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.

general-purpose method for lower layers to signal protocol
failures to higher layers, i.e. RRC.
In the current case, implement a direct release of the UE (enb) or
a reestablishment (UE).

enb,rrc: fix bearer re-activation after max KO
...
this patch makes sure that if RBs have been deactivated after
max KO on either the DL or the UL, they are reactivated if either
of them is working again.
UL/DL are always activated together, even if just one of them
recovers. The KO counter (or timer), however, is not stopped implicitly.
