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

Changes on srsENB mutexing logic to fix general race condition and deadlock issues (#229)
* fixed some issues with the UL scheduling

* Hack to fix UL scheduler

* minor fix

* Cleaned up code and fixed issue with the update_allocation function

* fixed the console printing in the enb

* log/console fix

* fixed the log print

* added a normalization factor

* RLC: entity uses dynamic instances. Simplified stop/reset/reestablish procedure. Added non-blocking interface

* Limit decimals in metrics stdout

* Changed mutexes to rwlock in RLC/RRC/MAC/PDCP to fix race conditions when removing users

* Fix deadlock bug for MIMO

* Remove headers

* Fix missing unlock causing overflows

* Do not decrease CQI when PUCCH (this is a temporal fix, requires to reduce the maximum MCS)

* Fix mutex unlock in worker

* Configurable RLC tx buffer. Default to 512 for enodeb

* Check NULL SDU in write_sdu()

* Protect RLC objects and tx_queue from being destroyed while using it

* Remove superfluous code

* Disable SIB logging

* Fix block_queue for enb
