this should facilitate easier log parsing and plotting

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

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.

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.
