- 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

-1 does not work

- 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.

internal use, no documentation, no support.

we can't use &ul_config_pdu->ulsch_harq_pdu.harq_information directly,
because that function is called for 2 cases and the substructure
harq_information is not as the same position in both cases.

switching some LOG_I to LOG_D, fixes for RRU IF4p5. It was broken after changes in configuration procedures. Some configuration file changes.
