Connection sockets now have the proper family/type/proto values.

Fix argument handling bug in socket(f,t,p) call.
Fix some comments.

 - only AF_INET and AF_UNIX address families are supported
 - no asynchronous I/O
 - no read/write operations (use send/recv instead)
-- no flags on send/recv operations
+- no flags on sendto/recvfrom operations
 - no setsockopt() call
 
 Interface:
 
 - socket.gethostbyname(hostname) --> host IP address (string: 'dd.dd.dd.dd')
-- socket.getservbyname(server, type) --> port number
-- socket.socket(family, type) --> new socket object
+- socket.getservbyname(servername, protocolname) --> port number
+- socket.socket(family, type [, proto]) --> new socket object
 - family and type constants from <socket.h> are accessed as socket.AF_INET etc.
 - errors are reported as the exception socket.error
 - an Internet socket address is a pair (hostname, port)
