+Add type information per facility : it will help having a standard way
+to understand information coming from both kernel space and user space, and deal
+easily with 64 bits kernel with 64 and 32 bits processes (and with size_t know
+at compile time which can differ inside the same process from one library to
+another).<br>
+fix structures alignment, array and sequences too. -> trace dynamic.<br>
+add per facility alignment (inside structures).<br>
+add control of alignment.<br>
+add user space tracing.<br>
