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:

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...

Note: we don't include the last commit from origin/recode_itti_from_scratch
because it is just astyle formatting. As of today we don't enforce
astyle and including this work would lead to future merge conflicts.
A proper process to enforce astyle has to be put in place. In the
meantime, no astyle allowed in commits if the changes are too big
and not relevant to work done.
