The conversion of characters like _space_ in qstrs is a bit
ad-hoc. Because "_not_" stands for the logical negation character ¬
the recently added message was displayed incorrectly:
```
>>> socket.getaddrinfo('does.not.exist', 0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
gaierror: (-2, 'Name or service_space¬space_known')
```
I had noticed this, but evidently failed to include the fix in
the problem in #7269.
MP_REGISTER_MODULE would use identifiers like
"MODULE_DEF_MP_QSTR___FUTURE__" which would in turn cause
a QSTR to be generated for it. This wasn't desirable, because the
qstr would never be used.
This clears out quite a bit of flash storage on the proxlight trinkey.
The code was already checking for duplicate kwargs for named parameters but
if `**kwargs` was given as a parameter, it did not check for multiples of
the same argument name.
This fixes the issue by adding an addition test to catch duplicates and
adds a test to exercise the code.
Fixes issue #10083.

Implements dictionary union according to PEP 584's specifications, minus
the fact that dictionary entries are not guaranteed to be in insertion
order. This feature is enabled with MICROPY_CPYTHON_COMPAT.

If a CMake-build is run with `make BUILD=/outside/path` then
makeversionheader.py is run with the CWD set to the build directory, which
means the git version lookup will fail and silently fall back to the
mpconfig.h mode (giving the wrong result).
This commit:
- Uses the location of makeversionheader.py to find the repo path.
- Allows overriding this path via --repo-path.

This can be tested using ports/minimal and qemu:
make CC=mips-linux-gnu-gcc-8
Then run with qemu-mips:
stty raw opost -echo;
QEMU_LD_PREFIX=/usr/mips-linux-gnu/ qemu-mips build/firmware.elf;
sleep 1; reset

This adds the __cause__, __context__ and __suppress_context__
members to exception objects and makes e.g., `raise exc from cause`
set them in the same way as standard Python.
.. a fast helper for animations. It is similar to and inspired by the
PixelMap helper in Adafruit LED Animation library, but with an extremely
fast 'paste' method for setting a series of pixels. This is a common
operation for many animations, and can give a substantial speed improvement.
It's named `adafruit_pixelmap` so that we can package a compatible version
in pure Python for systems that can't fit it in C in flash, or for
Blinka.
This is a proof of concept and can make a very fast comet animation:
```python
import time
import adafruit_pixelbuf
import adafruti_pixelmap
import board
import neopixel
from supervisor import ticks_ms
from adafruit_led_animation.animation.solid import Solid
from adafruit_led_animation import color
pixel_pin = board.GP0
pixel_num = 96
pixels = neopixel.NeoPixel(pixel_pin, pixel_num, brightness=1, auto_write=False, pixel_order="RGB")
evens = adafruit_pixelmap.PixelMap(pixels, tuple(range(0, pixel_num, 2)))
odd_indices = tuple((i, i+2) for i in range(1, pixel_num, 4))
print(odd_indices)
odds = adafruit_pixelbuf.PixelMap(pixels, odd_indices)
assert len(odds) == len(odd_indices)
comet_length = 16
comet1 = [color.calculate_intensity(color.GREEN, ((1+i) / comet_length) ** 2.4)
for i in range(comet_length)]
comet2 = [color.calculate_intensity(color.PURPLE, ((1+i) / comet_length) ** 2.4)
for i in range(comet_length)]
pos1 = 0
pos2 = 96//4
while True:
evens.paste(comet1, pos1, wrap=True, reverse=False, others=0)
pos1 = (pos1 + 1) % len(evens)
odds.paste(comet2, pos2, wrap=True, reverse=True, others=0)
pos2 = (pos2 - 1) % len(odds)
pixels.show()
m = ticks_ms()
if m % 2000 > 1000:
time.sleep(.02)
```
This prevents a very subtle bug caused by writing e.g. `bytearray('\xfd')`
which gives you `(0xc3, 0xbd)`.

There are two calls to mp_builtin___import__():
1. ports/unix/main.c:main_() which provides a str in args[0]
2. py/runtime.c:mp_import_name() which provides a qstr in args[0]
The default implementation of mp_builtin___import__() is
mp_builtin___import___default() which has a different implementation based
on MICROPY_ENABLE_EXTERNAL_IMPORT.
If MICROPY_ENABLE_EXTERNAL_IMPORT is disabled then the handling of weak
links assumes that args[0] is a `const char *`, when it is either a str or
qstr object.
Use the existing qstr of the module name instead, and also use a vstr
instead of strcpy() to ensure no overflow occurs.
Commit 64af916c111b61bce82c00f356a6b1cb81946d87 removed the version string
from docs/conf.py. py/mpconfig.h is a better place to get the version
from, so use that (when there is no git repository).

In order for v1.19.1 to load a .mpy, the formerly-feature-flags which are
now used for the sub-version must be zero.
The sub-version is only used to indicate a native version change, so it
should be zero when emitting bytecode-only .mpy files.

We adopted the file "py/ioctl.h" and the ioctl names beginning
with MP_IOCTL_POLL while micropython went with "py/stream.h" and
MP_STREAM_POLL.
Align with upstream.
Closes#6711
Since there is only one flag, we don't need to use a bitfield in vstr_t.
Compilers emit extra instructions to access a bitfield, so this should
reduce the binary size a small amount.

This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.
Make all extmod variables (src, flags, etc) private to extmod.mk.
Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.
Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

Removes the need for the port to add anything to OBJS or SRC_QSTR.
Also makes it possible for user-C-modules to differentiate between code
that should be processed for QSTR vs other files (e.g. helpers and
libraries).
