Fix unintentional locale dependency ( #3358 )
...
Avoid unintentional locale dependency
hb_variation_to_string uses sprintf with %g, which will produce
a locale-dependent decimal point, which is not desired here.
The output is supposed to be compatible with CSS syntax, and
that always uses '.' for the decimal point.
Fix this by changing the per-thread locale to "C" around sprintf call.

[repacker] Improve vertex priority packing.
...
Previous priority implementation would move a node further back within it's layer, but at max priority was unable to move any further up than that. This updates the implementation to have 3 priority levels:
1. Distance is reduced by half of table size.
2. Distance is reduced by full table size (move to beginning of the layer).
3. Distance is set to 0. Vertex will be packed as soon as possible.
Also makes the iterative resolutions aware of max priority, so it won't keep trying to raise priority beyond the maximum.

Ligature subtables use virtual links to enforce an ordering constraint between the subtables and the coverage table. Unfortunately this has the sideeffect of prevent the subtables from being shared by another Ligature with a different coverage table since object equality compares all links real and virtual. This change makes virtual links stored separately from real links and updates the equality check to only check real links. If an object is de-duped any virtual links it has are merged into the object that replaces it.

The current CMAP4 implementation uses whatever the current codepoint ranges are and then encodes them as indivudal glyph ids or as a delta if possible. However, it's often possible to save bytes by splitting up existing ranges and encoding parts of them using deltas where the cost of splitting the range is less than encoding each glyph individual.

[subset] Don't assume FeatureList is sorted
...
Though the spec said FeatureRecords are sorted alphabetically by feature
tag, there're font files with unsorted FeatureList. And harfbuzz is not
able to subset these files correctly because we use binary search in
finding featureRecords when collecting lookups. Also
find_duplicate_features needs to be updated to handle this.

[subset] During LigatureSubstFormat1 subsetting always place Coverage last.
...
In Windows 7 on Chrome if the coverage table comes before any of the LigatureSet or Ligature subtables the font won't load. This changes the packing order to always place the Coverage table last. Virtual links are used to ensure the repacker maintains the desired ordering.

Fix Wbitwise-instead-of-logical warnings
...
`a || b` only evaluates b if a is false. `a | b` always evaluates
both a and b. If a and b are of type bool, || is usually what you
want, so clang now warns on `|` where both arguments are of type bool.
This warning fires twice in harfbuzz. In both cases, `|` is used
intentionally, with a comment explaining this.
Slightly reorder the code a bit to make the compiler happy, and to
make it obvious even without a comment that both calls should be evaluated.
No intended behavior change.

[meson] Add ragel subproject
...
If ragel 6.10 is not found, build it from source.
Seems to work, except that ragel uses exceptions and we configure
HarfBuzz build to not use exceptions, and I can’t find away to enable
exceptions only for the ragel subproject. I had to remove cpp_eh=none
from default options and try to disable exceptions in MSVC manually
(other compilers are already handled).
