Trivial changes: whitespace and modes. Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>

lib9/dial: fix addrlen in connect() and bind() On some systems, the third argument of connect() and bind() is expected to be the length of the address family instead of the length of the sockaddr structure. R=rsc http://codereview.appspot.com/6489072

lib9/dial: add support for IPv6 The function p9dialparse() returns the host as a sockaddr_storage structure instead of a u32int, to be able to handle both IPv4 and IPv6 addresses. Because the sockaddr_storage structure also handle port numbers and Unix path names, there is no longer need to set them in the calling functions. However, these values are still returned for convenience. The sockaddr_in and sockaddr_un structures have been replaced by sockaddr_storage to handle Unix, IPv4 and IPv6 sockets. Names and addresses are resolved using either gethostbyname() or getaddrinfo() functions. The getaddrinfo() function is documented in RFC2553 and standardized since POSIX.1-2001. It supports both IPv4 and IPv6 addresses. The gethostbyname() function is deprecated since POSIX.1-2008. However, some libc implementations don't handle getaddrinfo() properly, thus we preferred to try gethostbyname() first. I've tried to preserve most of the old code logic to prevent from surprising or unwanted behavior. R=rsc http://codereview.appspot.com/6255068

unix is not a variable name
