PCI devices will require interrupts, allow this by passing a vector of
IRQs to the mptable so the guest kernel can find the IRQs.

Combine GPU buffer allocation with the system resource allocator making
life easier as only one allocator needs to get passed to the execute
function.

Allow IRQs to be assigned before creating device manager.
For PCI, we need to add devices with interrupts before MMIO setup. Add
the ability to tell the architecture device manager about IRQs that we
have stolen.
There was only one function in device_manager and all of its state is
now delegated to the resource allocator, remove it.

This fixes an issue on kevin where if we start on a little core, the
kernel doesn't like the generic ARMv8 target cpu type for some reason. To
fix this we must query the preferred type from the vm device first and
supply that to the vcpu init ioctl.
We need to change the signature of the configure_vcpu method to pass
in the vm object even though we aren't using it on x86.

This creates a trait that different architectures can implement to
support running Linux VMs.
In the implementation on X86 we remove some error and return errors
from lower-level modules as appropriate. These modules now implement
the Error trait so we can get meaningful descriptions without an extra
error from the calling function. This still keeps all the ifdefs in
linux.rs for now until we have another implementation to use for ARM.
