`build_assert` relies on the compiler to optimize out its error path.
Functions using it with its arguments must thus always be inlined,
otherwise the error path of `build_assert` might not be optimized out,
triggering a build error.

This patch adds support for non-threaded IRQs and handlers through
irq::Registration and the irq::Handler trait.
Registering an irq is dependent upon having a IrqRequest that was
previously allocated by a given device. This will be introduced in
subsequent patches.

[ Remove expect(dead_code) from Flags::into_inner(), add
expect(dead_code) to IrqRequest::new(), fix intra-doc links. - Danilo ]

Manipulating IRQ flags (i.e.: IRQF_*) will soon be necessary, specially to
register IRQ handlers through bindings::request_irq().
Add a kernel::irq::Flags for that purpose.
