a364f60d1d [feaLib] Change semantics of markClass to also define a glyphclass 
While not really documented in the OpenType Feature File specification,
the AFDKO makeotf tool handles the `markClass` statement this way.
Also, some examples in the specification seem to imply this semantics.

d622f99982 [feaLib] Clean up class names of Abstract Syntax Tree statements 
The class names of tree nodes for substitution and positioning rules
are now consistent with `builder.py`, which in turn is consistent with
`otTables.py`.

5b1b1d17f6 [feaLib] Restructure MarkBasePosBuilder in preparation of MarkLigPosBuilder 
The upcoming MarkLigPosBuilder will have some parts in common with
MarkBasePosBuilder. Move these common parts into a helper method,
so that MarkLigPosBuilder will be able to call them.

Also, clean up the structure of MarkBasePosBuilder.

25acebd824 [feaLib] Minor parser refactoring in preparation for GPOS type 5 
GPOS type 5 has much in common with GPOS type 4, so we want to share
the common parsing code.

8128b509a4 [subset] Augment ContextHelper 
As needed in my Monotype OpenType format parser.  I'm not using the object
directly from subset module, but pushing back my changes here, in the hope
that we move this object to ttLib proper soon.

off any device values. Left a TODO comment for implementing this.

f45fab8c3a [feaLib] Sort GSUB glyph coverage tables by glyph ID 
Before this change, feaLib would sort coverage tables by glyph name,
which is against the OpenType specification.  The current unittests
happen to use only glyphs where the ordering is identical whether
sorting by name or by ID; but I am about to add unittests (for GPOS)
where the ordering is different.

The ordering cannot be enforced by otTables because otTables does
not have access to the font's glyph order; therefore, the sorting
needs to happen inside feaLib.
