645582fe14 py: Make id() return small int for the most common address space mapping. 
Many OSes/CPUs have affinity to put "user" data into lower half of address
space. Take advantage of that and remap such addresses into full small int
range (including negative part).

If address is from upper half, long int will be used. Previously, small
int was returned for lower quarter of address space, and upper quarter. For
2 middle quarters, long int was used, which is clearly worse schedule than
the above.

1d8816c36b Deal with reading a buffer less than what was allocated. 
With this fix, file_long_read now passes.

cb66f41ebc py: Make print() accept "file" argument, and actually print to stream. 
And not system printf(), like it was before. For this, move pfenv_printf()
from stmhal port to py/.

1694bc733d py: Add stream reading of n unicode chars; unicode support by default. 
With unicode enabled, this patch allows reading a fixed number of
characters from text-mode streams; eg file.read(5) will read 5 unicode
chars, which can made of more than 5 bytes.

For an ASCII stream (ie no chars > 127) it only needs to do 1 read.  If
there are lots of non-ASCII chars in a stream, then it needs multiple
reads of the underlying object.

Adds a new test for this case.  Enables unicode support by default on
unix and stmhal ports.

58c9586c34 emitbc: Fix structure field alignment issue. 
dummy_data field is accessed as uint value (e.g.
in emit_write_bytecode_byte_ptr), but is not aligned as such, which causes
bus errors or incorrect behavior on any arch requiring strictly aligned
data (ARM pre-v7, MIPS, etc, etc).

Conflicts:
	stmhal/pin_named_pins.c
	stmhal/readline.c

Renamed HAL_H to MICROPY_HAL_H.  Made stmhal/mphal.h which intends to
define the generic Micro Python HAL, which in stmhal sits above the ST
HAL.

b601d9574a py: Improvements to native emitter. 
Native emitter can now compile try/except blocks using nlr_push/nlr_pop.
It probably only works for 1 level of exception handling.  It doesn't
work on Thumb (only x64).

Native emitter can also handle some additional op codes.

With this patch, 198 tests now pass using "-X emit=native" option to
micropython.

ec6fa8732b windows: Sync mpconfigport.h with the unix' version 
- rearrange/add definitions that were not there so it's easier to compare both
- use MICROPY_PY_SYS_PLATFORM in main.c since it's available anyway
- define EWOULDBLOCK, it is missing from ingw32
