PPP, CCP, added receive and transmit chosen protocols in ccp_flags_set() (renamed ccp_set())

We need to know which methods were chosen when CCP is up, this used to be done
using ccp_test() which we are in the process of removing.

Using non-existing method 0 instead of -1 in CCP for unset method, allowing
type change from s16_t to u8_t for method.
