spice: fix display initialization

Spice has two display interface implementations:  One integrated into
the qxl graphics card, and one generic which can operate with every
qemu-emulated graphics card.

The generic one is activated in case spice is used without qxl.  The
logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes
unnoticed.  Fix that by adding a check in the spice interface
registration so we'll notice the qxl card no matter how it is created.

hcd-ohci: add dma error handling

Current hcd-ohci does not handle DMA errors. However they may happen
so here we introduce simple error handling.

On such errors, a typical OHCI will stop operating, signal the guest
about the error by sending "UnrecoverableError Event", set itself into
error state and set "Detected Parity Error" in its PCI config space
to signal that it got an error and so does the patch.

This also adds ohci_die() call to ohci_bus_start() to handle possible
failure of qemu_new_timer_ns().

s390x/ioinst: Throw addressing exception when memory_map failed

So far, the IO instructions were throwing specification exceptions when
there was a problem with accessing the memory. However, the better way
is to throw an addressing exception instead.

Consolidated the setting of the condition code in kvm_handle_css_inst().
For the (unhandled) instructions EQBS and SQBS, we have to return
an operation exception instead of cc3. Also removed the is_ioinst()
function to avoid decoding the opcode twice.

With this patch dump-guest-memory on s390 produces an ELF formatted,

chardev: fix CHR_EVENT_OPENED events for mux chardevs

As of bd5c51ee6c4f1c79cae5ad2516d711a27b4ea8ec, chardevs no longer use
bottom-halves to issue CHR_EVENT_OPENED events. To maintain past
semantics, we instead defer the CHR_EVENT_OPENED events toward the end
of chardev initialization.

For muxes, this isn't good enough, since a range of FEs must be able
to attach to the mux prior to any CHR_EVENT_OPENED being issued, else
each FE will immediately print it's initial output (prompts, banners,
etc.) just prior to us switching to the next FE as part of
initialization.

The is new and confusing behavior for users, as they'll see output for
things like the HMP monitor, even though their the current mux focus
may be a guest serial port with potentially no output.

We fix this by further deferring CHR_EVENT_OPENED events for FEs
associated with muxes until after machine init by flagging mux chardevs
with 'explicit_be_open', which suppresses emission of CHR_EVENT_OPENED
events until we explicitly set the mux as opened later.

Currently, we must defer till after machine init since we potentially
associate FEs with muxes as part of realize (for instance,
serial_isa_realizefn).
