* Replaced all from ...py23 import * with explicit name imports, or removed completely when possible.
* Replaced tounicode() with tostr()
* Changed all BytesIO ans StringIO imports to from io import ..., replaced all UnicodeIO with StringIO.
* Replaced all unichr() with chr()
* Misc minor tweaks and fixes
Note UI change : `fonttools varLib.models` now takes prefixed options `-d` or `-l` instead of guessing the intended feature from the number of arguments.
We have a number of command line tools which are somewhat opaque. (varLib.models in particular was very confusing.) This ensures that they all use argparse to have a consistent interface, and all have --help documentation which at least details their parameters, and hopefully therefore gives more of a clue about what they do. Those which use logging have had a command-line logging parameter added.
This adds a `help` verb (and `--help` option) to the `fonttools` command line tool. Submodules will be listed in the help text if they have an importable `main` function with a docstring, and `main`'s docstring will be used as the one-line description for the help text.
The convention is that sys.exit(...) is called only if a module is run as a script,
and that main() entry points use return statements to report exit codes: 0 (or None)
for successful execution, or any non-zero integer for errors.
E.g. see the console scripts generated when installing with pip.
If a module is run as script, as in `python module.py` or when using
`runpy.run_module()`, then __name__ == "__main__".
So when we instantiate modules' loggers with `logging.getLogger(__name__)`,
those loggers' name may become "__main__" when run as scripts, and hence
fall outside of the "fontTools" logging namespace.
fontTools.configureLogger() by default only configures the "fontTools"
library loggers, anything outside of it (e.g. logger called "__main__")
is not attached a handler.
So here I name loggers explicitly instead of relying on __name__, but
only for modules which can be run as "__main__".

The following sed command can be used to update TTX sources for the LookupType
change:
$ sed -i'~' 's/<!-- LookupType=\(.\) -->/<LookupType value="\1"\/>/g' *.ttx
Tests pass on both Python 2 and 3 now. Yay!
MockFont is handy for mtiLib.__init__:main(). Not sure how useful it is
otherwise, and what to replace it with.
I'll first make Python 2 and 3 both generate same output for tests with
MockFont, then will probably hardcode glyphorder and remove MockFont
completely and remove hacks I added to make tests work with MockFont.
