232b2ccbc4 Move the rest of py23 module to textTools 
Change all imports to use textTools module, except the test_py23.py test
which is kept until we decide to remove the module (if ever).

000bf81700 Default to "\n" for newlinestr instead of None 
If newlinestr is None, os.linesep is used, bu it is the third millennium
and we don’t need or want different line endings per-platform.

bba5e8b213 Add optional compaction of GPOS PairPos subtables in otlLib.optimize.gpos 
See pull request: https://github.com/fonttools/fonttools/pull/2326

The new module `otlLib.optimize.gpos` provides `compact` functions that
can reduce the file size of GPOS PairPos lookups by splitting subtables
in a smart way to avoid storing zero-valued pairs.

The compaction methods are called from `otlLib.builder` and
`varLib.merger` so that static and variable fonts can benefit from the
optimization at compile time.

The new module `otlLib.optimize` is also executable, to allow running
the optimization on existing fonts.

The optimization is a trade-off because on the one hand it can reduce
significantly the byte size of the GPOS table (up to 50% in random
Google Fonts) but on the other hand it adds to the compilation time and
may make fonts very slightly bigger once compressed to WOFF2 (because
WOFF2 doesn't mind about zero values and compresses them very well).

As such, the optimization is off by default, and you can activate it by
providing the environment variable `FONTTOOLS_GPOS_COMPACT_MODE=5` for
example (values from 0 = off to 9 = max file size savings, but many more
subtables).
