Thanks Zachary for reporting this

SFNTReader: define __getstate__/__setstate__ to reopen external file 
Instead of copying to BytesIO, we can return the file name in getstate and reopen the file in setstate. This keeps the TTFont truly lazy as it avoids the extra copy

sfnt: custom __deepcopy__ not needed with __getstate__ 
also, we only need to copy file to stream when self.file is _not_ already an io.BytesIO.

[sfnt] allways copy file data to BytesIO, not just if deepcopy failed 
on py27, calling deepcopy on a file object doesn't raise TypeError, but leaves
the duplicated file object in an inconsistent state:

https://travis-ci.org/fonttools/fonttools/jobs/474811063#L714

any operations on it will fail with 'ValueError: I/O operation on uninitialized object'.
Thus, for semplicity for now we always do a manual copy the file contents into an
in-memory BytesIO stream, rather than attempting to call deepcopy first.

9e6ef94b55 Use "is None" instead of "== None" 
The latter hits the __eq__ method and can fail because we now
do not allow comparing objects of different types.

For example, was failing subsetting Andika-R.ttf.
