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 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.

Andre Puschmann 8a064cd3a6 pass msg_type from caller when logging RRC message
before the type of some message wasn't displayed correctly,
like SIBs, for example because the logger didn't
know the filed to retrieve the type string

Xavier Arteaga b4b1ab94af SRSUE RRC: new PHY unknown sync state, cell select waits for PHY in-sync 5 years ago
Andre Puschmann 8ef0d6c6ca do not automatically consider cells for which a measurment has been received as "in sync"
the in_sync flag has been misused in some parts of the code
receiving a PHY measurement for a cell does not automatically
mean that we are "in sync", as it is used in RRC as a condition
to indicate if we are camping on cell

the in_sync/out_of_sync condition should only be altered by the
corresponding functions sent from the PHY for the currently selected
cell (and not automatically for all cells)

the commit also removes the deletion of cells which are not "in sync"
from the list of neighbor cells. Instead, RRC calls a clean-up function
peridically that deletes old cells eventually.

Francisco Paisana f2d88e5a5b simplified NAS rrc connection request procedure

made the NAS procedures more event trigger/reaction-based.
