Subject: ruby: Import ruby and slicc from GEMS

We eventually plan to replace the m5 cache hierarchy with the GEMS
hierarchy, but for now we will make both live alongside eachother.

Subject: ruby: Make ruby #includes use full paths to the files they're
 including. This basically means changing all #include statements and changing
 autogenerated code so that it generates the correct paths.  Because slicc
 generates #includes, I had to hard code the include paths to mem/protocol.
