Behdad Esfahbod 7fd0b61dee [subset] Create new face and copy all tables to it

compile itself into a font blob.

Behdad Esfahbod 2da0d87e76 Remove NullPool visibility hack 
We keep a separate private NullPool in libharfbuzz-subset.so
This can fire back later since now there are two separate null objects,
and comparisons to the null pool can be confused.  Something to deal
with when it comes up. Ouch!
