[PATCH v3 0/3] nbd: MULTI_CONN for shared writable exports

[Eric Blake]

v2 was here:
https://lists.gnu.org/archive/html/qemu-devel/2022-02/msg03314.html

Since then:
- expose the knob through 'qemu-nbd -m on|off|auto'
- reuse QAPI OnOffAuto type instead of rolling my own
- rewrite the iotest from bash into python (thanks: Nir, Vladimir)
- split out easy preliminary fixes (patches 1 and 2 are new)

Given that this is a new feature, it probably needs to be 7.1 material.
