bool(None) has a fast path in mp_obj_is_true so doesn't need to be
handled in none_unary_op. The only caveat is that subclassing may
bypass the mp_obj_is_true function, but actually you aren't allowed to
subclass classes that have singleton instances like NoneType (see
https://mail.python.org/pipermail/python-dev/2002-March/020822.html for
reference on this point).
This is actually long overdue: the README in the windows directory has been
updated once to indicate mingw32 is abandoned and not ok to use with uPy,
but we forgot travis builds were still using it.
As a bonus the travis build will succeed again since moduerrno.c now compiles.

py/makeqstrdefs.py declares that it works with python 2.6 however the
syntax used to initialise of a set with values was only added in python
2.7. This leads to build failures when the host system doesn't have
python 2.7 or newer.
Instead of using the new syntax pass a list of initial values through
set() to achieve the same result. This should work for python versions
from at least 2.6 onwards.

If a user tries to call `swint()` while interrupt is disabled the flag in
SWIER is set but the interrupt is not triggered and therefore the SWIER bit
is not cleared. When the interrupt is again enabled the next call to
`swint()` won't trigger the IRQ because a 0 to 1 transition will not occur.
The LCD interface library fails to deassert the chip select of the LCD
after an SPI transmission. Consequently using the SPI with other
peripherals disturbs the state of the LCD. This patch changes
lcd.lcd_out() to deassert CS after each transmission to the LCD.
Tested on a STM32F7DISCO at 216MHz. All tests generating code (inlineasm,
native, viper) now pass, except pybnative/while.py, but that's because
there is no LED(2).
machine.POWER_ON is renamed to machine.PWRON_RESET to match other
reset-cause constants that all end in _RESET. The cc3200 port keeps a
legacy definition of POWER_ON for backwards compatibility.
