This reverts commit d8803873f6d4efbcb227867fe0ac6bca370597bc.
The commit wasn't fully correct as it was not installing properties
for counts in format-switching subtables.
In f0eb7e98ca0642f17ac82433db8c957fffd6a9d3, the various subclasses
of otTables.ClassDef were merged into one single class. Therefore,
we can now always instantiate otTables.ClassDef() which is simpler.
In f0eb7e98ca0642f17ac82433db8c957fffd6a9d3, the various subclasses
of otTables.Coverage were merged into one single class. Therefore,
we can now always instantiate otTables.Coverage() which is simpler.
Make the output of otlLib.buildLigatureSubst() deterministic.
Before this change, otlLib ligatures were emitted in a non-deterministic
sorting order (depending on what hash value Python would give
to a string tuple).
After b4919b6c0a5ea0ca6747fe7699554e8a14d1f77f, the tests were
named correctly but they always used the exact same feature file,
irrespective of what file they were supposed to test.

Contains the sketch and start of a stateless GSUB/GPOS/GDEF builder.
Will be used by mtiLib, feaLib, and the future voltLib. Can also
be used by clients to build these tables with much less pain.
Before, equivalent types, eg. otTables.BacktrackCoverage, etc,
where a subclass of their equivalent parent type, eg. otTables.Coverage
With this change, they are the same type.
The otBase and otConverters changes were needed to make the above
happen and still generate correct XML for SubTable type.
On Windows, some Python versions format "Jan 01" while others
format "Jan 1"; this caused test failures on the build farm.
By using a date without leading zeros (2011-12-13), we can
work around this.

Before this change, feaLib did not handle feature files that specified
`feature aalt` whose block just was referring to other features without
defining any lookups on its own. After this change, we can handle it.

Python's stdlib
The 'xml.parsers.expat' module has been a part of Python's Standard Library since version 2.0. Link: https://docs.python.org/2/library/pyexpat.html#module-xml.parsers.expat . FontTools requires Python 2.7, or Python 3.3 or later. Checking for the existence of this module is not necessary anymore.
The code for building GDEF tables had grown quite a bit, so it was
hard to understand what was going on. After this change, each GDEF
subtable gets built by a separate method. This increases legibility.
