All passing now.

Fixes test-set.c

Fails now.  Fixing.

If you say:

  hb-shape font.ttf text --output-file out.txt

This was previously failing:

  Unknown output format `txt'; supported formats are: TEXT / JSON

Now we simply fallback to TEXT if no explicit format was requested.

Test sequence is simple: U+0D4E,U+0D15.  The doth-reph should be
reordered to after the Ka.

Bug 54948 - Undefined symbols: "operator delete(void*)" "operator
new(unsigned long)" "___cxa_pure_virtual"

Looks at alternate location now.

To fix FeatureParam issues.  No actual fix yet, just plumbing.

We still don't look for the old incorrect place of the featureParams.
I'll wait till someone actually complains about it...

No API yet.

And add implementation for StylisticSet UINameID.  No API yet.

Bug 55494 - ScriptItemizeOpenType doesn't exists under Windows XP

Instead of checking for ApplicationServices.h, which is present in all
versions of MacOSX, check for CTFontRef, a CoreText basic type.

Patch from John Ralls.

Not sure how to handle iOS.
