Merge remote-tracking branch 'origin/Develop-nr-threequarter_fs-80mhz-x310' into integration_2019_w18

1. Fix code generated from ASN.1 of F1AP v15.4.0 failed to be compiled
2. Fix incorrect UPER encoding for empty extensible SEQUENCE in 38.331
3. Fix the problem that duplicate type names exist in OPEN TYPE

The changes made in this branch is to enable -E(threequarter sampling rate) option for mu=1 and 217PRB(ie; 80 MHz) to run on USRP x310.

Final --phy_simulators warning removals for this branch, and former polar coding function corrections

--phy_simulators warning removals, except for nr_dlsim. Polar coding old implementation's approximation and a priori information options needs to be corrected or removed

first version of UE FAPI handling for DLSCH. paramters from DCI are now handled by MAC and passed back to the PHY to program PDSCH. Still need to check parameters and take them into account in PHY.
