Kernel Debug via gdbstub

- There was some discussion about improving debug experience with
kernel debugging
- for example while in KVM a single-step usually goes to the
exception table
- in TCG this isn't always the case (maybe time accounting is
better?)
- follow-up on x86 and kgdb experience :todo
- worth creating a STORY for this work? :todo
