This series is to address the type matching problem in Coccinelle.

Patch 1/3 is for aligning the C and Cocci AST so that
pointer to const pointer and its variants can be matched.

Patch 2/3 reflects the pretty printing changes made in 
1/3 in the ptrconstptr test case. A space is added between
the * and const.

Patch 3/3 consists of a test case for matching a pointer to
const pointer and its variants.

Changes in v5:
- Remove unnecessary parantheses and return of unit in Patch 1/3.
- Have the test case in Patch 3/3 conform more closely with the
  Linux kernel coding style.

Changes in v4:
- Fix coding style w/r/t placement of comment with List.iter and
  the qualifier printing function.

Changes in v3:
- Add a space between the * and qualifier in Patch 1/3.
- Add Patch 2/3 to add a space between * and const in the test
  case ptrconstptr.

Changes in v2:
- Change body and subject of Patch 2/2 as per suggestion of Markus
