Changeset 10923:8bdfe8dd9c2b

---------------------------

rename System.{hh,cc} to RubySystem.{hh,cc}
The eventual aim of this change is to pass RubySystem pointers through to objects generated from the SLICC protocol code.
Because some of these objects need to dereference their RubySystem pointers, they need access to the System.hh header file.
In src/mem/ruby/SConscript, the MakeInclude function creates single-line header files in the build directory that do nothing except include the corresponding header file from the source tree.
However, SLICC also generates a list of header files from its symbol table, and writes it to mem/protocol/Types.hh in the build directory. This code assumes that the header file name is the same as the class name.
The end result of this is the many of the generated slicc files try to include RubySystem.hh, when the file they really need is System.hh. The path of least resistence is just to rename System.hh to RubySystem.hh.
