Colin Walters 305db981d4 Add Coccinelle usage: one for blacklisting, one for patch collection 
This is inspired by the [Coccinelle](http://coccinelle.lip6.fr/) usage
in systemd.  I also took it a bit further and added infrastructure
to have spatches which should never apply.  This acts as a blacklist.

The reason to do the latter is that coccinelle is *way* more powerful than the
regular expresssions we have in `make syntax-check`.

I started with blacklisting `g_error_free()` directly. The reason that's bad is
it leaves a dangling pointer.

Closes: #754

Raw Blame History

This is a directory of semantic patches to apply with coccinelle, like the collection in systemd: 29f3265584/coccinelle

See also the tests/coccinelle directory which has spatches which detect errors.
