modifications for TDD and IF4p5 (in particular TDD). Both in RRU and RAU components. Monolithic is unchanged.

added LUT for finer-grain ULSCH power measurement compensation based on TBS. Still seems too high, to be checked some more.

addition of MPDCCH format 5. X_u_br sequences for BL/CE UE support and bugfixes in rx_prach0 for eMTC.

L1/L2 scheduling extensions for BL/CE operation, BR random-access procedure, BR PRACH detection. Still untested, but compilation succeeds. Missing elements in L2 - PUSCH programming for Msg3, Msg4 retransmission programming for BL/CE. DLSCH/ULSCH programming for UE-specific DLSCH/ULSCH for BL/CE

Note: this commit is work in progress. Contains initial integration of NFAPI data structures which are tested for TX path. RX path to follow.

- import RRC ASN.1 defintions from the specifications
  (file openair2/RRC/LITE/MESSAGES/asn1c/ASN1_files/RRC-e10.asn)
  contrary to rel8/10, all modules have been imported, maybe it's too much
  to refine in case of problems
- deal with rel14 in fix_asn1
- all code that was for Rel10 is now for Rel10/Rel14
- some incompatible changes (mostly in naming) were resolved in favor
  of rel14, see in openair2/RRC/LITE/defs.h
- unsure about the rlc layer, some arrays have changed (values appended),
  I only changed the definition and in tests in the code, I changed
  the index limit, maybe it's not enough

Rel14 is the default compilation mode.

The compilation line was:
    ./build_oai --eNB -w USRP

The file openairinterface5g/cmake_targets/log/lte-softmodem.Rel10.txt
has been checked and all LOG_X (and 'msg') warnings have been fixed.

changed the memory allocation of txdataF and beam_weigths

Beamforming is now only done when necessary. This patch is based on one from enhancement-10-harmony.

reduced the max number of antenna ports to 6 to save memory (we are not using antenna port >5 anyway)
mult_cpx_conj_vector can now also do multiply add
beam_precoding now uses mult_cpx_conj_vector

Conflicts:
	openair1/PHY/MODULATION/beamforming.c

Some of them might not be correctly handled.
I put /* TODO: XXX */ where I didn't know if
the fix was correct.
