getsockaddrarg() is an internal C function in the socket module implementation used in a number of socket methods (bind(), connect(), connect_ex(), sendto(), sendmsg()) for creating C structure sock_addr_t from Python tuple. Error messages raised when pass incorrect socket address argument to these function contain the name "getsockaddrarg" despite the fact that it is not directly exposed at Python level, nor the name of standard C function.

>>> import socket
>>> s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> s.bind(42)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: getsockaddrarg: AF_INET address must be tuple, not int
>>> s.bind(())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: getsockaddrarg() takes exactly 2 arguments (0 given)

I think that error messages shouldn't refer to non-existing function "getsockaddrarg()".

This issue is a part of more general issue28261.

note that #15988 also left 3 changes for this issue to fix, as can be
seen by searching for '29832' in the comments of PR 668.

for example, this issue should also fix the following inconsistent
error messages:
>>> socket.socket(family=socket.AF_INET6).bind(('::1', -1))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: getsockaddrarg: port must be 0-65535.
>>> socket.socket(family=socket.AF_INET6).bind(('::1', -1 << 1000))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

here is a dirty script to test my PR.

the script contains tests to anything I managed to test using my
Windows 10 and Ubuntu 16.04 VM, i.e. all of the changes, except for
the 'unsupported CAN protocol' message, and the changes of the code
that handles the PF_SYSTEM family.

Should i remove the code that i wasn't able to test from the PR, and
leave such changes to someone that is able to test it?

(of course, if there is some way i can do it using a VM, please point
that out, and i would try to set up this VM.)
