Summary: New DHCP messages for tcpip_thread (thread-safe

Details:
I would like to add new messages in tcpip.c api for dhcp_start & dhcp_stop to
be thread-safe (with a configuration option like LWIP_DHCP_MSG to reduce
footprint).
Because now dhcp_timers are in tcpip_thread, and if we have to be able to
change from static to dhcp settings (and reverse) without fully stop/start
the stack, these messages MUST be available...
Else, if during a dhcp's timers process per tcpip_thread, the application
stop a netif's dhcp client directly with dhcp_stop, we can crash, because the
netif's dhcp field will be invalidate, but use per tcpip_thread.
Ok for you?
