Hello reviewers,
These patches were originally created by Petr. The patches 3 and 4 were
originally one bigger patch but they are more easily reviewed split.
The patches 1 and 2 are code improvements.
Patch 3 adds a new struct called klp_shadow_type that combines the id, ctor and
dtor of a shadow variable. This patch is needed by patch 4.
Patch 4 adds the garbage collection.
Thanks for reviewing!
