[REBASE] Make PHY non-blocking and fefactor HO procedure ( #1753 )
...
* Make PHY non-blocking and fefactor HO procedure
* makes entire PHY non-blocking through command interface
* adds dedicated queue for cell_search/cell_select commands
* refactor HO procedure to run faster, in one stack cycle. Looks closer to the specs
* force ue to always apply SIB2 configuration during reestablishment
* Run update_measurements in all workers

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.
