d801056100 [varLib] Allow merging of class-based kerning when ClassDef1's are different

that failed so far.

dc07fe4f8f [varLib] Allow merging of class-based kerning when ClassDef2's are different 
With this, we can build varfont for NotoSansThai and a couple more.

This is the first use of fontTools.misc.classifyTools module.

[varLib.merger] set initializer for reduce() to handle empty sequences; import reduce from functools for py3 
When reduce() receives an empty sequence, it raises TypeError, unless it is given a third 'initializer' argument

ValueFormat values should default to 0, so we shall use that as initializer.

Also, the reduce() built-in is no longer available on Python 3.
It's still accessible for both py2 and py3 from functools.

VariationMerger now has all the intelligence of AligningMerge.
Should be good for a while...
