ed2b6ea0a8 stm32/i2c: Make timeout for hardware I2C configurable.
Previously the hardware I2C timeout was hard coded to 50ms which isn't
guaranteed to be enough depending on the clock stretching specs of the I2C
device(s) in use.

This patch ensures the hardware I2C implementation honors the existing
timeout argument passed to the machine.I2C constructor.  The default
timeout for software and hardware I2C is now 50ms.

b10d0664be extmod/machine_i2c: Add i2c.writevto() that can write a vector of bufs.
For example: i2c.writevto(addr, (buf1, buf2)).  This allows to efficiently
(wrt memory) write data composed of separate buffers, such as a command
followed by a large amount of data.

        uint16_t addr,
        size_t n,
        mp_machine_i2c_buf_t *bufs,

8bec0e869d docs/machine.I2C: Add writevto method to write a vector of byte bufs.
This allows to efficiently send to an I2C slave data that is made up of
more than one buffer.  Instead of needing to allocate temporary memory to
combine buffers together this new method allows to pass in a tuple or list
of buffers.  The name is based on the POSIX function writev() which has
similar intentions and signature.

The reasons for taking this approach (compared to having an interface with
separate start/write/stop methods) are:
- It's a backwards compatible extension.
- It's convenient for the user.
- It's efficient because there is only one Python call, then the C code can
  do everything in one go.
- It's efficient on the I2C bus because the implementation can do
  everything in one go without pauses between blocks of bytes.
- It should be possible to implement this extension in all ports, for
  hardware and software I2C.

Further discussion is found in issue #3482, PR #4020 and PR #4763.

e1e3704aa1 stm32/modmachine: Create dedicated asm function to branch to bootloader.
Recent gcc versions (at least 9.1) give a warning about using "sp" in the
clobber list.  Such code is removed by this patch.  A dedicated function is
instead used to set SP and branch to the bootloader so the code has full
control over what happens.

Fixes issue #4785.

0557f0b74b esp32/network_ppp: Add a timeout for closing PPP connection.
This also fixes deleting the PPP task, since eTaskGetState() never returns
eDeleted.

A limitation with this patch: once the PPP is deactivated (ppp.active(0))
it cannot be used again. A new PPP instance must be created instead.

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.

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.

  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.
