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.

Previous overflow test was inadequate.

98a627dc03 py: Add "io" module. 
So far just includes "open" function, which should be supplied by a port.

TODO: Make the module #ifdef'ed.

baf6f14deb Enhance str.format support 
This adds support for almost everything (the comma isn't currently
supported).

The "unspecified" type with floats also doesn't behave exactly like
python.

Tested under unix with float and double
Spot tested on stmhal

caac542b23 Proper support for registering builtin modules in ROM. 
Comes with some refactoring of code and renaming of files.  All modules
are now named mod*.[ch].

8bfec2b538 Rename formatfloat file; remove MICROPY_ENABLE_FLOAT from mpconfigport.h. 
MICROPY_ENABLE_FLOAT is automatically set in mpconfig.h if MICROPY_FLOAT_IMPL
is set to a non-zero value.

0c36da0b59 Implement ROMable modules. Add math module. 
mp_module_obj_t can now be put in ROM.

Configuration of float type is now similar to longint: can now choose
none, float or double as the implementation.

math module has basic math functions.  For STM port, these are not yet
implemented (they are just stub functions).

06201ff3d6 py: Implement bit-shift and not operations for mpz. 
Implement not, shl and shr in mpz library.  Add function to create mpzs
on the stack, used for memory efficiency when rhs is a small int.
Factor out code to parse base-prefix of number into a dedicated function.

438c88dd2f Add arbitrary precision integer support. 
Some functionality is still missing (eg and, or, bit shift), and some
things are buggy (eg subtract).

c5966128c7 Implement proper exception type hierarchy. 
Each built-in exception is now a type, with base type BaseException.
C exceptions are created by passing a pointer to the exception type to
make an instance of.  When raising an exception from the VM, an
instance is created automatically if an exception type is raised (as
opposed to an exception instance).

Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.

Handling of parse error changed to match new exceptions.

mp_const_type renamed to mp_type_type for consistency.

8bc3516389 ffi: Implement ffivar.get()/set() methods. 
Done by introducing another factored out helper API in binary.c. This API
can be reused also by array and struct modules.

440cc3f028 Expose memory stats functions via "micropython" module. 
These are micropython.mem_total(), .mem_current(), .mem_peak(). These are 3
individual functions with simple scalar return value to make sure that
calls to these functions themselves have minimal (hopefully zero) impact on
memory allocation.

427905cedd Add skeleton implementation of array.array and bytearray. 
So far, only storage, initialization, repr() and buffer protocol is
implemented - alredy suitable for passing binary data around.

062478e66d Improved type/class/instance code; mp_obj_type_t now has load_attr, store_attr. 
Creating of classes (types) and instances is much more like CPython now.
You can use "type('name', (), {...})" to create classes.
