* src/hb-cff-interp-dict-common.hh: Use ull for unsigned int64_t
The llu suffix does not work for older Visual Studio versions
(pre-2013), but ull works for all the compilers that we attempt to
support.
* test/api: Fix build on pre-C99 compilers
Ensure variables are declared at the top of the block.
* src/hb-dsalgs.hh: Add specialization for hb_is_signed<> for __int8
Pre-Visual Studio 2010 does not consider __int8 (which is typedef'ed to
int8_t) to be equivilant to signed char, so the compiler cannot find the
corresponding hb_is_signed<> specialization that is needed.
The interesting thing is unsigned __int8 is considered to be equivilant
to unsigned char, so as the other types (short, int, long) that we look
for here, so only the specialization for __int8 is added here.
This will fix builds on Visual Studio 2008 at least.
Not needed. We get it in our config.h automatically thanks to
AC_USE_SYSTEM_EXTENSIONS. Let's see whose build it breaks...
If we end up putting it back, we should add other things from
that macro and remove the macro.
* add fd index checks to subr subsetter
also added oss-fuzz test case
* undid SubrSubsetParam::is_valid
because already validated by SubrClosures.valid
The built-in operator takes signed int. So, match it, such that
the built-in is never a better or equally-good match to our operator.
Fixes "ambiguous overload" errors from gcc 4.2 and VS 2008.

I wonder if there's something better to do about these :(.

The override_features is used to override features that are normally
discretionary features, but in a specific shaper are for various
reasons desired to be bolted on or off, because they've been used
for inherent shaping. As such, it makes sense that they also
override user features. Ie. if user turned 'liga' on, we don't
want Khmer shaping to become broken... Or turn 'clig' off...
