like we have on other platforms. Move savectx() to <machine/pcb.h>. A lot of files got these MD prototypes through the indirect inclusion of <machine/cpu.h> and now need to include <machine/md_var.h>. The number of which is unexpectedly large... osf1_misc.c especially is tricky because szsigcode is redefined in one of the osf1 header files. Reordering of the include files was needed. linprocfs.c now needs an explicit extern declaration. Tested with: LINT
