* Implement glyf outline flags bit 6 when decompiling/compiling
* Add test data for outline flag bit 6
* Rename flags, use bitwise OR for setting flag bit
* Remove unneeded code
So we now round towards +Infinity in:
- floatToFixed (which fully examplify that quotes from OT spec)
- psCharStrings: when packing floats as fixed 16.16
- t2CharStringPen: when rounding coordinates and advance widths
- subset: when rounding advance widths to compute average
- TupleVariation: rounding gvar deltas
- _g_l_y_f: when rounding coordinates: both in GlyphComponent.{x,y}
and for GlyphCoordinates.toInt()
- _h_m_t_x: for rounding horiz/vert metrics
- varLib: rounding horiz metrics and deltas
in _checkFloat (used whenever we're about to update the inner array) we check whether the value exceeds a short integer, and if so we convert the array to floats.
Also, we make sure we call __setitem__ (which in turn calls _checkFloat) instead of updating the inner array directly in the rest of the math methods.
The split-glyf-to-one-glyph-per-file feature is only partially implemented,
as it was discussed here:
https://github.com/fonttools/fonttools/issues/153#issuecomment-346677171
I need to cut a bugfix release today, but I don't want to ship this as is.
I prefer to temporarily rever, tag a release from master branch, then
revert it again to its present state so that bamidei can complete his
work.

We don't need to cast to int when using the round function from py23,
as this is a backport of python3's built-in round and thus it returns
an int when called with a single argument.
it might be deprecated or ignored in some rasterizers, but I don't
see why we should discard it, if it's present in the input font.
This also allows to set the flag, which may turn out to be useful
in some circumstances.
cf. https://github.com/googlei18n/fontmake/issues/253#issuecomment-335600887
otherwise `not NotImplemented` (always False) is returned from __ne__ when `type(self) != type(other)`, leading to illogic results like:
>>> from fontTools.ttLib.tables.DefaultTable import DefaultTable
>>> t = DefaultTable('test')
>>> t == 0
False
>>> t != 0
False
The latter of course should return True.
