style: [patch 1/22] use /r/3648/ to reorganize includes

style: fix missing spaces in control statements

Result of running 'hg m5style --skip-all --fix-control -a'.

Ruby: Convert CacheRequestType to RubyRequestType
This patch converts CacheRequestType to RubyRequestType so that both the
protocol dependent and independent code makes use of the same request type.

Ruby: Convert AccessModeType to RubyAccessMode
This patch converts AccessModeType to RubyAccessMode so that both the
protocol dependent and independent code uses the same access mode.

ruby: get rid of the Map class

ruby: get "using namespace" out of headers
In addition to obvious changes, this required a slight change to the slicc
grammar to allow types with :: in them. Otherwise slicc barfs on std::string
which we need for the headers that slicc generates.

ruby: continue style pass

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.

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.
