      [CTRACER]: Lots of improvements · ce9d7e11

      1. We now use relayfs
      2. ostra-cg is shipped and used in the Makefile
      3. README.ctracer has all the details
      
      I followed README.ctracer and the result, in my workstation, was this one:
      http://oops.ghostprotocols.net:81/acme/dwarves/callgraphs/acme_eating_his_dog_food/6.html
      
      I've started on the 6th page as it is more interesting, having tcp and netlink
      callchains, don't be disappointed by some pages having just one level of
      nesting, that is just the lack of containers and aliases (to follow tcp_sock,
      skb->sk, etc) from the OSTRA days, but it's getting there! :-)
      
      Ah, it is collecting all the base types in the specified struct by doing a
      struct "view", i.e. trimming the struct to have just members that are
      "reducible" to basic types (int, long, char, signed and unsigned), then
      reorganizing it with the code introduced in pahole --reorganize to get it to
      the best layout possible, reducing the size of the entry probe points trace
      entries.
      
      Updated rpms are available at the usual place:
