0c8fcb9c49 py: Remove silly comment about interning keywords. 
Of course, keywords are turned into lexer tokens in the lexer, so will
never need to be interned (unless you do something like x="def").

As it is now, the following on pyboard makes no new qstrs:

    import pyb
    pyb.info()

27f5bdd6d4 py: "read" & "write" are so common that make them core. 
Few other strings move to core, but make depend on "io" module.

bbae42d62f modsys: Implement sys.version. 
The logic appears to be that (at least beginning of) sys.versions is the
version of reference Python language implemented, not version of particular
implementation.

Also, bump set versions at 3.4.0, based on @dpgeorge preference.

48fdaad824 py: Rename collections module to _collections. 
We're not going to implement all the plethora of types in there in C.
Funnily, CPython implements defaultdict in C, and namedtuple in Python.

These largely duplicate str() & bytes() constructors' functionality,
but can be used to achieve Python2 compatibility.

13d52df4c5 builtinimport: Set __path__ attribute on packages. 
Per https://docs.python.org/3.3/reference/import.html , this is the way to
tell module from package: "Specifically, any module that contains a __path__
attribute is considered a package." And it for sure will be needed to
implement relative imports.

a925cb54f1 py: Preprocess qstrdefs.h before feeding to makeqstrdata.py. 
This is alternative implementation of supporting conditionals in qstrdefs.h,
hard to say if it's much cleaner than munging #ifdef's in Python code...

e9db840480 py: Start implementing "struct" module. 
Only calcsize() and unpack() functions provided so far, for little-endian
byte order. Format strings don't support repition spec (like "2b3i").

Unfortunately, dealing with all the various binary type sizes and alignments
will lead to quite a bloated "binary" helper functions  - if optimizing for
speed. Need to think if using dynamic parametrized algos makes more sense.

a985b4593d objint: Implement int.from_bytes() class method and .to_bytes() method. 
These two are apprerently the most concise and efficient way to convert
int to/from bytes in Python. The alternatives are struct and array modules,
but methods using them are more verbose in Python code and less efficient
in memory/cycles.

27e735fd18 py: Replace stream_p with *stream_p in mp_obj_type_t. 
This is to reduce ROM usage.  stream_p is used in file and socket types
only (at the moment), so seems a good idea to make the protocol
functions a pointer instead of the actual structure.

It saves 308 bytes of ROM in the stmhal/ port, 928 in unix/.

e44d26ae0c py: Implement __getattr__. 
It's not completely satisfactory, because a failed call to __getattr__
should not raise an exception.

__setattr__ could be implemented, but it would slow down all stores to a
user created object.  Need to implement some caching system.
