Fix socket(fileno=fd) by auto-detecting the socket's family, type,
and proto from the file descriptor. The auto-detection can be overruled
by passing in family, type, and proto explicitly.
Without the fix, all socket except for TCP/IP over IPv4 are basically broken:
>>> s = socket.create_connection(('www.python.org', 443))
>>> s
<socket.socket fd=3, family=AddressFamily.AF_INET6, type=SocketKind.SOCK_STREAM, proto=6, laddr=('2003:58:bc4a:3b00:56ee:75ff:fe47:ca7b', 59730, 0, 0), raddr=('2a04:4e42:1b::223', 443, 0, 0)>
>>> socket.socket(fileno=s.fileno())
<socket.socket fd=3, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('2003:58:bc4a:3b00::%2550471192', 59730, 0, 2550471192), raddr=('2a04:4e42:1b:0:700c:e70b:ff7f:0%2550471192', 443, 0, 2550471192)>

* Fix compilation of the socket module on NetBSD 8.
* Fix the assertion failure or reading arbitrary data when parse
a AF_BLUETOOTH address on NetBSD and DragonFly BSD.
* Fix other potential errors and make the code more reliable.
Fix timeout rounding in time.sleep(), threading.Lock.acquire() and
socket.socket.settimeout() to round correctly negative timeouts between -1.0 and
0.0. The functions now block waiting for events as expected. Previously, the
call was incorrectly non-blocking.
* bpo-27584: New addition of vSockets to the python socket module
Support for AF_VSOCK on Linux only
* bpo-27584: Fixes for V2
Fixed syntax and naming problems.
Fixed #ifdef AF_VSOCK checking
Restored original aclocal.m4
* bpo-27584: Fixes for V3
Added checking for fcntl and thread modules.
* bpo-27584: Fixes for V4
Fixed white space error
* bpo-27584: Fixes for V5
Added back comma in (CID, port).
* bpo-27584: Fixes for V6
Added news file.
socket.rst now reflects first Linux introduction of AF_VSOCK.
Fixed get_cid in test_socket.py.
Replaced PyLong_FromLong with PyLong_FromUnsignedLong in socketmodule.c
Got rid of extra AF_VSOCK #define.
Added sockaddr_vm to sock_addr.
* bpo-27584: Fixes for V7
Minor cleanup.
* bpo-27584: Fixes for V8
Put back #undef AF_VSOCK as it is necessary when vm_sockets.h is not installed.
* Added support for CAN_ISOTP protocol
* Added unit tests for CAN ISOTP
* Updated documentation for ISO-TP protocol
* Removed trailing whitespace in documentation
* Added blurb NEWS.d file
* updated Misc/ACKS
* Fixed broken unit test that was using isotp const outside of skippable section
* Removed dependecy over third party project
* Added implementation for getsockname + unit tests
* Missing newline at end of ACKS file
* Accidentally inserted a type in ACKS file
* Followed tiran changes review #1 recommendations
* Added spaces after comma
sock_addr_t is used to define the minimum size of any socket address on
the stack. Let's make sure that an AF_ALG address always fits. Coverity
complains because in theory, AF_ALG might be larger than any of the other
structs. In practice it already fits.
Closes Coverity CID 1398948, 1398949, 1398950

* Replace "fd = -1" with "fd = INVALID_SOCKET"
* Replace "fd < 0" with "fd == INVALID_SOCKET": SOCKET_T is unsigned on Windows
Bug found by Pavel Belikov ("Fragment N1"):
http://www.viva64.com/en/b/0414/#ID0ECDAE
Issue #26590: Implement a safe finalizer for the _socket.socket type. It now
releases the GIL to close the socket. Use PyErr_ResourceWarning() to raise the
ResourceWarning to pass the socket object to the warning logger, to get the
traceback where the socket was created (allocated).
Issue #26567:
* Add a new function PyErr_ResourceWarning() function to pass the destroyed
object
* Add a source attribute to warnings.WarningMessage
* Add warnings._showwarnmsg() which uses tracemalloc to get the traceback where
source object was allocated.
Issue #26227: On Windows, getnameinfo(), gethostbyaddr() and gethostbyname_ex()
functions of the socket module now decode the hostname from the ANSI code page
rather than UTF-8.
PyUnicode_AsEncodedString() instead of calling the encode() method of the
host, to handle correctly custom string with an encode() method which doesn't
return a byte string. The encoder of the IDNA codec is now called directly
instead of calling the encode() method of the string.
Use _PyTime_FromSeconds() to initialize the default socket timeout to -1
second, instead of -1 nanosecond which causes rounding issues in
internal_select().
* Use the new _PyTime_FromSeconds() function to set the timeout to -1 second
for socket.settimeout(None). It avoids a special case in internal_select()
because of a rounding issue: -1 nanosecond is rounded to 0 millisecond which
means non-blocking, instead of blocking.
* Check if the interval the negative in sock_call_ex() instead of doing the
check in internal_select(). sock_call_ex() remembers if the socket has a
timeout or not, which avoids a race condition if the timeout is modified in a
different thread.
instead of raising InterruptedError if the connection is interrupted by
signals, signal handlers don't raise an exception and the socket is blocking or
has a timeout.
socket.socket.connect() still raise InterruptedError for non-blocking sockets.
The BEGIN_SELECT_LOOP and END_SELECT_LOOP macros of socketmodule.c don't handle
EINTR. Functions using these macros use an inner loop to handle EINTR, but they
don't recompute the timeout.
This changes replaces the two macros with a new sock_call() function which
takes a function as a parameter. sock_call() recomputes the timeout, handle
false positive and handle EINTR.
Call PyErr_CheckSignals() immediatly if connect() or select() fails with EINTR
in internal_connect().
Refactor also the code to limit indentaton and make it more readable.
