993ca572ca tools/upip.py: Add support for multiple index URLs with custom default.
The user can now select their own package index by either passing the "-i"
command line option, or setting the upip.index_urls variable (before doing
an install).

The https://micropython.org/pi package index hosts packages from
micropython-lib and will be searched first when installing a package.  If a
package is not found here then it will fallback to PyPI.

90fae9172a py/objarray: Add support for memoryview.itemsize attribute.
This allows figuring out the number of bytes in the memoryview object as
len(memview) * memview.itemsize.

The feature is enabled via MICROPY_PY_BUILTINS_MEMORYVIEW_ITEMSIZE and is
disabled by default.

3f54462add unix/modusocket: Fix use of setsockopt in usocket.settimeout impl.
The original code called setsockopt(SO_RCVTIMEO/SO_SNDTIMEO) with NULL
timeout structure argument, which is an illegal usage of that function.
The old code also didn't validate the return value of setsockopt, missing
the bug completely.

b8c74014e4 stm32/usbd_cdc_interface: Don't retransmit chars if USB is reconnected.
Before this change, if the USB was reconnected it was possible that some
characters in the TX buffer were retransmitted because tx_buf_ptr_out and
tx_buf_ptr_out_shadow were reset while tx_buf_ptr_in wasn't.  That
behaviour is fixed here by retaining the TX buffer state across reconnects.

Fixes issue #4761.

97753a1bbc stm32: Move factory reset files and code to separate source file.
The new function factory_reset_make_files() populates the given filesystem
with the default factory files.  It is defined with weak linkage so it can
be overridden by a board.

This commit also brings some minor user-facing changes:

- boot.py is now no longer created unconditionally if it doesn't exist, it
  is now only created when the filesystem is formatted and the other files
  are populated (so, before, if the user deleted boot.py it would be
  recreated at next boot; now it won't be).

- pybcdc.inf and README.txt are only created if the board has USB, because
  they only really make sense if the filesystem is exposed via USB.

34942d0a72 stm32/machine_uart: Change default UART timeout to 0, for non blocking.
It's more common to need non-blocking behaviour when reading from a UART,
rather than having a large timeout like 1000ms (the original behaviour).
With a large timeout it's 1) likely that the function will read forever if
characters keep trickling it; or 2) the function will unnecessarily wait
when characters come sporadically, eg at a REPL prompt.

089c9b71d1 py: remove "if (0)" and "if (false)" branches.
Prior to this commit, building the unix port with `DEBUG=1` and
`-finstrument-functions` the compilation would fail with an error like
"control reaches end of non-void function".  This change fixes this by
removing the problematic "if (0)" branches.  Not all branches affect
compilation, but they are all removed for consistency.

9a6f6fd68d nrf/boards: Add support for BLYST Nano module based boards.
- IBK-BLYST-NANO: Breakout board
- IDK-BLYST-NANO: DevKit board with builtin IDAP-M CMSIS-DAP Debug JTAG,
  RGB led
- BLUEIO-TAG-EVIM: Sensor tag board (environmental sensor
  (T, H, P, Air quality) + 9 axis motion sensor)

Also, the LED module has been updated to support individual base level
configuration of each LED. If set, this will be used instead of the
common configuration, MICROPY_HW_LED_PULLUP. The new configuration,
MICROPY_HW_LEDX_LEVEL, where X is the LED number can be used to set
the base level of the specific LED.

2a791170ce stm32/boards: Add NUCLEO_F413ZH board configuration.
The alternate function pin allocations are different to other NUCLEO-144
boards.  This is because the STM32F413 has a very high peripheral count:
10x UART, 5x SPI, 3x I2C, 3x CAN.  The pinout was chosen to expose all
these devices on separate pins except CAN3 which shares a pin with UART1
and SPI1 which shares pins with DAC.

34a7d7ebeb unix/gcollect: Make sure stack/regs get captured properly for GC.
When building with link time optimization enabled it is possible both
gc_collect() and gc_collect_regs_and_stack() get inlined into gc_alloc()
which can result in the regs variable being pushed on the stack earlier
than some of the registers. Depending on the calling convention, those
registers might however contain pointers to blocks which have just been
allocated in the caller of gc_alloc(). Then those pointers end up higher on
the stack than regs, aren't marked by gc_collect_root() and hence get
sweeped, even though they're still in use.

As reported in #4652 this happened for in 32-bit msvc release builds:
mp_lexer_new() does two consecutive allocations and the latter triggered a
gc_collect() which would sweep the memory of the first allocation again.

