Drop a bunch of _really_ old dead code (ASSERT() buried behind a DEBUG
macro that probably hasn't been enabled in 15+ years), clean up the bizarre
and confusing "dest_map" pointer that gets passed all of the place but is
only actually used for in-kernel RTC emulation, and the bury almost all of
ioapic.h behind CONFIG_KVM_IOAPIC=y.

I'm not entirely sure why I started poking at this.  I think I got mad at
the dest_map code, and then things snowballed...

  KVM: x86: Drop ASSERT()s on APIC/vCPU being non-NULL
  KVM: x86: Drop guest/user-triggerable asserts on IRR/ISR vectors
  KVM: x86: Drop ASSERT() on I/O APIC EOIs being only for LEVEL_to
    WARN_ON_ONCE
  KVM: x86: Drop guest-triggerable ASSERT()s on I/O APIC access
    alignment
