* don't enable ipv6 by default due to privacy concerns
* move list of board support for ipv6 to socketpool documentation
* removed wifi.supports_ipvx properties
* throw an exception when start_dhcp_client(ipv6=True) but not supported
cpython socket objects have a `type` property which gives their
type as an integer (e.g., SOCK_STREAM). Add this for compatibility with
standard Python. It's needed for ssl, which currently just grabs the
value directly from an internal structure (naughty!)
We mark all protocols with their type using MP_PROTO_IMPLEMENT,
and checking in mp_get_stream{,_raise}.
This was not turning up as a problem in tests until a (new, not yet
commited) change to jpegio caused a segfault because a type implementing
a different protocol was passed in to mp_get_stream.
By using 0 (instead of MP_QSTR_protocol_stream) as the marker for
objects implementing the standard micropython stream protocol, the
number of CIRCUITPY-CHANGEs is minimized.
gaierror(-2) is raised in the failure case of getaddrinfo. This is
compatible with cpython's socket module.
Typical session:
```
>>> import socketpool
>>> import wifi
>>> socket = socketpool.SocketPool(wifi.radio)
>>> try: socket.getaddrinfo("boo", 0)
... except socket.gaierror as e: ee = e
...
>>> type(ee)
<class 'gaierror'>
>>> ee.errno == socket.EAI_NONAME
True
>>> ee.strerror
'Name or service not known'
>>> raise ee
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 1, in <module>
gaierror: (-2, 'Name or service not known')
```

The standard Python 'fix' for 'send()' returning prematurely is to
use the 'sendall()' method instead. However, this method was not
available. adafruit_httpserver will probably need to code a version
of it for older versions or for Airlift, but when it's available
this code works (Tested on picow sending 8192 bytes) and may be more
efficient.
(implementing 'sendall' in python should take care to slice a memoryview
rather than the original buffer)
Originally, black_bindings found each contiguous "//|" block and sent
it to black independently. This was slower than it needed to be.
Instead, swap the comment prefix: when running black, take off
"//|" prefixes and put "##|" prefixes on all un-prefixed lines.
Then, after black is run, do the opposite operation
This more than doubles the overall speed of "pre-commit run --all",
from 3m20s to 55s CPU time on my local machine (32.5s to under 10s
"elapsed" time)
It also causes a small amount of churn in the bindings, because
black now sees enough context to know whether one 'def' follows another
or ends the 'def's in a 'class'. In the latter case, it adds an extra
newline, which becomes a "//|" line.
I'm less sure why a trailing comma was omitted before down in
rp2pio/StateMachine.c but let's roll with it.
