un-tokenize savers

un-tokenize savers

* Un-tokenize all savers again. We can't simply tokenize around vidsw[]
  that easily because the saver functions are called from the console
  paths, too (cnputc, ...)

* Regarding vidsw we'll eventually have to find a different solution to
  lock it up. The current approach can't work.
