robert-hh 76cf98c35b samd/mcu: Implement a hardware seed for the SAMD21 random module.
By using the phase jitter between the DFLL48M clock and the FDPLL96M clock.
Even if both use the same reference source, they have a different jitter.
SysTick is driven by FDPLL96M, the us counter by DFLL48M.  As a random
source, the us counter is read out on every SysTick and the value is used
to accumulate a simple multiply, add and xor register.  According to tests
it creates about 30 bit random bit-flips per second.  That mechanism will
pass quite a few RNG tests, has a suitable frequency distribution and
serves better than just the time after boot to seed the PRNG.

Stig Bjørlykke 209a6bb6b7 docs/rp2: Make LED have exactly 50% duty cycle in PIO 1Hz example.
This ensures the same number of cycles are used for LED on and LED off in
the PIO 1Hz example.  It's also possible to swap the first set() and the
irq() to avoid using an extra instruction, but this tutorial is a good
example of how to calculate the cycles.

Damien George 2283b6d68f py: Pass in address to compiled module instead of returning it.
This change makes it so the compiler and persistent code loader take a
mp_compiled_module_t* as their last argument, instead of returning this
struct.  This eliminates a duplicate context variable for all callers of
these functions (because the context is now stored in the
mp_compiled_module_t by the caller), and also eliminates any confusion
about which context to use after the mp_compile_to_raw_code or
mp_raw_code_load function returns (because there is now only one context,
that stored in mp_compiled_module_t.context).

Reduces code size by 16 bytes on ARM Cortex-based ports.

Michael Mogenson 921f397acb tools/mpremote: Only auto connect to serial device with USB VID/PID.
On MacOS and Windows there are a few default serial devices that are
returned by `serial.tools.list_ports.comports()`. For example on MacOS:

```
{'description': 'n/a',
 'device': '/dev/cu.Bluetooth-Incoming-Port',
 'hwid': 'n/a',
 'interface': None,
 'location': None,
 'manufacturer': None,
 'name': 'cu.Bluetooth-Incoming-Port',
 'pid': None,
 'product': None,
 'serial_number': None,
 'vid': None}

{'description': 'n/a',
 'device': '/dev/cu.wlan-debug',
 'hwid': 'n/a',
 'interface': None,
 'location': None,
 'manufacturer': None,
 'name': 'cu.wlan-debug',
 'pid': None,
 'product': None,
 'serial_number': None,
 'vid': None}
```

Users of mpremote most likely do not want to connect to these ports. It
would be desirable if mpremote did not select this ports when using the
auto connect behavior. These serial ports do not have USB VID or PID
values and serial ports for Micropython boards with FTDI/serial-to-USB
adapter or native USB CDC/ACM support do.

Check for the presence of a USB VID / PID int value when selecting a
serial port to auto connect to. All serial ports will still be listed by
the `list` command and can still be selected by name when connecting.

Jim Mussared d94141e147 py/persistentcode: Introduce .mpy sub-version.
The intent is to allow us to make breaking changes to the native ABI (e.g.
changes to dynruntime.h) without needing the bytecode version to increment.

With this commit the two bits previously used for the feature flags (but
now unused as of .mpy version 6) encode a sub-version.  A bytecode-only
.mpy file can be loaded as long as MPY_VERSION matches, but a native .mpy
(i.e. one with an arch set) must also match MPY_SUB_VERSION.  This allows 3
additional updates to the native ABI per bytecode revision.

The sub-version is set to 1 because the previous commits that changed the
layout of mp_obj_type_t have changed the native ABI.

Jim Mussared cacc96d98c extmod/modbluetooth: Replace def_handle with end_handle in char IRQ.
This is technically a breaking change, but:
a) We need the end handle to do descriptor discovery properly.
b) We have no possible use for the existing definition handle in the
characteristic result IRQ. None of the methods can use it, and therefore
no existing code should be using it in a way that changing it to a
different integer value should break.

Unfortunately NimBLE doesn't make it easy to get the end handle, so also
implement a mechanism to use the following characteristic to calculate
the previous characteristic's end handle.
