Quite natural to have d[int] = handle_int .

That's how CPython has it, in particular, "import __main__" should work.

Add the git version and build-date to the banner

Otherwise we have mixup between system and GC alloc.

Pointers are 2x bigger on 64 bit machines, so we should allocate twice
the memory to have a comparable heap size.

Str modulo

In addition to memory allocation failure, other problem was that 10**17
was overflowing.  Now passes.

Previous overflow test was inadequate.

A malloc/realloc fail now throws MemoryError.

Works on x86.

The alternate form for floating point doesn't work yet.
The %(name)s form doesn't work yet.

Home/end work in picocom and screen (different codes in those 2
programs).  Also, CTRL-A (for non-empty liny) and CTRL-E act as
home/end.

stmhal: Reimplement file support using stream protocol API.

To run the tests on the pyboard you need to set the "test_on_pyboard"
variable to "True", and also have tools/pyboard.py available for import
(easiest is to symlink to it).

Retested again on Ubuntu 12.04 armhf running in chroot on Samsung
ARM Chromebook (Cortex-A15).

This adds readline(), readall(), etc. methods. Also other fixes to make
Python API compliant and "with" support.

So far just includes "open" function, which should be supplied by a port.

TODO: Make the module #ifdef'ed.
