A few prototypes are not part of any header files, leading to
corresponding compiler warnings.
This commit adds the missing prototypes to sysmo_l1_if.h.

In order to use this feature, sysmoBTS requires option "-M", otherwise
the traffic is forwarded through socket interface.
This is essential, if PCU runs on processor of sysmoBTS. The reaction
time and delay of PDTCH frames could heavily degrade proper packet flow.
