Enable ioeventfd for virtio-serial devices by default. Commit
25db9ebe15 lists the benefits of using
ioeventfd.
Copying a file from guest to host over a virtio-serial channel didn't
show much difference in time or io_exit rate.

Port 0 is reserved for virtconsole devices for backward compatibility
with the old -virtioconsole (from qemu 0.12) device type.
libvirt prior to commit 8e28c5d40200b4c5d483bd585d237b9d870372e5 used
port 0 for generic ports. libvirt will no longer do that, but disallow
instantiating generic ports at id 0 from qemu as well.

Index 75 is one too large for AR_TABLE[75], DR_TABLE[75].
This error was reported by cppcheck.
hw/fmopl.c:600: error: Buffer access out-of-bounds: OPL.AR_TABLE
hw/fmopl.c:601: error: Buffer access out-of-bounds: OPL.DR_TABLE
Fix this by limiting the access to the allowed range.
MultiArcadeMachineEmulator has newer versions of fmopl,
but using these requires more efforts.

Before commit 63ffb564dc, states for
floppy drives were calculated in fdc.c:fd_revalidate(). There it is
also considered whether a disk is inserted or not. The commit didn't copy
the logic completely to pc.c, which caused a regression.
Fix by adding the same check also to pc.c.

First, sysbus_init_irq shan't be called on on-stack variables. Indeed,
it only stores a passed pointer in qdev and the stored irq is later
populated, so we get a nice write-to-stack bug.
Second, irq for pxa27x should probably be handled in a more gentler way,
as we should check if we have events to raise this irq.

This patch add support for a system control block. It is supposed to
act as helper for the emulated program. E.g. shutting down the VM or
printing test results. This model is intended for testing purposes only and
doesn't fit to any real hardware. Therefore, it is not added to any board
by default. Instead a user has to add it explicitly with the '-device'
commandline parameter.

A pointer to a size_t variable was passed as the void * pointer to
lduw_p() in virtio_net_receive(). Instead of acting on the 16-bit value
this caused failure on big-endian hosts.
Avoid this issue in the future by using stw_p() instead. In general we
should use ld*_p() for loading from target memory and st*_p() for
storing to target memory anyway, not the other way around.
Also tighten up a correct use of lduw_p() when stw_p() should be used
instead in virtio_net_get_config().
