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.

enb,rrc: split RLF counter and timer handling for DL/UL/RLC
...
this patch splits the counter and timer handling for PHY DL, PHY UL,
and RLC errors and makes sure that, for example, a successful DL
does not cancel the UL RLF timer, and vice versa.
They all use the same timeout value which is user-configurable.
