Made kern a switching header file directory.
SConstruct: Put the code to make a switching header directory into a function so they are easy to make. src/arch/SConscript: Replace switching header code with the new function call. src/kern/SConscript: Created a new switching header directory in kern, and moved the declaration of some source files here. --HG-- rename : src/kern/kernel_stats.cc => src/kern/base_kernel_stats.cc rename : src/kern/kernel_stats.hh => src/kern/base_kernel_stats.hh extra : convert_revision : 98f5320a5ade567c3e4f67fef123dfb0c5122545
