powerpc: add usermode support
The biggest difficulty for user mode is MMU support. Otherwise it is
a simple matter of setting and clearing MSR[PR] with rfid and sc
respectively.
Some common harness operations will fail in usermode, so some workarounds
are reqiured (e.g., puts() can't be used directly).
A usermode privileged instruction interrupt test is added.

powerpc: add SMP and IPI support
powerpc SMP support is very primitive and does not set up a first-class
runtime environment for secondary CPUs.
This reworks SMP support, and provides a complete C and harness
environment for the secondaries, including interrupt handling, as well
as IPI support.

lib/powerpc: Add function to start secondary threads
Add the lib/powerpc/smp.c file and associated header files as a place
to implement generic smp functionality for inclusion in tests.
Add functions start_all_cpus(), start_cpu() and start_thread() to start
all stopped threads of all cpus, all stopped threads of a single cpu or a
single stopped thread of a guest at a given execution location,
respectively.
