    kernel - Fix auto port assignment collision in network code
    
    * When the SO_REUSEADDR or SO_REUSEPORT socket option is set on a
      socket undergoing automatic lport assignment, the auto network port
      assignment code in the kernel improperly ignores collisions against
      ports assigned to wildcard sockets and may assign the same port.  This
      causes later connect() calls to fail.
    
    * Can cause gdb services to sometimes fail to connect.
    
    * Fixed by ignoring the options for the purposes of finding an unused
      port.
