Finish the control module, libltt and lttctl : netlink interface
Finish integrating lttctl with lttd.
fix lttctl signal waiting : use a flag.

-* TODO
+Add ltt_write_commit_counter call to genevent.
Add information in the buffer header : buffer size, etc etc...
-> this information is so small that we can repeat it. Makes flight recorder easier to decode.
-Add trace start structure to facility channel.
+Add trace start structure to buffer start header.
fix genevent : take no lock if num traces active is 0.


+* TODO
+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).
+fix structures alignment, array and sequences too. -> trace dynamic.
+add per facility alignment (inside structures).
+add control of alignment.
+add user space tracing.

* TODO (low priority)
Integrate header generation (genevent) in kernel build system.
