65cad12d38 py: Add option to compiler to specify default code emitter. 
Also add command line option to unix port to select emitter.

27e735fd18 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/.

8b0535e23f py: Change module globals from mp_map_t* to mp_obj_dict_t*. 
Towards addressing issue #424.

Had a small increase to ROM usage (order 60 bytes).

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

TODO: Make the module #ifdef'ed.

df6567e634 Merge map.h into obj.h. 
Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation.  Thus, the definitions
are now in obj.h instead.  map.h is removed.

d17926db71 Rename rt_* to mp_*. 
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

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.

caac542b23 Proper support for registering builtin modules in ROM.

are now named mod*.[ch].

849a0dda86 stm: Add some floating-point math functions. 
These have been taken from the musl library.  It's a bit of a hack for

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).
