proc: implement proc_single_file_operations
Currently many /proc/pid files use a crufty precursor to the current seq_file api, and they don't have direct access to the pid_namespace or the pid of for which they are displaying data. So implement proc_single_file_operations to make the seq_file routines easy to use, and to give access to the full state of the pid of we are displaying data for. Signed-off-by: Eric W.
