Andre Puschmann 0ef8e1fdac rrc: include pci when logging serving cell measurement 
this should facilitate easier log parsing and plotting
if the cell measurements _always_ include the PCI, even
in the case of the serving cell

Andre Puschmann ddbf4e1645 metrics_stdout: print new table header if neighbour cells change 
this fixes an issue where the stdout metrics isn't readable if the only
neighbour cell gets removed during the 10s where no table header is printed.

Andre Puschmann b616944a13 ue,rrc: fix security config during HO/reestablishment 
we fix a number of very related issues for HO/reestablishment
in the success/error case:

* this patch removes the hard-coded check that intra-cell HO aren't
allowed. There are cases where eNBs use this method to update
the security context.

* the patch also fixes an issue after failed HO where the security context
of the source eNB should be used for the reestablishment.

* update security keys according to specs when mobilitycontrol
indicated change of key

Andre Puschmann 6827c2df21 rrc_meas: disable layer3 filtering until quantity config is received 
the filter alpha was initialized to zero by default which causes an
issue because the first measurement for a cell can't be updated,
because the filtering function will always return the current value.

According to 36.331 Sec 5.5.3.2 Note 2, a k-value of 0 should turn
off filtering, which should be used as the default value until
an update is received from the network.

Andre Puschmann aec18a93d1 mux,bsr: refactor UL buffer status reporting 
this patch fixes the UL BSR as per TS 36.321, it includes following
main changes:

* report UL buffer state to reflect the UEs transmit buffer after
  the MAC UL PDU containing the BSR has been built.
  In other words, if the UE, for example, can transmit all outstanding
  data in an UL grant, it will not report any pending data to transmit.

* refactor MUX routines and subheader space calculation
