Augment watchdog_setup() to be able to possibly return an error, and introduce
watchdog_enabled() as a better alternative to knowing the architectures
internal details.
This patch does not change the x86 implementaion, beyond making it compile.
For header files, some includes of xen/nmi.h were only for the watchdog
functions, so are replaced rather than adding an extra include of
xen/watchdog.h

Introduce a command parameter to set the watchtog timeout. Manually
specifying "watchdog_timeout=<seconds>" on the command line will also
turn the watchdog on. For consistency, move opt_watchdog into nmi.c
along with opt_watchdog_timeout.

This patch adds core and generic x86 support code to enable Xen to
pass NMI's to a dedicated NMI callback in DOM0 instead of raising a
VIRQ.
Introduces the nmi_op hypercall to allow DOM0 to (un)register the NMI
handler.
