df952633ef windows: Add Appveyor CI builds for windows mingw port
Build and test 32bit and 64bit versions of the windows port using gcc
from mingw-w64. Note a bunch of tests which rely on floating point
math/printing have been disabled for now since they fail.

b184b6ae53 py/nlr: Fix nlr functions for 64bit ports built with gcc on Windows
The number of registers used should be 10, not 12, to match the assembly
code in nlrx64.c. With this change the 64bit mingw builds don't need to
use the setjmp implementation, and this fixes miscellaneous crashes and
assertion failures as reported in #1751 for instance.

To avoid mistakes in the future where something gcc-related for Windows
only gets fixed for one particular compiler/environment combination,
make use of a MICROPY_NLR_OS_WINDOWS macro.

To make sure everything nlr-related is now ok when built with gcc this
has been verified with:
- unix port built with gcc on Cygwin (i686-pc-cygwin-gcc and
  x86_64-pc-cygwin-gcc, version 6.4.0)
- windows port built with mingw-w64's gcc from Cygwin
 (i686-w64-mingw32-gcc and x86_64-w64-mingw32-gcc, version 6.4.0)
 and MSYS2 (like the ones on Cygwin but version 7.2.0)

8041de59fe windows/mpconfigport: Enable some features, including the Python stack
Add some features which are already enabled in the unix port and
default to using the Python stack for scoped allocations: this can be
more performant in cases the heap is heavily used because for example
the memory needed for storing *args and **kwargs doesn't require
scanning the heap to find a free block.

6fc58db5d8 windows/mpconfigport: Provide off_t definition for MSVC port
For MSVC off_t is defined in sys/types.h but according to the comment
earlier in mpconfigport.h this cannot be included directly.
So just make off_t the same as mp_off_t.
This fixes the build for MSVC with MICROPY_STREAMS_POSIX_API
enabled because stream.h uses off_t.

9bcdb0acd1 esp8266/Makefile: Remove commented-out unused lines.
These were copied from the stm32 port (then stmhal) at the very beginning
of this port, with the anticipation that the esp8266 port would have board
definition files with a list of valid pins and their names.  But that has
not been implemented and likely won't be, so remove the corresponding lines
from the Makefile.

c73360bfdb stm32: Allow to build a board without any hardware I2C ports defined.
This patch adds in internal config value MICROPY_HW_ENABLE_HW_I2C that is
automatically configured, and enabled only if one or more hardware I2C
ports are defined in the mpconfigboard.h file.  If none are defined then
the pyb.I2C class is excluded from the build, along with all supporting
code.  The machine.I2C class will still be available for software I2C.

Disabling all hardware I2C on an F4 board saves around 10,000 bytes of code
and 200 bytes of RAM.

badaf3ecfe esp8266/machine_hspi: After an SPI write wait for last byte to transfer.

ea6bddbf81 ports/qemu-arm: Rework "test" target using upytesthelper.
The way tinytest was used in qemu-arm test target is that it didn't test
much. MicroPython tests are based on matching the test output against
reference output, but qemu-arm's implementation didn't do that, it
effectively tested just that there was no exception during test
execution. "upytesthelper" wrapper was introduce to fix it, so switch
test implementation to use it.

This requires passing different CFLAGS when building the firmware, so
split out test-related parts to Makefile.test.

78302f7bb2 esp32/modesp: Add osdebug() function to disable or change IDF logging.
Code lineage:
osdebug() is based loosely on the version in esp8266, but there didn't
seem to be an obvious way of choosing a particular UART. The basic
behavior is the same, though: provide None, and logging is disabled;
provide an integer and logging is restored to the default level.

To build on that, and because the IDF provides more functionality, a
second parameter has now been implemented which allows the active log
level to be set:

   esp.osdebug(uart[, level])

The module has a corresponding set of LOG_ values to set this accordingly.

b0853b5a39 esp32/modnetwork.c: Fix for setting DNS with network.WLAN.ifconfig().

API to ensure it is thread safe.

bc08c884a2 esp32: Add new port to Espressif ESP32 SoC.
This commit is a combination of 216 commits from the initial stages of
development of this port, up to and including the point where the code was
moved to the ports/esp32 directory.  These commits were mostly concerned
with setting up the build system and getting a reliable port working with
basic features.  The following is a digest of the original commits in their
original order (most recent listed first), grouped where possible per
author.  The list is here to give credit for the work and provide some
level of traceability and accountability.  For the full history of
development please consult the original repository.

  Code lineage (as seen by previous commits): I copied the ESP8266 code,

  edited.  Total derivative work.

Andy Valencia <vandyswa@gmail.com>
  esp32: Add PWM support via machine.PWM class.

  Code lineage:
  I started by copying the esp8266 machine_pwm.c. I used information from the
  ESP32 Technical Reference Manual, the esp-idf documentation, and the SDK's
  sample ledc example code (but I did not copy that code, just studied it to
  understand the SDK's API for PWM). So aside from the code copied from the
  esp8266 PWM support, everything else you see is just new code I wrote.

  I wasn't an employee of anybody when I wrote it, and I wrote it with the
  understanding and intention that it's simply a derivative work of the
  existing micropython code. I freely and willingly contribute it to the
  project and intend that it not change the legal status of the micropython
  code base in any way, even if it is included in that base in whole or part.

e7fc765880 unix/mpconfigport: Disable uio.resource_stream().
This function was implemented as an experiment, and was enabled only in
unix port. To remind, it allows to access arbitrary files frozen as
source modules (vs bytecode).

However, further experimentation showed that the same functionality can
be implemented with frozen bytecode. The process requires more steps, but
with suitable toolset it doesn't matter patch. This process is:

1. Convert binary files into "Python resource module" with
tools/mpy_bin2res.py.
2. Freeze as the bytecode.
3. Use micropython-lib's pkg_resources.resource_stream() to access it.

In other words, the extra step is using tools/mpy_bin2res.py (because
there would be wrapper for uio.resource_stream() anyway).

Going frozen bytecode route allows more flexibility, and same/additional
efficiency:

1. Frozen source support can be disabled altogether for additional code
savings.
2. Resources could be also accessed as a buffer, not just as a stream.

There're few caveats too:

1. It wasn't actually profiled the overhead of storing a resource in
"Python resource module" vs storing it directly, but it's assumed that
overhead is small.
2. The "efficiency" claim above applies to the case when resource
file is frozen as the bytecode. If it's not, it actually will take a
lot of RAM on loading. But in this case, the resource file should not
be used (i.e. generated) in the first place, and micropython-lib's
pkg_resources.resource_stream() implementation has the appropriate
fallback to read the raw files instead. This still poses some distribution
issues, e.g. to deployable to baremetal ports (which almost certainly
would require freezeing as the bytecode), a distribution package should
include the resource module. But for non-freezing deployment, presense
of resource module will lead to memory inefficiency.

All the discussion above reminds why uio.resource_stream() was implemented
in the first place - to address some of the issues above. However, since
then, frozen bytecode approach seems to prevail, so, while there're still
some issues to address with it, this change is being made.

This change saves 488 bytes for the unix x86_64 port.
