Andre Puschmann 0ef8e1fdac rrc: include pci when logging serving cell measurement 
this should facilitate easier log parsing and plotting

[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

Francisco Paisana 7f8af023b8 added a callback that always gets triggered when the phy cell selection completes. This callback checks if cell selection failed, and if so, sets the rsrp of the selected cell to -infinity 4 years ago
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 e981d5ee70 rrc,ue: refactor wait conditions before transition to RRC idle 
before entering RRC idle, after receiving a RRC connection release for example,
we need to wait until the RLC for SRB1 or SRB2 have been flushed, i.e.
the RLC has acknowledged the reception of the message.

Previously we have only waited for SRB1 but the message can also be received on SRB2
and in this case both bearers need to be checked.

The method is now streamlined to check both SRBs and is also used when
checking the msg transmission of an detach request.
