Subject: [PATCH 0/4] delete useless variable

These patches delete declarations and initializations of variables that are
only assigned to constants but never used otherwise.

The complete semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
type T;
identifier i,i2;
position p;
@@

T i@p;
... 
i = i2

@@
type r.T;
identifier r.i;
constant c;
position p != r.p;
@@

-T i@p;
<... when != i
-i = c;
...>
// </smpl>
