- use '-w' instead of '\<...\>' for check-header-guards
grep manpage says these are the same
- put '-q' first in the grep options
- move VAR into hb-private.hh
- hb-font-private.hh - use [VAR] instead of [] for variable array
Back in the old days, we used to apply 'calt' and 'cswh' in Arabic shaper,
with a pause in between. Then we disabled the 'cswh' because Microsoft
disabled it, but forgot to remove the unnecessary pause. Do that now.
This has the benefit that it fixes shaping with monbaiti from Windows 10.
In that version of that font, the lookups from 'calt' are duplicated in
'rclt', and Mongolian was changed to go through Universal Shaping Engine.
We still use the Arabic shaper for Mongolian. With a pause after 'calt',
we were applying the duplicate lookups from 'calt' and 'rclt' twice. It
happened to be the case that these lookups were NOT idempotent. So we
were getting wrong shaping. See thread "Windows 10 monbaiti.ttf upgrade
(5.01 -> 5.51) caused loss of diacritical marks when shaped with harfbuz"
on the mailing list. This fixes that.
This aims to make Syriac Abbr Mark sizing more accurate when repeating segments are used, by adding an extra repeat and tightening up the spacing slightly rather than leaving a shortfall corresponding to a partial repeat-width.
This was brorken earlier, though, it's really hard to notice it.
Unlike the glyph_h_origin(), an unset glyph_v_origin() does NOT
mean that the vertical origin is at 0,0.

Funcs implementations that have a non-zero horizontal origin must
implement the glyph_h_origin() callback, nothing new here.
Other implementations (all I know of!) can simply not set
glyph_h_origin() now. I did that for hb-ot and hb-ft in
44f8275080, though that broke the
fallback shaper because the default was returning false...
This prepares the headers for exporting symbols using visibility
attributes or __declspec(dllexport), so that we do not need to maintain
symbols listing files, as this is what was and is done in GLib and GTK+.
This is just to make it harder to be extremely slow. There definitely
are ways still, just harder. Oh well... how do we tame this problem
without solving halting problem?!

This essentially disables coverity-scan right now, until we find
a pattern to continuously submit branches there.
For background reasoning, see:

To fully test what these are supposed to test, they should be run
against libharfbuzz-fuzzing.la instead of libharfbuzz.la, but for
now just record the files.
