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

Andre Puschmann d9577f0e1e suppress type-limit warning issued by some compilers by making var signed
Used to happen with older gcc giving:

"rlc_am.cc:1791:22: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]"

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)

Francisco Paisana 67d6a25194 Moving mac timers to stack timers (#638)
* first step towards moving MAC timers to stack. Mac is still using its own timers. srslte::timers class can be restructured.

* moved timers out of the UE MAC

Francisco Paisana bb0dbf0f1c created a asn1 utils with helper functions and types related to the asn1. These types/functions will help isolate the rrc_asn1 lib from most of the layers, reducing this way the compile times, and leading to better isolation. This will also make the transition to NR smoother. I removed the asn1 types from the NAS and USIM interface so far. 6 years ago

Andre Puschmann 58763fb714 stack: move initialization of log object into ctor
this fixes the issue when the stack is torn down if, for example,
the radio couldn't be loaded correctly. it will hence call stop() on all stack
components which are not initialzized yet, and logging therefore doesn't work.
the log object is know during contruction time and therefore can be passed
in as soon as possible.
