improved PPP API, added ppp_reopen()

Browse Source 
This is now the user choice to re-establish the session in the link status callback
by either calling the ppp_reopen() to re-establish or ppp_delete() to free the PPP
control block. Without user intervention, the PPP control block now stay in the dead
phase, allowing the user to re-establish or delete the control block later.
