[S] Change in libosmo-abis[master]: e1_input: add new driver callback function: line_create

dexter has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-abis/+/32400 ) Change subject: e1_input: add new driver callback function: line_create ...................................................................... e1_input: add new driver callback function: line_create When a line is created using e1inp_line_create, then the line data structures are initialized and the line is registered in the line list. struct e1inp_line also contains driver specific sub structs that, depending on the driver, might also need some initialization. At the moment is no way. Let's add a line_create callback that, when populated by the driver, is executed on line creation.
