Andre Puschmann c5f52adfba nas: fix issue in which NAS wouldn't allow to attach once it failed

EPS bearers.

The patch also extends the SS to support AT commands to enable/disable
data services and now succesfully passes TC_9_2_2_1_7

Harald Welte 2e426948fe [ENB] Add CFSB support 
This commit introduces CSFB (circuit switched fall-back) capabilities to
srsLTE.  Actually, all the eNB has to do is to send a
RrcConnectionRelease with the RedirectedCarrierInfo IE.

The MME triggers this by the S1AP CS Fallback Indicator IE, which may
be present either in the Initial Context Setup Requst or in the
UE Context Modification Request.

As srsLTE has no support for the UE Context Modification Request at all
yet (!), basic support for this message is introduced in this patch.

Both Mobile Originated and Mobile Terminated CSFB with a coupel of
different UE models have been verified using this patch in a setup
consisting of srsENB attached to an undisclosed EPC connected via SGsAP
to a complete  Osmocom 2G network.

Closes: #358
Closes: #363

RRC-PHY interface (#639) 
RRC-PHY interface refactor. Moved RRC-MAC interface to rrc_asn1_utils and created RRC-PHY interface also in rrc_asn1_utils. All ASN1 includes should be made from rrc_asn1_utils only keeping ue_interfaces clean of ASN1

Tested with different common and dedicated configurations (64QAM UL, 256QAM, CA, SRS enabled/disabled, etc)
