AIX fixes
...
- use '-w' instead of '\<...\>' for check-header-guards
grep manpage says these are the same
- put '-q' first in the grep options
- move VAR into hb-private.hh
- hb-font-private.hh - use [VAR] instead of [] for variable array

[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).

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...
