SIGINT causes ugly unhandled exceptions in log and batch mode, which we
prevent by catching the exceptions accordingly.

The previous version was catching all exceptions, including SIGINT.
We only want to catch the curses exceptions here.

When running kvm_stat in interactive mode, the cursor appears at the lower
left corner, which looks a bit distracting.
This patch hides the cursor by turning it invisible.

A lot of the code works with the perf events about which only sparse
documentation was available until 2012. Having that information now,
we can clarify what is done in the code.

Having stats for single VMs can help to determine the problem of a VM
without the need of running other tools like perf.
The tracepoints already allowed pid level monitoring, but kvm_stat
didn't have support for it till now. Support for the newly implemented
debugfs vm monitoring was also implemented.

if ARCH.exit_reasons:
AttributeError: 'ArchPPC' object has no attribute 'exit_reasons'
This is because, its trying to access a non-defined attribute.
Also, the IOCTL number of RESET is incorrect for powerpc. The correct
number has been added.

This tool displays kvm vm exit statistics to ease vm monitoring. It
takes its data from the kvm debugfs files or the vm tracepoints and
outputs them as a curses ui or simple text.
It was moved from qemu, as it is dependent on the kernel whereas qemu
works with a large number of kernel versions, some of which may break
the script.
