blymn 8387760ed1 Rototill of the verified exec functionality.
* We now use hash tables instead of a list to store the in kernel
    fingerprints.
  * Fingerprint methods handling has been made more flexible, it is now
    even simpler to add new methods.
  * the loader no longer passes in magic numbers representing the
    fingerprint method so veriexecctl is not longer kernel specific.
  * fingerprint methods can be tailored out using options in the kernel
    config file.
  * more fingerprint methods added - rmd160, sha256/384/512
  * veriexecctl can now report the fingerprint methods supported by the
    running kernel.
  * regularised the naming of some portions of veriexec.
