[PATCH 00/20] Const fixes

[Zdenek Kabelac <zkabelac@redhat.com>]

Primary reason for this patchset is to make stronger
const limitation around config_tree handling.
So we can be sure where this tree could be modified.
It also cleanup quite a few hidden const warning
(-Wbad-function-cast -Wcast-qual)

Patch is extended with few more minor patches gathers
from my tree which should be easy to review. Some of them
are probably some minor bugs in the code so it's worth to
check them in.
