Separate nil font-funcs from parent-peeking font-funcs

API change: all fonts created with hb_font_create() now inherit from
(ie have parent) hb_font_get_empty().

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.

[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.
