SV: SV: [Cocci] adding #include's

I am not sure there is a simple solution. A workaround is to use the Python API and
the cocci.include_match(False) feature.

In the first rule, you match on a function/variable declaration and keep its position.

@first_fct@
type T;
identifier f;
position p;
@@

T f at p (...) {...}

@first_var@
type T;
identifier v;
position p;
@@

T v at p;

These rules will match any fct/var declaration but you could filter with python to select
only the first one, using p[0].line, and discard the other ones with include_match(False).

To select only the first one, you will need a global variable in Python. It can be declared and initial to 0 in the @initialize:python@ section at the very beginning of the cocci file.

Finally, write two cocci rules to add the #include either before the variable declaration
or the function declaration and ensure that the position is the same.

You are welcome to post your complete solution in our Wiki.

Don't hesitate if something is not clear.
