fullread has been changed, so get_event too, and the callers also
for the moment the callers crash, enb.c will be a bit more clever,
the others to see...
It was wrong.
Plus it is starting work so as to make enb.c not crashing if
the tracee goes away (maybe also textlog and vcd, but those are of
less importance).
The local tracer now waits for the remote tracer to connect,
that's no more the other way around.
All the remote tracers (textlog, enb, vcd) have also been converted.
as special events.
If we store all received events to a file, this dump is now
self-contained. Helps to analyze traces.
Some functions have also been factorized in the process, too much
duplication.
(Also tracer/Makefile was forgotten in previous commit, included
in this one...)
