Based-on: <20200924152717.287415-1-kwolf@redhat.com>
(block/export: Add infrastructure and QAPI for block exports)

Also available at:
https://repo.or.cz/qemu/ericb.git/shortlog/refs/tags/nbd-alloc-depth-v2

Since then:
- rebase on Kevin's work
- add new patch to fix qemu-nbd SIGINT (conflicts with Stefan's work,
we can either rebase his on mine or drop mine if his goes in first)
- split out fix for handling NUL bytes from client [Vladimir]
- further cleanups of query parsing [Vladimir]
- more documentation of how we could also expose actual depth in
remaining bits of the context reply [Rich]
