Currently if you redirect the output from "lkvm run" to a file then
term_init() will fail, because it can't call the terminal ioctls.
So check if stdin and stdout are ttys, if either is not then skip the
rest of the terminal setup. Redirecting one but not the other is a
little odd, but does work.
Add perror() calls to a couple of exit paths, to ease debugging.
There are also two places where we print "Failed starting IPC thread",
but one is really an epoll failure, so make that obvious.

In xics_init() we set the maximum server to kvm->nrcpus, and then set
the nr_servers using maximum server + 1.
That is off by one, in the harmless direction.
Simplify it to just set nr_servers = kvm->nrcpus.

Currently list always returns 0, even if there was an error. Instead
have it accumulate any errors and return that.

The kernel can handle a missing timebase-frequency property much better

During the review process for the KVM ARM patches, the GIC device
registration was subjected to some minor renaming, so update kvm tool
appropriately.
