Devices use irqfd to inject interrupts, we listen to them in the main
thread and activate userspace pic/ioapic accordingly.

This change implements MSI routing and injection, so that service_irq
can actually inject an interrupt into guest.

Interrupt polarity is ignored by kvm since 3.15, and the irqfd interface
does not support polarity. We should not consider polarity either.

Before the new borrow checker in the 2018 edition, we sometimes used to
have to manually insert curly braced blocks to limit the scope of
borrows. These are no longer needed.

Macros were previously imported through `#[macro_use] extern crate`,
which is basically a glob import of all macros from the crate. As of
2018 edition of Rust, `extern crate` is no longer required and macros
are imported individually like any other item from a dependency. This CL
fills in all the appropriate macro imports that will allow us to remove
our use of `extern crate` in a subsequent CL.

Separated out of CL:1513058 to make it possible to land parts
individually while the affected crate has no other significant CLs
pending. This avoids repeatedly introducing non-textual conflicts with
new code that adds `use` statements.

This change implements service_irq, end_of_interrupt, and just enough to
add some basic tests for those.
Still TODO: Interrupt routing (and tests for that) and tests that
require additional functionality.

This CL adds some necessary constants and types, as well as a few
skeleton function declarations, for an IOAPIC device.
I'm sending this CL first in the interest of minimizing CL size and
making future CLs easier to review.
