Added handling of HI_DCI0_config requests at UE MAC. Eliminated calls to PHY functions from utilized UE MAC functions (e.g., ue_send_sdu) to support phy_stub operation mode.

Updated handling of DL_config and Tx_req pdus in phy_stub_UE to be compliant with nfapi callback functions

Added MAC level state variable for the UE and control mechanisms to ensure the correct operation of the UE MAC state machine.

Added remaining fill_harq indication functions + the functionality to handle ul_config request pdus arriving from nfapi-vnf: trigger the appropriate UE_MAC and fill_indication functions to prepare the UL_indications which will be put into the socket for transfer back to vnf. Main changes within phy_stub_UE().

Added fill functions for rx, crc and sr indications in phy_stub_UE. These functions will be getting called directly from the MAC layer of the UE. Rest of fill functions remain to be added.

TODO: if the UE did random access (followed by a MAC uplink with
CRNTI) because none of its scheduling request was granted, then
according to 36.321 5.4.4 the UE's MAC will notify RRC to release
PUCCH/SRS. According to 36.331 5.3.13 the UE will then apply
default configuration for CQI reporting and scheduling requests,
which basically means that the CQI requests won't work anymore and
that the UE won't do any scheduling request anymore as long as the
eNB doesn't reconfigure the UE.
We have to take care of this. As the code is, nothing is done and
the UE state in the eNB is wrong.

- change target values
- change upper/lower limit to trigger a tpc
- don't use ul_cqi from SR

The value of ul_cqi is not convincing, for both PUSCH and PUCCH,
more work/analysis is required.

added deactivation of ULSCH harq process after 3rd retransmission. Avoids problem of accumulating failed RA processes.

Adjustment for received power calculation in eNB pusch procedures. Added factor to account for mcs (mimic the power control adjustment in UE).
activated periodic trace for PHR/PUSCH SNR/PUCCH SNR in MAC.

- better ulsch harq management in phy (maybe not over)
- don't do schedule_CSI if UE not in RRC_CONNECTED (not sure if correct)
- don't call find_ulsch in fill_dci0
- some spaces cleaned
- log improved

this is not handled correctly as of now, let's crash

- re-use ta_timer
- when ta_timer is running:
  - no TA sent to UE
  - no TA from UE (for UE to have time to apply previous TA command)
- decrease ta_timer every TTI
- be careful to use correct value of ta_update (31 means no TA)

Maybe not correct, to be checked.

handling of PDCCH order. stoping UE-specific scheduler during RA procedure. checking for DCI format (resource allocation) to not overwrite resource_block_coding for format 1A DCIs.

put 50 PRB back in default enb configuration. added handling of UE release in L1/L2. detection of stale ULSCH configuration

removal of LOG_I put for debugging.
