Damien George 7d86ac6c01 stm32: Add network driver for Wiznet5k using MACRAW mode and lwIP.
The Wiznet5k series of chips support a MACRAW mode which allows the host to
send and receive Ethernet frames directly.  This can be hooked into the
lwIP stack to provide a full "socket" implementation using this Wiznet
Ethernet device.  This patch adds support for this feature.

To enable the feature one must add the following to mpconfigboard.mk, or
mpconfigport.mk:

    MICROPY_PY_WIZNET5K = 5500

and the following to mpconfigboard.h, or mpconfigport.h:

    #define MICROPY_PY_LWIP (1)

After wiring up the module (X5=CS, X4=RST), usage on a pyboard is:

    import time, network
    nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4)
    nic.active(1)
    while not nic.isconnected():
        time.sleep_ms(50) # needed to poll the NIC
    print(nic.ifconfig())

Then use the socket module as usual.

Compared to using the built-in TCP/IP stack on the Wiznet module, some
performance is lost in MACRAW mode: with a lot of memory allocated to lwIP
buffers, lwIP gives Around 750,000 bytes/sec max TCP download, compared
with 1M/sec when using the TCP/IP stack on the Wiznet module.

Damien George 6b51eb22c8 stm32: Consolidate include of genhdr/pins.h to single location in pin.h.
genhdr/pins.h is an internal header file that defines all of the pin
objects and it's cleaner to have pin.h include it (where the struct's for
these objects are defined) rather than an explicit include by every user.

Damien George 8fa3d2996c stm32/modnwwiznet5k: Implement stream ioctl for the Wiznet driver.
Now supports polling for read and write ability.

Damien George 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.

Damien George 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.

Damien George 0a30ad96c8 stm32/modusocket: Return OSError(-2) if getaddrinfo fails.
This matches the behaviour of getaddrinfo in extmod/modlwip.c.

Li Weiwei 8c7db42ee3 stm32/modnwwiznet5k: Get the IP address of an established socket.
When wiznet5k_socket_accept is called, if a socket is established, get the
IP address of the socket.

Damien George 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.

Damien George 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.

Damien George 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.
