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 generalissue28261.

note that#15988 also left 3 changes for this issue to fix, as can beseen by searching for '29832' in the comments ofPR 668.for example, this issue should also fix the following inconsistenterror 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 myWindows 10 and Ubuntu 16.04 VM, i.e. all of the changes, except forthe 'unsupported CAN protocol' message, and the changes of the codethat handles the PF_SYSTEM family.

Should i remove the code that i wasn't able to test from the PR, andleave 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 pointthat out, and i would try to set up this VM.)
