David Lechner 783b1a868f py/runtime: Allow multiple *args in a function call.
This is a partial implementation of PEP 448 to allow unpacking multiple
star args in a function or method call.

This is implemented by changing the emitted bytecodes so that both
positional args and star args are stored as positional args.  A bitmap is
added to indicate if an argument at a given position is a positional
argument or a star arg.

In the generated code, this new bitmap takes the place of the old star arg.
It is stored as a small int, so this means only the first N arguments can
be star args where N is the number of bits in a small int.

The runtime is modified to interpret this new bytecode format while still
trying to perform as few memory reallocations as possible.

David Lechner eadc927baf docs/differences/python_35: Mark PEP 486 as not applicable.
This adds the "Not relevant" designation to PEP 486 since it has to do with
the Python Launcher for Windows and not the Python language itself.

Also fix a typo while we are touching this line.

NitiKaur 01953f2964 docs/differences: Document details of new PEPs/features in Python 3.5+.
And how they relate to MicroPython.  As these features are implemented (or
the decision is made to not implement them) the tables can be updated to
document the differences between MicroPython and standard Python.

Paul Sokolovsky 8b7d311595 reference/index: Rewrite introduction paragraph to avoid confusion.
The old intro talked about "differences", but there were hardly any
sections describing differences, mostly MicroPython specific features.
On the other hand, we now have real "differences" chapter, though it's
mostly concerned with stdlib differences.

So, try to avoid confusion by changing wording and linking to the other
chapters and contrasting them with what is described in "MicroPython
language".

Paul Sokolovsky 50eea26145 docs/differences/index_template: Use consistent heading casing.
And in our case, "consistent" is where each word in the heading is *not*
capitalized.

Rami Ali b7fa63c7ce tools: Add gen-cpydiff.py to generate docs differences.
This patch introduces the a small framework to track differences between
uPy and CPython.  The framework consists of:

- A set of "tests" which test for an individual feature that differs between
  uPy and CPy.  Each test is like a normal uPy test in the test suite, but
  has a special comment at the start with some meta-data: a category (eg
  syntax, core language), a human-readable description of the difference, a
  cause, and a workaround.  Following the meta-data there is a short code
  snippet which demonstrates the difference.  See tests/cpydiff directory
  for the initial set of tests.

- A program (this patch) which runs all the tests (on uPy and CPy) and
  generates nicely-formated .rst documenting the differences.

- Integration into the docs build so that everything is automatic, and the
  differences appear in a way that is easy for users to read/reference (see
  latter commits).

The idea with using this new framework is:

- When a new difference is found it's easy to write a short test for it,
  along with a description, and add it to the existing ones.  It's also easy
  for contributors to submit tests for differences they find.

- When something is no longer different the tool will give an error and
  difference can be removed (or promoted to a proper feature test).
