When migrating a host with with a spice agent running the mouse becomes
non operational after the migration due to the agent state being
inconsistent between the guest and the client.
After migration the spicevmc backend on the destination has never been notified
of the (non 0) guest_connected state. Virtio-serial holds this state
information and migrates it, this patch properly propagates this information
to virtio-console and through that to interested chardev backends.

Most frontends can't really determine if the guest actually has the frontend
side open. So lets automatically generate fe_open / fe_close as soon as a
frontend becomes ready (as signalled by calling qemu_chr_add_handlers) /
becomes non ready (as signalled by setting all handlers to NULL).
And allow frontends which can actually determine if the guest is listening to
opt-out of this.

Fix the awkward API of mangling the caller specified PCIe type and
just provide an interface to initialize an endpoint device. This
will pick either a regular endpoint or integrated endpoint based on
the bus and return pcie_cap_init to doing exactly what is asked.

Windows will fail to start drivers for devices with an Endpoint type
PCIe capability attached to a Root Complex (code 10 - Device cannot
start). The proper type for such a device is Root Complex Integrated
Endpoint. Devices don't care which they are, so do this conversion
automatically.
This allows the Windows driver to load for nec-usb-xhci when attached
to pcie.0 of a q35 machine.

A zero size ROM file is invalid and should produce a warning.
Attempting to use a zero size file ends up hitting an assertion
qemu_ram_set_idstr() because RAMBlocks with duplicate addresses are
allocated - due to zero size the allocator doesn't increment the next
available RAMBlock offset.
Also convert __FUNCTION__ to __func__ while we're touching this code.
There are no other __FUNCTION__ instances in pci.c anymore.

For some reason we recurse to fire the INTx routing notifier for each
child of a bus, for each possible device of a bus. That means that if
we add a root port, the notifier gets called for that bridge 256
times. If we add an upstream switch behind that root port, 256^2. But
of course we need a downstream switch, 256^3. This starts to be
noticeable. Stop the insanity.

Each PCI Bridge has a set of implied VGA regions that are enabled when
the VGA bit is set in the bridge control register. This allows VGA
devices behind bridges. Unfortunately with VGA Enable, which we
formerly allowed but didn't back, comes along some required VGA
baggage. VGA Palette Snooping is required, along with VGA 16-bit
decoding. We don't yet have support for palette snooping.
We also don't have support for 10-bit VGA aliases, the default mode, but
we enable the register, even on root ports, to avoid confusing guests.
Fortunately there's likely nothing from this century that requires these
features, so the missing bits are noted with TODOs.

non-irqfd setups are currently broken with vhost:
we start up masked and nothing unmasks the interrupts.
Fix by using mask notifiers, same as the irqfd path.
Sharing irqchip/non irqchip code is always a good thing,
in this case it will help non irqchip benefit
from backend masking optimization.
