Subject: [PATCH 00/16] constify copied structure

Make const static structures that are just copied into other structures.

The semantic patch that detects the opportunity for this change is as
follows: (http://coccinelle.lip6.fr/)

<smpl>
@r disable optional_qualifier@
identifier i,j;
position p;
@@
static struct i j@p = { ... };

@upd@
position p1;
identifier r.j;
expression e;
@@
e = j@p1

@ref@
position p2 != {r.p,upd.p1};
identifier r.j;
@@
j@p2

@script:ocaml depends on upd && !ref@
i << r.i;
j << r.j;
p << r.p;
@@
if j = (List.hd p).current_element
then Coccilib.print_main i p
</smpl>
