Normalize various spaces to space if font doesn't support
...
This resurrects the space fallback feature, after I disabled
the compatibility decomposition. Now I can release HarfBuzz
again without breaking Pango!
It also remembers which space character it was, such that later
on we can approximate the width of this particular space
character. That part is not implemented yet.
We normalize all GC=Zs chars except for U+1680 OGHA SPACE MARK,
which is better left alone.

Good thing we have ongoing fuzzing going now. Was discovered
immediately by libFuzzer. Thanks kcc!

[util] In --debug mode, duplicate font data
...
This has the effect that the font data will end up in a memory
section malloc()ed exactly to its size. This gives us better
valgrind detection of out-of-bounds access.
Previously, the font data was placed in a mmap()ed section or
GString-allocated area, which didn't have proper protections
at the end when running under valgrind.

We probably should implement better system to catch cyclic lookups.
But for now, this speeds up worst case behavior with broken fonts
considerably without compromising legitimate usecases.
