This commit permits one UE to connect.
It implements some very basic support for
SchedDlTriggerReq and SchedDlConfigInd
(and also a bit SchedDlRlcBufferReq)
(see schedule_ue_spec).

There are many assumptions everywhere.
This is very preliminary work.

We may discuss about this, I personally prefer to avoid
memory allocations.

Some more work is needed. For the moment we use minifapi.c
as implementation of scheduler. In the future we will link
with some externally provided scheduler.
