The table can now compile independently too.  If we cannot make it work
on MSVC, we can always generate the data and distribute it.

The code now compiles cleanly with:

gcc -c -xc -std=c99 -Werror -pedantic hb-ot-shape-complex-arabic-win1256.hh
g++ -c -xc -std=c++1x -Werror -pedantic hb-ot-shape-complex-arabic-win1256.hh

Bug 1045139 - The Arabic text with "MS Sans Serif" font is rendered bad
https://bugzilla.mozilla.org/show_bug.cgi?id=1045139

This is only enabled on Windows platforms, and requires support from
Uniscribe to work.  But for clients that do hook up to Uniscribe, this
fixes shaping of Windows-1256-encoded bitmap fonts like "MS Sans Serif".

The code and table together have just less than a 1kb footprint when
enabled.

UNTESTED.  I might even have broken regular Arabic fallback shaping.

Seems to be what Uniscribe does.

At this point I think it's work checking our default...

Fixes Bug 76767 - Zeroing of advance of 2nd component of multiple
substitution with SBL Hebrew
https://bugs.freedesktop.org/show_bug.cgi?id=76767

Micro-test added.

Looks like Unsicribe responds to the 'mymr' tag by zeroing marks
GDEF_LATE instead of generic-shaper UNICODE_LATE.  Implement that.

Bug 81775 - Incorrect Rendering with harfbuzz-ng myanmar unicode

Micro-test added based on Padauk.

Patch from Maks Naumov.

If user doesn't check hb_feature_from_string() return value, we
don't want them to end up see the partially-parsed feature.

With this, I believe we accept CSS feature strings completely.

We now allow things like "dlig on" / "dlig=on".

It's defined in hb-private.h already.

Towards accepting CSS font-feature-settings strings.

Some systems insist on -Wmissing-field-initializers.  We have too many,
by design.  Fix a few easy ones.

See comment.

Micro-tests added.

Ouch!

Follows the order of the Arabic/Syriac specs.  Also don't stop
between rlig and calt in non-Arabic scripts.

Micro-tests for Arabic and Mongolian added for the latter.
