Add kernel profiling through sampling
* NEWS: Advertise feature.
* configfrac.ac (--enable-kernsample): Add option.
* kern/pc_sample.h (take_pc_sample): Add usermode and pc parameter.
(take_pc_sample_macro): Take usermode and pc parameters, pass as such to
take_pc_sample.
* kern/pc_sample.c (take_pc_sample): Use pc parameter when usermode is 1.
* kern/mach_clock.c (clock_interrupt): Add pc parameter. Pass usermode and
pc to take_pc_sample_macro call.
* i386/i386/hardclock.c (hardclock): Pass regs->eip to clock_interrupt call
on normal interrupts, NULL on interrupt interrupt.
* vm/vm_fault.c (vm_fault_cleanup): Set usermode to 1 and pc to NULL in
take_pc_sample_macro call.
