sock: introduce SO_MEMINFO getsockopt
Allows reading of SK_MEMINFO_VARS via socket option. This way an application can get all meminfo related information in single socket option call instead of multiple calls. Adds helper function, sk_get_meminfo(), and uses that for both getsockopt and sock_diag_put_meminfo(). Suggested by Eric Dumazet.
