Make conn->flags atomic

      The connection flags being a non atomic field means that two threads updating the flags can race and their RMW cycles overlap resulting in an invalid state for that field.

      This is incorrect and conn->flags should be converted to conn->flags_atomic . Then the F_SET_ATOMIC and related macros should be used to manipulate the field.
