65402ab1ec py/mpz: Do Python style division/modulo within bignum divmod routine. 
This patch consolidates the Python logic for division/modulo to one place
within the bignum code.

dc3faea040 py/mpz: Fix bug with overflowing C-shift in division routine. 
When DIG_SIZE=32, a uint32_t is used to store limbs, and no normalisation
is needed because the MSB is already set, then there will be left and
right shifts (in C) by 32 of a 32-bit variable, leading to undefined
behaviour.  This patch fixes this bug.

12dd8df375 py/objstr: Binary type of str/bytes for buffer protocol is 'B'. 
The type is an unsigned 8-bit value, since bytes objects are exactly
that.  And it's also sensible for unicode strings to return unsigned
values when accessed in a byte-wise manner (CPython does not allow this).

ab69ed7dac tests: Split large tests into smaller files, to run with a small heap. 
All tests in basics/ directory can now run and pass using 64-bit unix
port with only a 16k heap (./run-tests --heapsize 16k).  Tests in this
directory should remain small so they can be used for ports with a
small heap.

2e2e15cec2 py/mpz: Complete implementation of mpz_{and,or,xor} for negative args. 
For these 3 bitwise operations there are now fast functions for
positive-only arguments, and general functions for arbitrary sign
arguments (the fast functions are the existing implementation).

By default the fast functions are not used (to save space) and instead
the general functions are used for all operations.

Enable MICROPY_OPT_MPZ_BITWISE to use the fast functions for positive
arguments.

f8ba2eca80 builtin property: accept keyword arguments 
this allows python code to use property(lambda:..., doc=...) idiom.

actually needed.

78913211a9 py: Be more restrictive binding self when looking up instance attrs. 
When looking up and extracting an attribute of an instance, some
attributes must bind self as the first argument to make a working method
call.  Previously to this patch, any attribute that was callable had self
bound as the first argument.  But Python specs require the check to be
more restrictive, and only functions, closures and generators should have
self bound as the first argument

06593fb0f2 py: Use a wrapper to explicitly check self argument of builtin methods. 
Previous to this patch a call such as list.append(1, 2) would lead to a
seg fault.  This is because list.append is a builtin method and the first
argument to such methods is always assumed to have the correct type.

Now, when a builtin method is extracted like this it is wrapped in a
checker object which checks the the type of the first argument before
calling the builtin function.

This feature is contrelled by MICROPY_BUILTIN_METHOD_CHECK_SELF_ARG and
is enabled by default.

See issue #1216.

Damien George
c2a4e4effc py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function. 
Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as
the operator argument.  Hashing for int, str and bytes still go via
fast-path in mp_unary_op since they are the most common objects which
need to be hashed.

This lead to quite a bit of code cleanup, and should be more efficient
if anything.  It saves 176 bytes code space on Thumb2, and 360 bytes on
x86.

The only loss is that the error message "unhashable type" is now the
more generic "unsupported type for __hash__".

7d414a1b52 py: Parse big-int/float/imag constants directly in parser. 
Previous to this patch, a big-int, float or imag constant was interned
(made into a qstr) and then parsed at runtime to create an object each
time it was needed.  This is wasteful in RAM and not efficient.  Now,
these constants are parsed straight away in the parser and turned into
objects.  This allows constants with large numbers of digits (so
addresses issue #1103) and takes us a step closer to #722.

1e1779eacf py: Reluctantly add an extra pass to bytecode compiler. 
Bytecode also needs a pass to compute the stack size.  This is because
the state size of the bytecode function is encoded as a variable uint,
so we must know the value of this uint before we encode it (otherwise
the size of the generated code changes from one pass to the next).

Having an entire pass for this seems wasteful (in time).  Alternative is
to allocate fixed space for the state size (would need 3-4 bytes to be
general, when 1 byte is usually sufficient) which uses a bit of extra
RAM per bytecode function, and makes the code less elegant in places
where this uint is encoded/decoded.

So, for now, opt for an extra pass.

4c81ba8015 py: Never intern data of large string/bytes object; add relevant tests. 
Previously to this patch all constant string/bytes objects were
interned by the compiler, and this lead to crashes when the qstr was too
long (noticeable now that qstr length storage defaults to 1 byte).

With this patch, long string/bytes objects are never interned, and are
referenced directly as constant objects within generated code using
load_const_obj.

78d702c300 py: Allow builtins to be overridden. 
This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
which, when enabled, allows to override all names within the builtins
module.  A builtins override dict is created the first time the user
assigns to a name in the builtins model, and then that dict is searched
first on subsequent lookups.  Note that this implementation doesn't
allow deleting of names.

This patch also does some refactoring of builtins code, creating the
modbuiltins.c file.

9a21d2e070 py: Make mpz able to use 16 bits per digit; and 32 on 64-bit arch. 
Previously, mpz was restricted to using at most 15 bits in each digit,
where a digit was a uint16_t.

With this patch, mpz can use all 16 bits in the uint16_t (improvement
to mpn_div was required).  This gives small inprovements in speed and
RAM usage.  It also yields savings in ROM code size because all of the
digit masking operations become no-ops.

Also, mpz can now use a uint32_t as the digit type, and hence use 32
bits per digit.  This will give decent improvements in mpz speed on
64-bit machines.

Test for big integer division added.

ea9708092e objtuple: Go out of the way to support comparison of subclasses. 
Two things are handled here: allow to compare native subtypes of tuple,
e.g. namedtuple (TODO: should compare type too, currently compared
duck-typedly by content). Secondly, allow user sunclasses of tuples
(and its subtypes) be compared either. "Magic" I did previously in
objtype.c covers only one argument (lhs is many), so we're in trouble
when lhs is native type - there's no other option besides handling
rhs in special manner. Fortunately, this patch outlines approach with
fast path for native types.

d86020ac4f objtype: Don't treat inheritance from "object" as from native type. 
"object" type in MicroPython currently doesn't implement any methods, and
hopefully, we'll try to stay like that for as long as possible. Even if we
have to add something eventually, look up from there might be handled in
adhoc manner, as last resort (that's not compliant with Python3 MRO, but
we're already non-compliant). Hence: 1) no need to spend type trying to
lookup anything in object; 2) no need to allocate subobject when explicitly
inheriting from object; 3) and having multiple bases inheriting from object
is not a case of incompatible multiple inheritance.

0c904df8e6 vm: Save current active exception on opening new try block. 
Required to reraise correct exceptions in except block, regardless if more
try blocks with active exceptions happen in the same except block.

P.S. This "automagic reraise" appears to be quite wasteful feature of Python
- we need to save pending exception just in case it *might* be reraised.
Instead, programmer could explcitly capture exception to a variable using
"except ... as var", and reraise that. So, consider disabling argless raise
support as an optimization.
