[layout] Fix comparison of GlyphID and hb_codepoint_t
...
Before, the IntType::cmp functions providing this and was truncating
the hb_codepoint_t to 16bits before comparison. I have no idea how
this was never discovered, and I'm too lazy to try to reproduce this
with Pango (which uses non-16bit codepoint numbers for missing glyphs).

[layout] Port sanitize() to use dispatch()

Needed some rework of Extension table. Hopefully I got it right, and

Make sanitize() a const method
...
This makes a lot of code safer. We only try modifying the object in one
place, after making sure it's safe to do so. So, do a const_cast<> in
that one place...

eb8c978547f09d368fc204194fb34688.ttf
