They are much slower than NIST (SECP) curves and shouldn't be needed.

Curve25519 arithmetic is supported in mbedtls, but it's not used for TLS.
So there's no need to have this option enabled.

This is necessary to access sites that only support these protocols.
The rp2 port already has ECDH enabled, so this just adds ECDSA there. The
other ports now gain both ECDH and ECDSA. The code size increase is:
- rp2 (PICO_W): +2916 bytes flash, +24 bytes BSS
- stm32 (PYBD_SF6): +20480 bytes flash, +32 bytes data, +48 bytes BSS
- mimxrt (TEENSY41): +20708 bytes flash, +32 bytes data, +48 bytes BSS
- unix (standard x86-64): +39344 executable, +1744 bytes data, +96 BSS
This is obviously a large increase in code size. But there doesn't seem to
be any other option because without elliptic curve cryptography devices are
partially cut off from the internet. For use cases that require small
firmware size, they'll need to build custom firmware with a custom mbedtls
config.

The following multi-tests pass (eg with PYBD_SF6+LEGO_HUB_NO6):
ble_gap_advertise.py
ble_gap_connect.py
ble_gap_device_name.py
ble_gattc_discover_services.py
ble_gatt_data_transfer.py
perf_gatt_char_write.py
perf_gatt_notify.py
stress_log_filesystem.py
These are the same tests that passed prior to this BTstack update.
Also tested on the unix port using H4 transport.

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.

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.

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.

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).

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.

It now prints lines like:
Pin("D9", mode=IN, pull=PULL_UP, GPIO=PA07)
or
LED("LED")
showing for consistency the names as given in pins.csv. For pins, the GPIO
numer is printed as well for a reference.
Porting PR #8040 by @hoihu to SAMD, following the commit
5873390226.
One small addition: before executing keyboard interrupt, the input buffer
is cleared.
Changes are:
- The pin-af-table-SAMDxx.csv file are moved to the mcu directories with
the name as pin-af-table.csv.
- The handling in Makefile and pin_af.c is simplified.
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.
