Alex Lin 19025d77ad Standardize directory names
Reorganized.  Created a new top level include directory that will hold all of Trick's header files. Moved all of the Trick headers to this directory.  Created a libexec directory that holds all of the executables that users don't need to execute directly.  Changed all of the executables remaining in bin to start with "trick-".  In the sim_services directories changed all source files to find the Trick headers in their new location.  Since all of the include files are gone in sim_services, removed the src directories as well, moving all of the source files up a level.  Moved the makefiles, docs, man, and other architecture independent files into a top level share directory.  Renamed lib_${TRICK_HOST_CPU} to lib64 or lib depending on the platform we're currently on.
