Jakub noticed[1] that, when using pin-based interrupts, the device will
unconditionally deasssert when any CQEs are acknowledged. However, the
pin should not be deasserted if other completion queues still holds
unacknowledged CQEs.
The bug is an artifact of commit ca247d3509 ("hw/block/nvme: fix
pin-based interrupt behavior") which fixed one bug but introduced
another. This is the third time someone tries to fix pin-based
interrupts (see commit 5e9aa92eb1 ("hw/block: Fix pin-based interrupt
behaviour of NVMe"))...
Third time's the charm, so fix it, again, by keeping track of how many
CQs have unacknowledged CQEs and only deassert when all are cleared.

Since all "multi aio" commands are now reimplemented to properly track

The word may in this sentence means that automatically transitioning
an implicitly opened zone to closed is completely optional.
Add a new parameter so that the user can control if this automatic
transitioning should be performed or not.
Being able to control this can help with verifying that e.g. a user-space

Some machines use floppy controllers via the SysBus interface,
and don't need to pull in all the SysBus code.
Extract the SysBus specific code to a new unit: fdc-sysbus.c,
and add a new Kconfig symbol: "FDC_SYSBUS".

Some machines use floppy controllers via the SysBus interface,
and don't need to pull in all the ISA code.
Extract the ISA specific code to a new unit: fdc-isa.c, and
add a new Kconfig symbol: "FDC_ISA".
This allows us to remove the FIXME from commit dd0ff8191a
("isa: express SuperIO dependencies with Kconfig").
