Avoid accessing layout tables at face destruction
"Fixes" https://bugs.freedesktop.org/show_bug.cgi?id=86300
Based on discussion someone else who had a similar issue, most probably
the user is releasing FT_Face before destructing hb_face_t / hb_font_t.
While that's a client bug, and while we can (and should) use FreeType
refcounting to help avoid that, it happens that we were accessing
the table when we didn't really have to. Avoid that.

[arabic/win1256] Remove GCC'ism
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

[arabic] Implement Windows-1256 private shaping
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.

Initialize set digests
We were not initializing the digests properly and as a result they were
being initialized to zero, making digest1 to never do any useful work.
Speeds up Amiri shaping significantly.

[Indic] Futher adjust ZWJ handling in Indic-like shapers
After the Ngapi hackfest work, we were assuming that fonts
won't use presentation features to choose specific forms
(eg. conjuncts). As such, we were using auto-joiner behavior
for such features. It proved to be troublesome as many fonts
used presentation forms ('pres') for example to form conjuncts,
which need to be disabled when a ZWJ is inserted.
Two examples:
U+0D2F,U+200D,U+0D4D,U+0D2F with kartika.ttf
U+0995,U+09CD,U+200D,U+09B7 with vrinda.ttf
What we do now is to never do magic to ZWJ during GSUB's main input
match for Indic-style shapers. Note that backtrack/lookahead are still
matched liberally, as is GPOS. This seems to be an acceptable
compromise.
As to the bug that initially started this work, that one needs to
be fixed differently:

[Indic-like] Disable automatic joiner handling for basic shaping features
Not for Arabic, but for Indic-like scripts. ZWJ/ZWNJ have special
meanings in those scripts, so let font lookups take full control.
This undoes the regression caused by automatic-joiners handling
introduced two commits ago.
We only disable automatic joiner handling for the "basic shaping
features" of Indic, Myanmar, and SEAsian shapers. The "presentation
forms" and other features are still applied with automatic-joiner
handling.
This change also changes the test suite failure statistics, such that
a few scripts show more "failures". The most affected is Kannada.
However, upon inspection, we believe that in most, if not all, of the
new failures, we are producing results superior to Uniscribe. Hard to
count those!
Here's an example of what is fixed by the recent joiner-handling
changes:
