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.

Make some of implicit header uses explicit (#989)
Splitted from #950 and #986 IIRC Chromium had a policy about this encouraging it,
not sure about automated way to detect and add them but for now lets have the needed
ones of them.

Behdad Esfahbod f0bc6c0992 [aat/trak] Clean up
We always just used "unsigned int" for counter values. There's
no use for uint16_t outside of a struct.

Also, no need for explict casting where implicit does.

Maybe we should make DEFINE_* make structs uncopyable.
