Andre Puschmann c0be8187c8 rlc interface: convert entire read_pdu() interface to return uint32_t 
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.

Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.

Francisco 34e39a9835 Implementation of scheduler algorithm to avoid PUCCH collisions

- At the moment PUCCH multiplexing is not considered
- The PUCCH width was increased to accommodate possible PUCCH-ACK positions
