mISDN: Add E-Channel logging features
New prim PH_DATA_E_IND.
- all E-ch frames are indicated by recv_Echannel(), which pushes E-Channel
frames into dch's rqueue
- if dchannel is opened with channel nr 0, no E-Channel logging
is requested
- if dchannel is opened with channel nr 1, E-Channel logging
is requested. if layer1 does not support that, -EINVAL
in return is appropriate
