just a quick fix before merge, the real solution
is to disable pusch scheduling in the prach, to be
done later

- compile with warning enabled (changes in CMakeLists.txt)
- remove warnings that were present

- allocate memory, memory on stack does not survive the function
- avoid uint32_t, use a char buffer, for endianness neutrality

basically the T_xx variables are int, not uint

The warning was:

The root cause was that the array pucch_format_string was not in sync with
the structure. (This plus why force its size and put \0 in the string...)

phy_init_lte_ue_signal was renamed init_lte_ue_signal in openair1/PHY/INIT/defs.h
maybe it's the opposite that should have been done?

Functions used in one file and defined in another may have been
declared in the wrong header file.

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

Old values valid for a previous UE have to be reset for the new UE.

introduce a new function to deal with this special case

Compilation will fail if UHD is not installed, there is no need
to check. Plus the test is wrong when you install UHD somewhere
else.

- UE_id 0 is for rnti 65535 (sib)
- UE_id 1 is for rnti 65534 (this is a hack)
- UE_id 2 is for rnti 2     (RA RNTI as of today's code/config)
- we start enb by displaying UE_id 3
- there was a bug: we need to lock when resetting UE ids (reset_ue_ids)

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

see commit 622b919b

TODO: if the UE did random access (followed by a MAC uplink with
CRNTI) because none of its scheduling request was granted, then
according to 36.321 5.4.4 the UE's MAC will notify RRC to release
PUCCH/SRS. According to 36.331 5.3.13 the UE will then apply
default configuration for CQI reporting and scheduling requests,
which basically means that the CQI requests won't work anymore and
that the UE won't do any scheduling request anymore as long as the
eNB doesn't reconfigure the UE.
We have to take care of this. As the code is, nothing is done and
the UE state in the eNB is wrong.

removed "short_offset" code from normal_prefix_mod. removed static declaration in PHY_ofdm_mod which was a cause for problems when parallelizing FFTs for FEP TX.

- change target values
- change upper/lower limit to trigger a tpc
- don't use ul_cqi from SR

The value of ul_cqi is not convincing, for both PUSCH and PUCCH,
more work/analysis is required.

put pucch metric into uci->stat before calling harq_indication. Fixes an issue with PUCCH1 SNR measurements coming from HARQ.

added deactivation of ULSCH harq process after 3rd retransmission. Avoids problem of accumulating failed RA processes.
