Also fixes a bug where glyph alternates in MTI feature files were
wrongly sorted by glyph name. After this change, the output is using
the same ordering as in the input MTI feature file.
Fixes https://github.com/fonttools/fonttools/issues/833.
When reduce() receives an empty sequence, it raises TypeError, unless it is given a third 'initializer' argument
ValueFormat values should default to 0, so we shall use that as initializer.
Also, the reduce() built-in is no longer available on Python 3.
It's still accessible for both py2 and py3 from functools.

On python2.7, the fonttools py23 module registers a 'lastResort' StreamHandler
similar to the one found in python3's logging module, that always writes
to the current value `sys.stderr`.
This also applies to any python library that imports from fontTools.misc.py23
under python2.7.
The logging module has a 'shutdown' atexit handler that flushes all the
logging handlers' streams just before the python interpreter exits.
Sometimes (e.g. when calling `python setup.py test` as in MutatorMath's test
suite), the interpreter termination ends with a traceback, which is
triggered by the atexit handler failing to flush the lastResort handler's
stream, sys.stderr
AttributeError: None has no attribute 'stderr'
This is because during module teardown, the globals (in this case 'sys')
are set to None, and the order in which modules are deleted is not
guaranteed.

We are using unicode_literals in this module since 329261b.
Because of that, on py27 sometimes a TTFont glyphOrder may end up with
a mix of `str` and `unicode` glyph names.
While I'd love to change every single 'text' string to unicode, maybe
in this case it makes sense to use the native `str` type (`bytes` on
py2, unicode string on py3) for the UV2AGL and AGL2UV dictionaries, as
glyph names can only contain ascii characters anyway.

Indentation for TTX XMLF is 2 spaces. I chose 4 spaces for indentation of instructions to make it more noticeable. I hope it’s not a problem, because assembly code lines are usually very short.
Also fixes issues with merging of PairPos.
Trying on Noto Sans Thai still fails, now because of issues in class differences in
PairPosFormat2. :( Investigating.
This is part of fixing https://github.com/fonttools/fonttools/issues/719
though, the changes are currently in interpolate_layout, and need to be ported /
merged with varLib.__init__ variation-font-builder.
We should probably use cliTools.makeOutputFileName here for consistency with ttx,
but I know some prefer the approach taken by pyftsubset so I don't want force this.
Howver, I find it a bit annoying that when one is too lazy (like me) to specify
the --output-file=, the subsetter outputs a file ending with an invalid ".subset" extension, which Finder or Windows Explorer don't recongize as a font, and so one has to rename it anyway.
This makes the '.subset' string is inserted between the file name and its original extension (if any).
The code in main() assumes that the first of the args which are not consumed by Options.parse_opts(args) is the positional argument (ie. does not start with '--') for the input font file, and that is what the usage() says too.
However I find it myself writing --options=... first, and then at the end the positional arguments, as is the convention for many other Unix tools.
This patch makes this possible, while also keeping the current behavior.
