Vicente Olivert Riera 587914169c unix/modffi.c: cast first to intptr_t when casting from/to pointer
This fixes errors like these ones:

modffi.c: In function 'return_ffi_value':
modffi.c:143:29: error: cast to pointer from integer of different size
[-Werror=int-to-pointer-cast]
             const char *s = (const char *)val;
                             ^
modffi.c:162:20: error: cast to pointer from integer of different size
[-Werror=int-to-pointer-cast]
             return (mp_obj_t)val;
                    ^
modffi.c: In function 'ffifunc_call':
modffi.c:358:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
             values[i] = (ffi_arg)a;
                         ^
modffi.c:373:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
             values[i] = (ffi_arg)s;
                         ^
modffi.c:381:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
             values[i] = (ffi_arg)bufinfo.buf;
                         ^
modffi.c:384:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
             values[i] = (ffi_arg)p->func;
                         ^

These errors can be highlighted when building micropython from MIPS64
n32 because ffi_arg is 64-bit wide and the pointers on MIPS64 n32 are
32-bit wide, so it's trying to case an integer to a pointer (or
vice-versa) of a different size. We should cast first the pointer (or the
integer) to a pointer sized integer (intptr_t) to fix that problem.

Paul Sokolovsky 696eee9475 modffi: dlsym() doesn't set errno, so use ENOENT for OSError.
This may be a bit confusing, as ENOENT is often rendered as "No such
file or directory", but any other code would be only more confusing.

Damien George a9afcb159a unix/modffi.c: get_buffer is allowed to return NULL if len=0.
This is consistent with the logic in mp_get_buffer, and the code here is
an inlined version of that function.

Damien George 7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism.
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.

Damien George be6d8be91e py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack.
mp_obj_int_get_truncated is used as a "fast path" int accessor that
doesn't check for overflow and returns the int truncated to the machine
word size, ie mp_int_t.

Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word
sized values.

Addresses issues #779 and #998.

same.

Damien George 17598d49e1 unix: Don't use -Wno-error=cpp or #warning; fix strict alias warning.
For the sake of older versions of gcc (and other compilers), don't use
the #warning CPP directive, nor the -Wno-error=cpp option.

Also, fix a strict alias warning in modffi.c for older compilers, and
add a test for ffi module.

Addresses issue #847.

Damien George 2617eebf2f Change const byte* to const char* where sensible.
This removes need for some casts (at least, more than it adds need
for new casts!).

Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.
