stmhal: Add ADC function to read data at a given frequency.
Reads ADC values into a bytearray (or similar) at a fixed rate. Needs a
better name and improved API. Also fix up DAC dma function (which also
needs a better name and API).

stmhal: Add stm module, which contains some constants for the MCU.
Also contains raw memory read/write functions, read8, read16, read32,
write8, write16, write32. Can now do:
stm.write16(stm.GPIOA + stm.GPIO_BSRRL, 1 << 13)
This turns on the red LED.
With the new constant folding, the above constants for the GPIO address
are actually compiled to constants (and the addition done) at compile
time. For viper code and inline assembler, this optimisation will make
a big difference. In the inline assembler, using these constants would
not be possible without this constant folding.

is transferred to nlr_jump_fail (which should bail out with a fatal
error).

Improve REPL detecting when input needs to continue.
Full CPython compatibility with this requires actually parsing the
input so far collected, and if it fails parsing due to lack of tokens,
then continue collecting input. It's not worth doing it this way. Not
having compatibility at this level does not hurt the goals of Micro
Python.

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/.

py: Make globals and locals proper dictionary objects.
Finishes addressing issue #424 .
In the end this was a very neat refactor that now makes things a lot
more consistent across the py code base. It allowed some
simplifications in certain places, now that everything is a dict object.
Also converted builtins tables to dictionaries. This will be useful
when we need to turn builtins into a proper module.
