882b363564 py: Move to Python 3.4.0 compatibility. 
Very little has changed.  In Python 3.4 they removed the opcode
STORE_LOCALS, but in Micro Python we only ever used this for CPython
compatibility, so it was a trivial thing to remove.  It also allowed to
clean up some dead code (eg the 0xdeadbeef in class construction), and
now class builders use 1 less stack word.

Python 3.4.0 introduced the LOAD_CLASSDEREF opcode, which I have not
yet understood.  Still, all tests (apart from bytecode test) still pass.
Bytecode tests needs some more attention, but they are not that
important anymore.

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

b509f73982 objtype: Wrap .__name__ handling in MICROPY_CPYTHON_COMPAT. 
Because it's runtime reflection feature, not required for many apps.
Rant time:
Python could really use better str() vs repr() distinction, for example,
repr(type) could be "<class 'foo'>" (as it is now), and str(type) just
"foo". But alas, getting straight name requires adhoc attribute.

7da0660516 mp_resume: Dare to pass send_value of NULL. 
There was thinkos that either send_value or throw_value is specified, but
there were cases with both. Note that send_value is pushed onto generator's
stack - but that's probably only good, because if we throw exception into
gen, it should not ever use send_value, and that will be just extra "assert".

a2109d9321 mp_resume: Elaborate handling of .throw() for objects which lack it. 
In this case, the exception is just re-thrown - the ideas is that object
doesn't handle this exception specially, so it will propagated per Python
semantics.

817e76a1a5 objgenerator.throw(GeneratorExit) is not equivalent to .close(). 
.throw() propagates any exceptions, and .close() swallows them. Yielding
in reponse to .throw(GeneratorExit) is still fatal, and we need to
handle it for .throw() case separately (previously it was handled only
for .close() case).

Obscure corner cases due to test_pep380.py.

a96d3d0840 objexcept: No more magic messages in exceptions, only exception arguments. 
One of the reason for separate "message" (besides still unfulfilled desire to
optimize memory usage) was apparent special handling of exception with
messages by CPython. Well, the message is still just an exception argument,
it just printed specially. Implement that with PRINT_EXC printing format.

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.

bee17b00e3 py: Put n_state for bytecode in the bytecode prelude. 
Rationale: setting up the stack (state for locals and exceptions) is
really part of the "code", it's the prelude of the function.  For
example, native code adjusts the stack pointer on entry to the function.
Native code doesn't need to know n_state for any other reason.  So
putting the state size in the bytecode prelude is sensible.

It reduced ROM usage on STM by about 30 bytes :)  And makes it easier to
pass information about the bytecode between functions.

9b196cddab Remove mp_obj_type_t.methods entry and use .locals_dict instead. 
Originally, .methods was used for methods in a ROM class, and
locals_dict for methods in a user-created class.  That distinction is
unnecessary, and we can use locals_dict for ROM classes now that we have
ROMable maps.

This removes an entry in the bloated mp_obj_type_t struct, saving a word
for each ROM object and each RAM object.  ROM objects that have a
methods table (now a locals_dict) need an extra word in total (removed
the methods pointer (1 word), no longer need the sentinel (2 words), but
now need an mp_obj_dict_t wrapper (4 words)).  But RAM objects save a
word because they never used the methods entry.

Overall the ROM usage is down by a few hundred bytes, and RAM usage is
down 1 word per user-defined type/class.

There is less code (no need to check 2 tables), and now consistent with
the way ROM modules have their tables initialised.

Efficiency is very close to equivaluent.

2613ffde43 py: Rename strtonum to mp_strtonum. 
strtonum clashes with BSD function of same name, and our version is
different so warrants a unique name.  Addresses Issue #305.

bbf0e2fe12 parse: Note that fact that parser's small ints are different than VM small int. 
Specifically, VM's small ints are 31 bit, while parser's only 28. There's already
MP_OBJ_FITS_SMALL_INT(), so, for clarity, rename MP_FIT_SMALL_INT() to
MP_PARSE_FITS_SMALL_INT().

a8d31b28bc emitbc: Correct buffer sizes for varlen int encoding. 
Assuming we have truncating (floor) division, way to do ceiling division
by N is to use formula (x + (N-1)) / N. Specifically, 63 bits, if stored
7 bits per byte, require exactly 9 bytes. 64 bits overflow that and require
10 bytes.

http://docs.python.org/3.3/library/functions.html#__import__ :
"When the name variable is of the form package.module, normally, the
top-level package (the name up till the first dot) is returned, not
the module named by name. However, when a non-empty fromlist argument
is given, the module named by name is returned."

51dabac096 Add pin mapping code. 
This commit also introduces board directories and moves board
specific config into the appropriate board directory.

boards/stm32f4xx-af.csv was extracted from the STM32F4xx datasheet
and hand-tweaked.

make-pins.py takes boards/stm32f4xx-af.csv, boards/stm32f4xx-prefix.c,
and boards/BOARD-NAME/pins.csv as input and generates the file
build/pins_BOARD_NAME.c

The generated pin file for PYBOARD4 looks like this:
https://gist.github.com/dhylands/9063231

The generated pins file includes all of the supported alternate
functions, and includes upsupported alternate functions as comments.

See the commnet block at the top of stm/pin_map.c for details on
how to use the pin mapper.

I also went ahead and modified stm/gpio.c to use the pin mapper.

4aee119f94 stm: Initialize sys.path with ["0:/", "0:/src", "0:/lib"]. 
This is compatible with what search path was before sys.path refactor,
with addition of module library path ("0:/lib").
