1c6d91d968 extmod/modlwip: Add print_pcbs() debug function. 
This requires lwIP built with LWIP_DEBUG (or it will be no-op).

7a012f4793 extmod/modlwip: Protect recv/accept Python callback against exceptions. 
Using usual call_function_*_protected() helper, to avoid NLR jump crashes.

7d57037906 extmod/modlwip: Add ability to run callback on "recv" and "accept" events. 
To use: .setsockopt(SOL_SOCKET, 20, lambda sock: print(sock)). There's a
single underlying callback slot. For normal sockets, it serves as data
received callback, for listening sockets - connection arrived callback.

7063210014 extmod/modlwip: Fix for loss of data in unaccepted incoming sockets. 
When lwIP creates a incoming connection socket of a listen socket, it
sets its recv callback to one which discards incoming data. We set
proper callback only in accept() call, when we allocate Python-level
socket where we can queue incoming data. So, in lwIP accept callback
be sure to set recv callback to one which tells lwIP to not discard
incoming data.

Between 1.4.0 and 1.4.1, lwIP errors were renumbered.

de0c84ebf1 extmod/modlwip: lwip_tcp_send: Handle properly send buffer full condition. 
Per POSIX http://pubs.opengroup.org/onlinepubs/9699919799/functions/send.html :
"If space is not available at the sending socket to hold the message to be
transmitted, and the socket file descriptor does not have O_NONBLOCK set,
send() shall block until space is available. If space is not available at the
sending socket to hold the message to be transmitted, and the socket file
descriptor does have O_NONBLOCK set, send() shall fail [with EAGAIN]."

09ed5bcbbb extmod/modlwip: Rework getaddrinfo() data passing. 
The code is based on Damien George's implementation for esp8266 port,
avoids use of global variables and associated re-entrancy issues, and
fixes returning stale data in some cases.

e5b047369b extmod/modlwip: Use MICROPY_EVENT_POLL_HOOK for event polling if defined. 
Instead of just delaying 100ms if event isn't yet ready.

So far applies only to default, "infinite" socket timeout.

4f64f6bfd3 extmod/modlwip: Still process remaining incoming data of a closed socket. 
It can happen that a socket gets closed while the pbuf is not completely
drained by the application.  It can also happen that a new pbuf comes in
via the recv callback, and then a "peer closed" event comes via the same
callback (pbuf=NULL) before the previous event has been handled.  In both
cases the socket is closed but there is remaining data.  This patch makes
sure such data is passed to the application.

6d2e9e70b3 extmod/modlwip: Check for state change during recv busy-wait loop. 
For example, the peer may close the connection while recv is waiting for
incoming data.

4deb4936d5 extmod/modlwip: socket->incoming changed by async callbacks, must be volatile. 
Otherwise for code like:

while (socket->incoming == NULL) {
    LWIP_DELAY(100);
}

a compiler may cache it in a register and it will be an infinite loop.

404dae80a9 unix, stmhal: Introduce mp_hal_delay_ms(), mp_hal_ticks_ms(). 
These MPHAL functions are intended to replace previously used HAL_Delay(),
HAL_GetTick() to provide better naming and MPHAL separation (they are
fully equivalent otherwise).

Also, refactor extmod/modlwip to use them.
