    sys/powerpc/powerpc  copyinout.c machdep.c vm_machdep.c 
  Log:
  Kernel changes for libthr (and probably libpthread).
  
  include/ucontext.h
   - remove trapframe and switch over to 'generic' description of machine
     state. Include version field to help with future modifications.
     Include floating point and altivec state, and hopefully align
     correctly
  
  powerpc/copyinout.c
   - fill out casuptr() sync primitive, required by kern_umtx.c
  
  powerpc/machdep.c
   - shifted proc0/thread0/pcpu setup to before cninit, since
     syscons -> make_dev -> devlock requires a valid curthread
   - implemented get_mcontext/set_mcontext
   - recast sendsig/sigreturn to use get/set_mcontext and new
     ucontext struct. floating point now saved
   - TODO: save/restore altivec state
  
  powerpc/vm_machdep.c
   - implemented cpu_thread_setup/cpu_set_upcall/cpu_set_upcall_kse
   - eliminated trailing whitespace
