varLib.merger: simplify if-stmt logic a bit 
isPairPos and isSinglePos are mutually exclusive and isSinglePos is only defined if isPairPos is False
so it is safe to use it in 'else' or 'elif' branches (logical expressions short-circuit)

varLib.merger: when flattening singlepos, copy valuerecords

b756bcac18 [varLib.merger] Fix merging GPOS SinglePos subtables 
When a SinglePost lookup is compiled, pretty much all compilers do some compression by combining similar ValueRecords into a single subtable. This compression produces different lengths of the list of subtables between source fonts. The original code required that all SinglePos lookups have the same subtables, often doesn't work.

I fixed this in varLib.merger.py by first flattening a SinglePos lookup to a single subtable, using the same record format for all records, and then merging the source fonts. After the merge is complete, I call fontTools.otlLib.builder.buildSinglePos() to rebuild the lookup subtables.

7e5644a0a8 [varLib] Fix merging GDEF.GlyphClassDef in mutator 
The code was setting GlyphClassDef.classDefs for the base font to an
empty dict then reading it from all fonts. It accidentally works when
creating variable fonts because the GlyphClassDef of the other fonts
will be used, but when mutating there is only one font.

Fix by reading the glyph classes before assigning to an empty dict.

8e080f2a82 [varLib] Fix merging of multiple PairPosFormat2 subtables 
We should invert each ClassDef1 against its own sublookup Coverage,
not the combined one.  Oops!

479b52e13d [varLib] When merging MarkBasePos, retain original coverage objects 
Just such that their existing .Format is preserved, as that is written out
to the XML file, and would break the test suite if not there.

Stupid to write Coverage Format to XML.  Oh well...

37dd59120b [varLib] Allow merging sparse ClassDefs 
This is mainly meant for GDEF.GlyphClassDefs, but implementation is on the
ClassDefs type.  What can possibly go wrong...  Seriously though, this is
pretty much always what is desired.  To be embraced by more type mergers
down the road.
