The 3rd parameter of kvm_apic_match_dest() is the irq shorthand,
rather than the irq delivery mode.

kvm_apic_match_dest() is declared in both ioapic.h and lapic.h.
Remove the declaration in ioapic.h.
kvm_apic_compare_prio() is declared in ioapic.h but defined in
lapic.c. Move the declaration to lapic.h.
kvm_irq_delivery_to_apic() is declared in ioapic.h but defined in
irq_comm.c. Move the declaration to irq.h.
hyperv.c needs to use kvm_irq_delivery_to_apic(). Include irq.h in
hyperv.c.

We were using either APIC_DEST_PHYSICAL|APIC_DEST_LOGICAL or 0|1 to
fill in kvm_lapic_irq.dest_mode. It's fine only because in most cases
when we check against dest_mode it's against APIC_DEST_PHYSICAL (which
equals to 0). However, that's not consistent. We'll have problem
when we want to start checking against APIC_DEST_LOGICAL, which does
not equals to 1.
This patch firstly introduces kvm_lapic_irq_dest_mode() helper to take
any boolean of destination mode and return the APIC_DEST_* macro.
Then, it replaces the 0|1 settings of irq.dest_mode with the helper.

We have both APIC_SHORT_MASK and KVM_APIC_SHORT_MASK defined for the
shorthand mask. Similarly, we have both APIC_DEST_MASK and
KVM_APIC_DEST_MASK defined for the destination mode mask.
Drop the KVM_APIC_* macros and replace the only user of them to use
the APIC_DEST_* macros instead. At the meantime, move APIC_SHORT_MASK
and APIC_DEST_MASK from lapic.c to lapic.h.

Callers of kvm_apic_match_dest() should always pass in APIC_DEST_*
macros for either dest_mode and short_hand parameters. Fix up all the
callers of kvm_apic_match_dest() that are not following the rule.
Since at it, rename the parameter from short_hand to shorthand in
kvm_apic_match_dest(), as suggested by Vitaly.
