Behdad Esfahbod dc8ed45292 [morx] Implement forward/backward processing 
We reverse too many times. Can be optimized. But I doubt many fonts
use reverse lookups, so doesn't matter.

Other than not applying user features, this completes morx table
implementation.

Simon Hausmann 6a97d0f3d3 Fix installation of cmake config when building with cmake (#1161) 
When building with the auto tools, the manually mantained
harfbuzz-config.cmake is installed. When building with cmake, we can use
cmake to generate the correct config files for us and install them.

Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert() 
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

Behdad Esfahbod 10642b3fbf Disallow null-enabled offsets to unsized structures... 
...like UnsizedArrayOf<>.

This fixes a class of crasher bugs, mostly with color and AAT tables.  We
cannot use nullable offsets to varsized data that does not declare min_size,
because it's nost safe to use our fixed-size null pool for types that have
their size external.  So, use non_null'able offsets for these.

A further enhancement would be to make use of min_size in Null<> itself.
Will try that after.

Behdad Esfahbod f8ccb545c4 [dfont] Disable null-processsing for offsets 
An offset to unsized arrayis not safe to be redirected to our fixed-sized
null pool.  Plus, we want to reject, not repair, bad-looking dfonts.

Behdad Esfahbod 3789c557ca [dfont] Solve the mystery +2 offset thing! 
Previously, ResourceForkHeader was defined as 30 bytes, having the typeCountM1 as last member.
There was a mysterious offset-by-2 in the code, derived from FontTools and JDK code this was
ported from.

In testing, I observed that typeListZ offset is actually 28.  Suggesting that the typeCountM1
does NOT actually belong to ResourceForkHeader, but belongs to the array itself.  Adjusting for
that resolves the mystery +2 offset hack, so everything is clean and good now.

This, concludes my dfont hacking.  The code looks great now, and I'm happy to leave it.
Fuzzers might disagree though, we will see!
