Sakthivel Velumani cf0206e7c6 Fix scheduler for long prach 
Long PRACH extends beyond a slot. Changes necessary to mark future slots
that may contain prach in ru, phy and mac functions.

In RU, the PRACH IDFT is done only after receiving last slot and marks
for L1 to start processing. The L1 processes at the last prach slot and
reports to MAC with the first slot index.

In MAC scheduler, the VRB for future slots are also marked as used.
PRACH scheduler is called in advance one frame minus num prach slots.

Melissa Elkadi 4dd579e042 int32_t to c16_t conversion 
This commit includes changes to the function
footprints for vaiours NR UE and gNB functions.
It does not updated the LTE code. For functions
shared by both LTE and 5G, we maintained the original
LTE footprint and argument structure.

Several of the simulators that use these functions
have been updated as well. The specific usage of these
functions which index into the int32_t buffers and
treat the first int16_t and the real and the second
as the complex should be modified in the near future.
