cc83737d35 Don't allow both ENDIANNESSes to be set 
See discussion on 2da81fa80c

Explicitly set `MP_ENDIANNESS_LITTLE` because that's the #define that is used in code elsewhere.

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.

58676fc2c7 objstr: Allow to define statically allocated str objects. 
Similar to tuples, lists, dicts. Statically allocated strings don't have hash

59e269cfec qstr, objstr: Make sure that valid hash != 0, treat 0 as "not computed". 
This feature was proposed with initial hashing RFC, and is prerequisite for
seamless static str object definition.

df8127a17e py: Remove unique_codes from emitglue.c. Replace with pointers. 
Attempt to address issue #386.  unique_code_id's have been removed and
replaced with a pointer to the "raw code" information.  This pointer is
stored in the actual byte code (aligned, so the GC can trace it), so
that raw code (ie byte code, native code and inline assembler) is kept
only for as long as it is needed.  In memory it's now like a tree: the
outer module's byte code points directly to its children's raw code.  So
when the outer code gets freed, if there are no remaining functions that
need the raw code, then the children's code gets freed as well.

This is pretty much like CPython does it, except that CPython stores
indexes in the byte code rather than machine pointers.  These indices
index the per-function constant table in order to find the relevant
code.

Improved the Thumb assembler back end.  Added many more Thumb
instructions to the inline assembler.  Improved parsing of assembler
instructions and arguments.  Assembler functions can now be passed the
address of any object that supports the buffer protocol (to get the
address of the buffer).  Added an example of how to sum numbers from
an array in assembler.

type.binary_op directly, they should always go through mp_binary_op
(or mp_obj_is_equal).

69b89d21b2 py: Change compile order for default positional and keyword args. 
This simplifies the compiler a little, since now it can do 1 pass over
a function declaration, to determine default arguments.  I would have
done this originally, but CPython 3.3 somehow had the default keyword
args compiled before the default position args (even though they appear
in the other order in the text of the script), and I thought it was
important to have the same order of execution when evaluating default
arguments.  CPython 3.4 has changed the order to the more obvious one,
so we can also change.

57e99ebc86 py: Add simple way of looking up constants in compiler. 
Working towards trying to support compile-time constants (see discussion
in issue #227), this patch allows the compiler to look inside arbitrary
uPy objects at compile time.  The objects to search are given by the
macro MICROPY_EXTRA_CONSTANTS (so they must be constant/ROM objects),
and the constant folding occures on forms base.attr (both base and attr
must be id's).

It works, but it breaks strict CPython compatibility, since the lookup
will succeed even without importing the namespace.
