0+600|uni064E=0@-256,0+0|uni0647.init=0+926]
But now it gives:
[uni0630.fina=3+965|uni0670.medi=0+0|uni064E=0@-256,0+0|uni0647.init=0+926]
i.e. uni0670.medi is zeroed though it has a base glyph GDEF class.
"""
The test case is U+0647,U+064E,U+0670,U+0630 with Amiri.

Adjust mark advance-width zeroing logic for Myanmar
Before, we were zeroing advance width of attached marks for
non-Indic scripts, and not doing it for Indic.
We have now three different behaviors, which seem to better
reflect what Uniscribe is doing:
- For Indic, no explicit zeroing happens whatsoever, which
is the same as before,
- For Myanmar, zero advance width of glyphs marked as marks
*in GDEF*, and do that *before* applying GPOS. This seems
to be what the new Win8 Myanmar shaper does,
- For everything else, zero advance width of glyphs that are
from General_Category=Mn Unicode characters, and do so
before applying GPOS. This seems to be what Uniscribe does
for Latin at least.
With these changes, positioning of all tests matches for Myanmar,
except for the glitch in Uniscribe not applying 'mark'. See preivous
commit.

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...

Enable applying GSUB/GPOS features in multiple segments
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=644184
among others.
Shapers now can request segmented feature application by calling
add_gsub_pause() or add_gpos_pause(). They can also provide a
callback to be called at the pause. Currently the Arabic shaper
uses pauses to enforce certain feature application. The Indic
shaper can use the same facility to pause and do reordering in the
callback.

Disable 'cswh' by default except for Arabic shaper
That better matches OpenType spec. Note that we enable it for all
Arabic-shaper scripts. Ie. we enable it by default for Syriac too,
but the SyriacOT spec does not require it. I think this is a more
useful compromise than special-casing for Arabic script alone.

Bug 32274 - classic mongolian shaper
Add support for classic Mongolian script to the Arabic shaper.
Still work to be done around U+180E MONGOLIAN VOWEL SEPARATOR as it
should not be included in the final glyph stream the same way that
ZWNJ, etc should not appear in the final glyph stream.
But the joining part should be done.
There remains the question of how should the U+18A9 MONGOLIAN LETTER ALI
GALI DAGALGA be handled as it has General Category NSM but a letter
nonetheless. For now, our generic logic makes this a joining T instead
of joining D as other Mongolian letters are.

Previously boolean features turned on the entire feature mask. This is
wrong if feature is Alternate and user has provided values bigger than one.
