[otlLib] Refactor chained contextual builders (#2007)
* Introduce a new subclass for chained contextual (sub and pos)

* Rename .substitutions to .rules in subst builders to allow for code reuse

* Make format of subtable break marker tuple common between sub/pos

Note that prior to this patch, add_subtable_break in a Subst builder adds:

(self.SUBTABLE_BREAK_, self.SUBTABLE_BREAK_, self.SUBTABLE_BREAK_, self.SUBTABLE_BREAK_)

while add_subtable_break in a Pos builder adds:

(self.SUBTABLE_BREAK_, self.SUBTABLE_BREAK_, self.SUBTABLE_BREAK_, [self.SUBTABLE_BREAK_])

This is messy. If we read the first element from the tuple instead of the last one to test if a rule is a subtable break, we can make the marker tuple the same.

* And now the subtable break code can be hoisted into superclass

* These helper methods will make the build routine common

* Hoist common build method to superclass

The diff doesn’t show it very clearly because it’s being too clever, but all I’ve done is moved one method. Everything works apart from the error message, which comes next.

* Fix the error message

Move feature builders to otlLib
Refactors feaLib, moving code which builds OpenType lookups into otlLib. Note that this changes feaLib's concept of `location` from a tuple to an object.

Fix for #1985: ensure that the AxisNameID in the STAT table is > 255 (#1986)
Fix for #1985:
* ensure that the AxisNameID in the STAT table is not less than 256. This needed an additional argument to the addMultiLingualName() name table method.
* fvar axis name IDs must also not be less than 256, just like STAT axis names.

[otlLib.builder] Add function to build STAT table from high-level description (#1926)
* added a function to build a STAT table: `fontTools.otlLib.builder.buildStatTable()`
* make `varLib._add_stat()` a client of `buildStatTable()`

b44c761526 [oltLib.builder] Fix bug in building a variation font.
The logic for building a Device subtable didn't know about the VariationIndex flavor of a ValueRecord Device subtable.

45596108e2 (Re)calculate OS/2.usMaxContext value
The value is only modified in the context of fontBuilder or subset. It will NOT be modified when using ttx.

maxContextCalc.py was copied from https://github.com/googlefonts/ufo2ft/blob/master/Lib/ufo2ft/maxContextCalc.py

Fixes #1191
Fixes #466

consistently do sys.exit(unittest.main()) in all test modules
So that when run as scrips they report test failures with exit code

0f609592bb [otlLib] Build multiple glyph-based PairPos subtables when needed
Before this change, feaLib would group glyph-based pair positionings
by value formats. After this change, this logic happens in otlLib.
But clients can still do their own grouping if they wish, by calling
the buildPairPosGlyphsSubtable() method directly.

These count attrs are redundant and we might remove them in the
future.  To simplify things, always write them as:

59ee0618d7 [otlLib] Explicitly set Value to None if needed
Although the compiler (and now XML writer) assume None if an attribute
is not set, it's extremely frustrating for other code to have to check
before accessing an attribute.  So, explicitly set please!
