e299650f9f [varStore] In OnlikeVarStoreBuilder, dedup items 
While we optimize VarStore later, just deduping here reduces amount
of data we have to work with later by 8x in NotoSans-VF.ttf test
case.  It's a cheap optimization, so do it.

[varStore] don't import unicode_literals 
Tests were failing on python 2.7.6 because array module doesn't accept
unicode strings (fixed in later 2.7.x releases).

An alternative fix would have been to cast array(str('h'), [...]) but
that seemed a bit too much, especially since varStore module doesn't
really do heavy text manipulation (there aren't other string literals).

We cannot use unicode_literals unconditionally, because of this and
similar issues in the stdlib. We should use it only when it makes sense
and reduces the frequency of u"".

d46d40dc9e [varLib] Actually remove duplicates while optimizing VarStore! 
Ouch!  Shrinks NotoSans-VF.ttf GDEF VarStore further down.
Original was 1016278 bytes. Before this change it was optimizing
to 256145 bytes. With this change, it goes down to a mere 57127
bytes!!!

- AxisOrdering is set to the order axes are defined,
- Name-table entries are not shared with fvar.

28bb992c1f replace int(round(...)) with round(...) 
We don't need to cast to int when using the round function from py23,
as this is a backport of python3's built-in round and thus it returns
an int when called with a single argument.

5eb3cbe2b0 [varLib.mutator] Mutate GPOS 
Cleans up GDEF varstore as well.

What's left:

- In none of the varLib.merger Mergers we handle the CaretValueFormat3. That should be done,
  even though no one uses this,

- GPOS/GSUB FeatureVariations are not applied.  Shouldn't be hard.

- 'rvrn' should be folded into 'ccmp' or some other default feature.
