For whatever reason we need N_TA_offset to be 0 for the basic simulator
to function properly.

This is more a hack than a proper solution. More analysis is needed
to understand what happens and what should be really done.

In TDD mode the eNB does not output data all the time,
only in downlink and special subframes.

The basic simulator needs a continuous stream of samples.

So let's fill the blank with silence.

Conflicts:
	targets/RT/USER/lte-ru.c

When compiling in debug mode, the 'inline' semantics of C99 led to the errors:

/roux/w25/openairinterface5g/common/utils/LOG/log.c:479: undefined reference to `log_header'
libUTIL.a(log.c.o): In function `log_dump':
/roux/w25/openairinterface5g/common/utils/LOG/log.c:502: undefined reference to `log_header'
collect2: error: ld returned 1 exit status

Let's use static instead of inline.

Summary of changes:
- work on flexran
- work on X2
- new implementation of ITTI
- code cleanup
- bug fixes

If the IP address for X2AP is not good, the error message reported
was very unclear. Attempt to make it better.

This commit manually reverts the commits:
- 97c69dc4
- 3278aa49

The basic simulator was not functional anymore because
the UE did not send RRCConnectionSetupComplete due to
some problem in the PDCP layer, most probably.

This break was there and went away, for whatever reason...
