Other modules that depends on it, can reuse includes on linking.
There some files formally not belonging any packages (lib directory), as workaround there temporary include_directories(cfile) on root of project. After migrating all modules this can be removed.
Most of the warnings were caused by uninitialized values. Some were in plug-ins that didn't have a break in a switch, causing the memory to be deleted twice.
Most of these warnings are due to the use of NULL instead of 0 or NULL instead of '\0'.
Some are macro redefinitions. None of them are pointer storage related. Those will be
in another PR.
