PPP, PPPoE: rename PPPOE_TODO to PPPOE_SCNAME_SUPPORT, prepare service name and concentrator support

Browse Source 
Rename PPPOE_TODO to PPPOE_SCNAME_SUPPORT because this is the only
feature enclosed by them. Prepare for proper service name and
concentrator name support by moving PPPOE_SCNAME_SUPPORT define to
ppp_opts.h.
