Previous to this patch the printing mechanism was a bit of a tangled
mess. This patch attempts to consolidate printing into one interface.
All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf. All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.
Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform. The former is only used when MICROPY_PY_IO is defined.
With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...). Code size is also reduced by around 200 bytes on
Thumb2 archs.
minimal: Allow to compile without defining MICROPY_HAL_H.2015-02-13T15:26:53+00:00Damien Georgedamien.p.george@gmail.com2015-02-13T15:26:53+00:00urn:sha1:601c814603801ad3af78e37d26c87a4470156738stmhal: Make pybstdio usable by other ports, and use it.2015-02-13T15:04:53+00:00Damien Georgedamien.p.george@gmail.com2015-02-13T15:04:53+00:00urn:sha1:0b32e50365b6e36474e183a7240ccfc8fa56830a
Now all ports can use pybstdio.c to provide sys.stdin/stdout/stderr, so
long as they implement mp_hal_stdin_* and mp_hal_stdout_* functions.

Found these by compiling stmhal with mp_uint_t of type uint32_t instead
of unsigned int. This actually makes a difference to the code, but just
a curiosity.
stmhal: Fix REPL printing by cooking output sent to stdout_obj.2014-07-20T12:57:43+00:00Damien Georgedamien.p.george@gmail.com2014-07-20T12:57:43+00:00urn:sha1:951ed9d02ffc826c68ee3af26c3530477e7e6156
Recent changes to builtin print meant that print was printing to the
mp_sys_stdout_obj, which was sending data raw to the USB CDC device.
The data should be cooked so that \n turns into \r\n.
