39bd07aed5 Fix bunch of unused parameter warnings 
Show up with gcc -O0.

There's a few more but those are functions that need to be filled in.

Maybe this is a lost battle...

2995b4465b [CBDT] Simplify sanitize 2018-10-14 20:37:57 -07:00
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.
