[set] Add add_sorted_array()
...
Not optimized to use sortedness yet. Also start putting in place infra
to faster reject bad data.
A version of Chandas.ttf found on some Chrome bots has 660kb of GPOS,
mostly junk. That is causing 48 million of set->add() calls in
collect_glyphs(), which is insane.
In the upcoming commits, I'll be speeding that up by optimizing
add_sorted_array(), while also reducing work by rejecting out-of-sort
arrays quickly and propagate the rejection.

Fix build of HarfBuzz tools and HarfBuzz-GObject on Visual Studio ( #555 )
...
* hb-buffer.h: Mark hb_buffer_diff() for export
This will fix the tools builds on Visual Studio, as the symbol is used
by the tools.
* build: Adapt NMake Makefiles for GLib 2.53.4 or later
glib-mkenums was ported from a PERL script to a Python script, so we
need to update how we generate the enum sources for HarfBuzz-GObject in
the NMake builds. Let this be known in the build documentation for MSVC
builds.
One of the problems with the underlying cmd.exe that the NMake Makefiles
run on is that shebang lines are not recognized, so we need to to test
run the script with Python and see whether it succeeded by outputing a
source file that is larger than 0 in file size (since running the PERL
version of the script will clearly fail and cause an empty file to be
created).
If it succeeds, we then run a small Python utility script that makes the
necessary string replacements, and we are done. If that fails, then we
run the glib-mkenums script with PERL, and do the replacements with the
PERL one-liners as we did before.
We need to make replace.py use latin-1 encoding when using Python 3.x to
cope with the copyright sign that is in the generated enum sources.

If an application provides a malloc replacement through

causes system malloc() to be called instead. This pairs

With the fuzz-testcase in mozilla bug 1295299, we end up with a recursed lookup that removes 3 items, when `match_positions[idx]` is 0, which results in (unsigned) `end` wrapping to a huge value.
Making `end` a signed int is probably the simplest route to a fix.