2459162599 lib/utils/interrupt_char: Invalidate interrupt char at start up.
Otherwise mp_interrupt_char will have a value of zero on start up (because
it's in the BSS) and a KeyboardInterrupt may be raised during start up.
For example this can occur if there is a UART attached to the REPL which
sends spurious null bytes when the device turns on.

7b5400134b tests/ussl_basic: Disable setblocking() calls.
Now that setblocking() is implemented in modussl_axtls, it calls into the
underlying stream object, and io.BytesIO doesn't have setblocking().

c76445315f extmod/modussl_axtls: Add non-blocking mode support.
It consists of:

1. "do_handhake" param (default True) to wrap_socket(). If it's False,
handshake won't be performed by wrap_socket(), as it would be done in
blocking way normally. Instead, SSL socket can be set to non-blocking mode,
and handshake would be performed before the first read/write request (by
just returning EAGAIN to these requests, while instead reading/writing/
processing handshake over the connection). Unfortunately, axTLS doesn't
really support non-blocking handshake correctly. So, while framework for
this is implemented on MicroPython's module side, in case of axTLS, it
won't work reliably.

2. Implementation of .setblocking() method. It must be called on SSL socket
for blocking vs non-blocking operation to be handled correctly (for
example, it's not enough to wrap non-blocking socket with wrap_socket()
call - resulting SSL socket won't be itself non-blocking).  Note that
.setblocking() propagates call to the underlying socket object, as
expected.

9c7c082396 extmod/modussl_mbedtls: Support non-blocking handshake.
For this, add wrap_socket(do_handshake=False) param. CPython doesn't have
such a param at a module's global function, and at SSLContext.wrap_socket()
it has do_handshake_on_connect param, but that uselessly long.

Beyond that, make write() handle not just MBEDTLS_ERR_SSL_WANT_WRITE, but
also MBEDTLS_ERR_SSL_WANT_READ, as during handshake, write call may be
actually preempted by need to read next handshake message from peer.
Likewise, for read(). And even after the initial negotiation, situations
like that may happen e.g. with renegotiation. Both
MBEDTLS_ERR_SSL_WANT_READ and MBEDTLS_ERR_SSL_WANT_WRITE are however mapped
to the same None return code. The idea is that if the same read()/write()
method is called repeatedly, the progress will be made step by step anyway.
The caveat is if user wants to add the underlying socket to uselect.poll().
To be reliable, in this case, the socket should be polled for both POLL_IN
and POLL_OUT, as we don't know the actual expected direction. But that's
actually problematic. Consider for example that write() ends with
MBEDTLS_ERR_SSL_WANT_READ, but gets converted to None. We put the
underlying socket on pull using POLL_IN|POLL_OUT but that probably returns
immediately with POLL_OUT, as underlyings socket is writable. We call the
same ussl write() again, which again results in MBEDTLS_ERR_SSL_WANT_READ,
etc. We thus go into busy-loop.

So, the handling in this patch is temporary and needs fixing. But exact way
to fix it is not clear. One way is to provide explicit function for
handshake (CPython has do_handshake()), and let *that* return distinct
codes like WANT_READ/WANT_WRITE. But as mentioned above, past the initial
handshake, such situation may happen again with at least renegotiation. So
apparently, the only robust solution is to return "out of bound" special
sentinels like WANT_READ/WANT_WRITE from read()/write() directly. CPython
throws exceptions for these, but those are expensive to adopt that way for
efficiency-conscious implementation like MicroPython.

fbd4e61e57 esp32/machine_wdt: Add timeout arg to select interval, make WDT panic.
The machine.WDT() now accepts the "timeout" keyword argument to select the
WDT interval.  And the WDT is changed to panic mode which means it will
reset the device if the interval expires (instead of just printing an error
message).

8031b7a25c stm32/powerctrl: Deselect PLLSAI as 48MHz src before turning off PLLSAI.
On the STM32F722 (at least, but STM32F767 is not affected) the CK48MSEL bit
must be deselected before PLLSAION is turned off, or else the 48MHz
peripherals (RNG, SDMMC, USB) may get stuck without a clock source.

In such "lock up" cases it seems that these peripherals are still being
clocked from the PLLSAI even though the CK48MSEL bit is turned off.  A hard
reset does not get them out of this stuck state.  Enabling the PLLSAI and
then disabling it does get them out.  A test case to see this is:

    import machine, pyb
    for i in range(100):
        machine.freq(122_000000)
        machine.freq(120_000000)
        print(i, [pyb.rng() for _ in range(4)])

On occasion the RNG will just return 0's, but will get fixed again on the
next loop (when PLLSAI is enabled by the change to a SYSCLK of 122MHz).

Fixes issue #4696.
