initialization of 7.5 kHz tables moved to RU initialization so that IF4p5 RRU doesn't crash anymore.

In the eNB it's not really used for the moment because there
is a limitation to uplink scheduling. In
openair2/LAYER2/MAC/eNB_scheduler_ulsch.c we have:

            while (((rb_table[rb_table_index] > (N_RB_UL - 1 - first_rb[CC_id]))
                    || (rb_table[rb_table_index] > 45))

That limits uplink scheduling to at most 44 RBs. The 768 case is for
64 RBs.

Bug only occurs when compiling without AVX2

With 50 RBs and 100 RBs the UE crashes in the basic simulator
because of false detection of DCIs.

Putting nothing in the unused REs in the DCI instead of random
bits solves this issue and let the basic simulator run with 50 RBs
and 100 RBs.

Note that in the real UE the problem needs to be solved because
the channel may lead to false DCI detection and the consequent
crashes have to be solved. This commit sort of "hides" the issue
to have the basic simulator functional.

Note also that putting nothing in the unused REs in the DCI should
be the normal general case. But it has not been tested with anything
but the basic simulator so the previous code is left.

Use common log mechanism in layer 3, mapping specific macros to common ones and extending common log utilities to support specific layer3 requirements

LOG_F replaced by LOG_DUMPMSG. Add a generic function to dump a buffer or message. Go on with LOG_M implementation improvement. Remove redundant options to enable/disable logs.

Subframe 6 may be an MBMS subframe, and timing sync does not (yet) work on MBMS subframes.

A better solution has to be found.

One of the optimized RE allocation function does not work properly
and generates some decoding errors with a COTS UE. Let's use the
generic function for the moment, while analyzing what is wrong.

more flexible to support 4x4 system.
