I noticed that directorty structure of hphp/system was a bit scattered, so I consolidated things to reduce the total number of folders and to put related things together with each other. This diff moves the contents of "hphp/system/classes_hhvm" into "hphp/system", it moves the contents of "hphp/system/lib" into "hphp/system", moves "hphp/idl" to "hphp/system/idl", and moves the contents of "hphp/system/globals" into "hphp/system/idl".
