5b7fd20fea Add support for storing args during an exception raised by an irq. 
The user code should call micropython.alloc_emergency_exception_buf(size)
where size is the size of the buffer used to print the argument
passed to the exception.

With the test code from #732, and a call to
micropython.alloc_emergenncy_exception_buf(100) the following error is
now printed:
```python
>>> import heartbeat_irq
Uncaught exception in Timer(4) interrupt handler
Traceback (most recent call last):
  File "0://heartbeat_irq.py", line 14, in heartbeat_cb
NameError: name 'led' is not defined
```

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

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.
