ab317a0d66 py/misc: Remove use of bitfield from vstr_t.
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.

d6d8722558 extmod: Make extmod.mk self-contained.
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.

87011f6353 extmod/extmod.mk: Make extmod.mk handle GIT_SUBMODULES.
This applies to nimble, btstack, axtls, mbedtls, lwip.

Rather than having the ports individually manage GIT_SUBMODULES for these
components, make extmod.mk append them when the relevant feature is
enabled.

065af04a4e unix/Makefile: Don't use _MOD variable names.
This conflicts with the triple-usage of these variables for user-C-modules
and extmod source.

For CFLAGS_MOD, just use CFLAGS directly. For SRC, use SRC_C directly as
the relevant files are all guarded by the preprocessor anyway.

3cc6decfc4 py/py.mk: Make user-C-module handling self-contained in py.mk.
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).

b8982ec5f9 tools/verifygitlog.py: Add additional help for subject line issues.
This check used to just show the regular expression that failed to match,
but the rules are pretty subtle and hard to interpret from the regular
expression alone.

Add some basic checks for the main things that go wrong:
 - Missing capitalisation.
 - Missing full-stop.
 - Missing path.
 - Single-word subject.

20e7313453 samd/clock_config: Add HW_DFLL_USB_SYNC and HW_MCU_OSC32KULP extensions.
Two new compile flags are:

MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the
crystal.  It will synchronize the DFLL48M clock with the USB's SOF pulse.
If no USB is connected, it will fall back to open loop mode.  The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.

MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source.  Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal.  This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash.  Drawback: ticks_ms() and time.time() vs. than
ticks_us() and the peripherals like PWM run at not synchronous clocks.

a415752173 samd/machine_bitstream: Add the machine.bitstream() function.
The SAMD21 implementation is an adaption of @jimmo's code for STM32Lxx.
The only changes are the addresses and names of the port registers and the
timing parameters.

SAMD21: The precision is about +/-25ns at 48MHz clock frequency.  The first
two cycles are about 40-60 ns longer than set.  But still good enough to
drive a neopixel device.

SAMD51: The precision is about +/-30ns at 120MHz clock frequency.  Good
enough to drive a neopixel device.
