This is a reworked version of the NMI watchdog fixes, taking the
discussion with Sheng into account. There are two further (minor) issues
I found in the APIC emulation at this chance, but those can be handled
separately.

This patch refactors the NMI watchdog delivery patch, consolidating
tests and providing a proper API for delivering watchdog events.
An included micro-optimization is to check only for apic_hw_enabled in
kvm_apic_local_deliver (the test for LVT mask is covering the
soft-disabled case already).

As suggested by Avi, this patch introduces a counter of VCPUs that have
LVT0 set to NMI mode. Only if the counter > 0, we push the PIT ticks via
all LAPIC LVT0 lines to enable NMI watchdog support.

Oh... Please ignore my comments on the other patch for software enable bit.
:) (But I think this kind of optimization is reducing the readability a
little as well... It's easy to get curious about why only hardware enable is
OK)
Others seems OK to me.
