o Minor features (developer tools):
    - Add some scripts in "scripts/coccinelle" to invoke the Coccinelle
      semantic patching tool with the correct flags.  These flags are fairly
      easy to forget, and these scripts should help us use Coccinelle more
      effectively in the future. Closes ticket 31705.

  o Code simplification and refactoring:
    - Fix some parts of our code that were difficult for Coccinelle to parse.
      Related to ticket 31705.
