Borrowing an idea from the mimxrt port (also stm32 port): in the loader
input file memmap_mp.ld calculate __GcHeapStart and __GcHeapEnd as the
unused RAM. Then in main.c use these addresses as arguments to gc_init().
The benefits of this change are:
1) When libraries are added or removed in the future changing BSS usage,
main.c's sizing of the GC heap does not need to be changed.
2) Currently these changes make the GC area about 30 KBytes larger, eg on
PICO_W the GC heap increases from 166016 to 192448 bytes. Without that
change this RAM would never get used.
3) If someone wants to disable one or more SRAM blocks on the RP2040 to
reduce power consumption it will be easy: just change the MEMORY section
in memmap_mp.ld. For instance to not use SRAM2 and SRAM3 change it to:
MEMORY
{
FLASH(rx) : ORIGIN = 0x10000000, LENGTH = 2048k
RAM(rwx) : ORIGIN = 0x21000000, LENGTH = 128k
SCRATCH_X(rwx) : ORIGIN = 0x20040000, LENGTH = 4k
SCRATCH_Y(rwx) : ORIGIN = 0x20041000, LENGTH = 4k
}
Then to turn off clocks for SRAM2 and SRAM3 from MicroPython, set the
appropriate bits in WAKE_EN0 and SLEEP_EN0.
Tested by running the firmware.uf2 file on PICO_W and displaying
micropython.mem_info(). Confirmed GC total size approximately matched the
size calculated by the loader.

This function seems to work fine in multi-core applications now.
The delay is now in units of microseconds instead of depending on the clock
speed, and is adjustable by board configuration headers.
Also added documentation.
The device-under-test should use `multitest.expect_reboot()` to indicate
that it will reboot.

This brings in the following new modules: hs3003, bmi270, bmm150, cbor2
and senml. It also refactors lsm6dsox and lsm9ds1.

These changes allow the firmware to support both the REV-1 and REV-2
versions of the board:
- Freeze the new device drivers used in REV-2.
- Add a board-level module that abstracts the IMU chipset.
Changes are:
- Freeze micropython-lib time module to get strftime.
- Reserve the last 1MB of QSPI flash for (optional) WiFi firmware storage.
- Disable SD card mount on boot.
- Enable high-speed BLE firmware download.
This is handy when you are doing builds outside of the Git repository but
still want to record that information.

This is for boards without networking support so that the default boot.py
continues to work.
Also update boot.py to use network.country and network.hostname instead.

This removes the previous WiFi driver from drivers/cyw43 (but leaves behind
the BT driver), and makes the stm32 port (i.e. PYBD and Portenta) use the
new "lib/cyw43-driver" open-source driver already in use by the rp2 port.

Rather than duplicating the implementation of `network`, this allows
ESP8266 to use the shared one in extmod. In particular this gains access
to network.hostname and network.country.
Other than adding these two methods, there is no other user-visible change.

This allows for a port (e.g. esp8266/esp32) to use extmod/modnetwork.c
and provide the globals dict, rather than just a list of interfaces.
When this is used, the default implementation of `network.route` and the
NIC list is not enabled.
Also splits out the LWIP-specific helpers from modnetwork.c into
network_lwip.c.

This provides a standard interface to setting the global networking config
for all interfaces and interface types.
For ports that already use either a static hostname (mimxrt, rp2) they will
now use the configured value. The default is configured by the port
(or optionally the board).
For interfaces that previously supported .config(hostname), this is still
supported but now implemented using the global network.hostname.
Similarly, pyb.country and rp2.country are now deprecated, but the methods
still exist (and forward to network.hostname).
Because ESP32/ESP8266 do not use extmod/modnetwork.c they are not affected
by this commit.

Without this it's possible to get a compiler error about the comparison
always being true, because MP_BINARY_OP_LESS is 0. And it seems that gcc
optimises these 6 equality comparisons into the same size machine code as
before.
Prior to this fix, pow(1.5, inf) and pow(0.5, -inf) (among other things)
would incorrectly raise a ValueError, because the result is inf with the
first argument being finite. This commit fixes this by allowing the result
to be infinite if the first or second (or both) argument is infinite.
This fix doesn't affect the other three math functions that have two
arguments:
- atan2 never returns inf, so always fails isinf(ans)
- copysign returns inf only if the first argument x is inf, so will never
reach the isinf(y) check
- fmod never returns inf, so always fails isinf(ans)

Currently, certain mpremote filesystem operations can fail on Windows due
to a mixing of '/' and '\' for path separators. Eg if filesystem_command()
is called with a destination that ends in / then dest.endswith(os.path.sep)
will return False, which gives the wrong behaviour (it does end in a path
separator).
For similar reasons to 7e9a15966a, it's best
to use '/' everywhere in pyboard.py and mpremote, because the target device
understands only '/'. mpremote already does this, so the remaining place
to fix it is in pyboard.y, to convert all incoming paths to use '/' instead
of '\'.
This effectively reverts 57fd66b80f which
tried to fix the problem in a different way.
