remove static from klpp_ functions and add them to header file

[lhruska]

ccp always sets the LPed functions (klpp_ prefix) as static. The static keyword then be manually removed, and all those functions must also be added to the livepatch_xxx.h header file.
Automating this would save a lot of time and nerves.

This is already done by clang-extract, and unfortunately klp-ccp doesn't...

I know, but it can be fixed after running the klp-ccp by a few (hopefully) simple regexes. I will try to fix it.

Removing the static keyword from klpp functions would help us to match the expected behavior between cp and ce (we have issues about dead-code-elimination on ce and we spend quite sometime before realizing that removing the statis keyword would make it reproducible on ccp as well).
