moved nr_dci_size out of scheduler_phytest

an assertion fails in gnb (need to be fixed)

ENABLE_ITTI macro removal, modified telnet server to support all executables, modified record player to finalize switch to run-time option and allow usage with any device

nr-ip-UL-nos1: Integrate NR MAC PDU structures for the Uplink. Currently supporting only data SDUs, Control Elements to be added.

scheduling of PUCCH on MAC, passing PUCCH FAPI down to PHY (to be finished), filling DCI structures according to PUCCH (to be finished)

- now the UE is passing again data to the upper layers in noS1 mode
- minor cleanups

nr-ip noS1 uplink: Uplink IP traffic successfully received at the IP TUN interface of the gNB now. Logs cleanup.

nr-ip noS1 uplink integration (testing with RFSIMULATOR only): Uplink IP packets received at the gNB and reaching at pdcp layer. Asserion error at pdcp_fifo_flush_sdus when trying to write on the nas socket

 - configure_fapi_dl_pdu is handling the nfapi_nr_dl_config_request_pdu
 - while configure_fapi_dl_Tx is now handling the nfapi_tx_request_pdu

this was necessary because the computation of the TBS size is needed in the phytest scheduler
before even knowing if there is any data to transmit. The tx_request_pdu must be handled instead
only when there is data to transmit.
