Anonymize image files

Summary: Teach CRIT to remove sensitive information from images

When reporting a BUG it may be not acceptable for the reporter to send us raw images, as they may contain sensitive data. Need to teach CRIT to "anonymise" images for publication.

List of data to shred:

  • Memory contents. For the sake of investigation, all the memory contents can be just removed. Only the sizes of pages*.img files are enough.
  • Paths to files. Here we should keep the paths relations to each other. The simplest way seem to be replacing file names with "random" (or sequential) strings, BUT (!) keeping an eye on making this mapping be 1:1. Note, that file paths may also sit in sk-unix.img.
  • Registers.
  • Process names. (But relations should be kept).
  • Contents of streams, i.e. pipe/fifo data, sk-queue, tcp-stream, tty data.
  • Ghost files.
  • Tarballs with tmpfs-s.
  • IP addresses in sk-inet-s, ip tool dumps and net*.img.
