d6bf3658f4 stm32: Make uos.dupterm() conform to specs by using extmod version.
The legacy function pyb.repl_uart() is still provided and retains its
original behaviour (it only accepts a UART object).  uos.dupterm() will now
accept any object with write/readinto methods.  At the moment there is just
1 dupterm slot.

0eb333e3cf stm32/mphalport: Improve efficiency of mp_hal_stdout_tx_strn_cooked.
Also simplifies the code by removing the specialised (and inefficient)
cooked functions from UART and USB_VCP.

285ac58532 stm32/modnwwiznet5k: Increase SPI bus speed to 42MHz.
The W5200 and W5500 can support up to 80MHz so 42MHz (the maximum the
pyboard can do in its standard configuration) should be safe.

Tested to give around 1050000 kbytes/sec TCP download speed on a W5500,
which is about 10% more than with the previous SPI speed of 21MHz.

e36821a766 stm32/modnwwiznet5k: Add support for W5500 Ethernet chip.
Which Wiznet chip to use is a compile-time option: MICROPY_PY_WIZNET5K
should be set to either 5200 or 5500 to support either one of these
Ethernet chips.  The driver is called network.WIZNET5K in both cases.

Note that this commit introduces a breaking-change at the build level
because previously the valid values for MICROPY_PY_WIZNET5K were 0 and 1
but now they are 0, 5200 and 5500.

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.

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.

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.
