8c7db42ee3 stm32/modnwwiznet5k: Get the IP address of an established socket.

IP address of the socket.

a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.

d29b709642 stm32/timer: Enable ARPE so that timer freq can be changed smoothly.
The timer prescaler is buffered by default, and this patch enables ARPE
which buffers the auto-reload register.  With both of these registers
buffered it's now possible to smoothly change the timer's frequency and
have a smoothly varying PWM output.

347de3e218 stm32/usbdev: Change static function variable to non-static.
It's written straight away in the function on every call so it doesn't need
to be static.

d7cd1d2027 stm32/timer: Make pyb.Timer() instances persistent.
Prior to this patch calling pyb.Timer(id) would always create a new timer
instance, even if there was an existing one.  This patch fixes this
behaviour to match other peripherals, like UART, such that constructing a
timer with just the id will retrieve any existing instances.

The patch also refactors the way timers are validated on construction to
simplify and reduce code size.

da8c4c2653 py/builtinhelp: Change signature of help text var from pointer to array.
As a pointer (const char *) it takes up an extra word of storage which is

cc7fece309 stm32/modnwwiznet5k: Release the GIL on blocking network operations.
connect, send, recv, sendto and recvfrom now release the GIL.  accept
already releases the GIL because it calls mp_hal_delay_ms() within its
busy-wait loop.

19f1b39d6f stm32/i2c: When scanning for I2C devices only do 1 probe per address.
Previous to this patch the i2c.scan() method would do up to 100 probes per
I2C address, to detect the devices on the bus.  This repeated probing was a
relic from when the code was copied from the accelerometer initialisation,
which requires to do repeated probes while waiting for the accelerometer
chip to turn on.

But I2C devices shouldn't need more than 1 probe to detect their presence,
and the generic software I2C implementation uses 1 probe successfully.  So
this patch changes the implementation to use 1 probe per address, which
significantly speeds up the scan operation.

069fc48bf6 stm32/boards: Fix I2C1 pin mapping on NUCLEO_F401RE/F411RE boards.
This patch makes it consistent with the STM document describing the Arduino
layout.

Thanks to @shaoziyang for the original patch.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
