Ahmed Hussein 9a857e4486 Adopting the dynamic implementation of DMRS at the gNB side 
- Using the implemented DMRS functionalities at the MAC layer at the gNB side
  - Removing is_dmrs_symbol function
  - Temporary implemetation at the UE side considering DMRS symbol is at the 1st PUSCH symbol,
    until the nFAPI structs for DMRS is adopted at the UE side

Robert Schmidt 8ffe5b4920 Rename UE_list_t to UE_info_t, UE_list_t separate struct 
UE_list_t is now used as a separate list. It can be e.g. used in the
scheduler to mark groups of users. The original UE_list_t is renamed to
UE_info_t to reflect that it is a container for information about UEs.

Robert Schmidt fd6618dc1c Simplify preprocessor, retain functionality 
* Simplify store_dlsch_buffer()
* Simplify assign_rbs_required()
* Simplify dlsch_scheduler_pre_processor_partitioning()
* Simplify dlsch_scheduler_pre_processor_accounting() and dlsch_scheduler_pre_processor_accounting_allocate()
* Simplify allocation printing

The original functions used in the fairRR scheduler have been moved to
eNB_scheduler_fairRR

Robert Schmidt 4462e2d710 Remove unused/broken code in preprocessor 
* Remove MIMO_mode_indicator: it is simply not used ATM
* Remove min_rb_unit as parameter: function auto-detects
* Remove commented code
* Remove slice sharing/multiplexing: it is broken
* Remove UE sorting, add UE with add_new_ue() in MAC
  - UE sorting is useless overhead on every iteration, instead it should
    be governed by a scheduling algorithm (e.g., RR or PF)
  - The MAC keeps a UE list and automatically adds a UE
  - UE_list empty, set head to -1
* Remove slice_positioning: the slicing functionality is broken
* Remove unused/untested code

Robert Schmidt ffc4f464f5 Remove useless mac_proto.h include 
When a header is changed, all including files need to be recompiled,
too. Thus, including a header needlessly all over the place drives
compile times up without any reason.
