Make use of the new clock reset notifier to update the RTC whenever
rtc_clock is the host clock and that happens to jump backward. This
avoids that the RTC stalls for the period the host clock was set back.

This allows to pass additional information to the notifier callback
which is useful if sender and receiver do not share any other distinct

Will be used first for the clock reset notifier.

Old version looks like this in info qtree (last four lines):
dev: virtconsole, id ""
dev-prop: is_console = 1
dev-prop: nr = 0
dev-prop: chardev = <null>
dev-prop: name = <null>
dev-prop-int: id: 0
dev-prop-int: guest_connected: 1
dev-prop-int: host_connected: 0
dev-prop-int: throttled: 0
Indentation is off, and "dev-prop-int" suggests these are properties
you can configure with -device, which isn't the case. The other
buses' print_dev() callbacks don't do that. For instance, PCI's
output looks like this:
class Ethernet controller, addr 00:03.0, pci id 1af4:1000 (sub 1af4:0001)
bar 0: i/o at 0xffffffffffffffff [0x1e]
bar 1: mem at 0xffffffffffffffff [0xffe]
bar 6: mem at 0xffffffffffffffff [0xfffe]
Change virtser_bus_dev_print() to that style. Result:
dev: virtconsole, id ""
dev-prop: is_console = 1
dev-prop: nr = 0
dev-prop: chardev = <null>
dev-prop: name = <null>
port 0, guest on, host off, throttle off

The only way for chardev drivers to communicate an error was to return a NULL
pointer, which resulted in an error message that said _that_ something went
wrong, but not _why_.
This patch changes the interface to return 0/-errno and updates
qemu_chr_open_opts to use strerror to display a more helpful error message.

Serial and parallel devices created with -device are not reported in
the PIIX4 configuration space, and are hence not picked up by the DSDT.
This upsets Windows, which hides them altogether from the guest.
To avoid this, check at the end of machine initialization whether the
corresponding I/O ports have been registered. The new function in
ioport.c does this; this also requires a tweak to isa_unassign_ioport.
I left the comment in piix4_pm_initfn since the registers I moved do
seem to match the 82371AB datasheet. There are some quirks though.
We are setting this bit:
"Device 8 EIO Enable (EIO_EN_DEV8)—R/W. 1=Enable PCI access to the
device 8 enabled I/O ranges to be claimed by PIIX4 and forwarded
to the ISA/EIO bus. 0=Disable. The LPT_MON_EN must be set to enable
the decode."
but not LPT_MON_EN (bit 18 at 50h):
LPT Port Enable (LPT_MON_EN)—R/W. 1=Enable accesses to parallel
port address range (LPT_DEC_SEL) to generate a device 8 (parallel
port) decode event. 0=Disable.
We're also setting the LPT_DEC_SEL field (that's the 0x60 written to
63h) to 11, which means reserved, rather than to 01 (378h-37Fh).
Likewise we're not setting SA_MON_EN, SB_MON_EN (respectively bit 14
and bit 16 at address 50h) for the serial ports. However, we're setting
COMA_DEC_SEL and COMB_DEC_SEL correctly, unlike the corresponding register
for the parallel port.
All these fields are left as they are, since they are probably only
meant to be used in the DSDT.

Drop the open-coded MAC assignment from net_init_nic and replace it with
standard qemu_macaddr_default_if_unset which is also used by qdev. That
avoid creating colliding MACs when instantiating NICs via different
mechanisms.
This change requires to store the MAC as MACAddr in NICInfo, and the
remaining nd_table users need to be updated.
Based on suggestion by Peter Maydell.

'tag' is just an abstraction to identify the command
from the driver. So we should make that explicit by
replacing 'tag' with a driver-defined pointer 'hba_private'.
This saves the lookup for driver handling several commands
in parallel.
'tag' is still being kept for tracing purposes.

iov_to_buf() has an 'offset' parameter, iov_from_buf() hasn't.
This patch adds the missing parameter to iov_from_buf().
It also renames the 'offset' parameter to 'iov_off' to

A host chardev could close just before the guest sends some data to be
written. This will cause an -EPIPE error. This shouldn't be propagated
to virtio-serial-bus.
Ideally we should close the port once -EPIPE is received, but since the
chardev interface doesn't return such meaningful values to its users,
all we get is -1 for any kind of error. Just return 0 for now and wait
for chardevs to return better error messages to act better on the return
messages.

The new xen_console protocol changed the default xen_console output device
from whatever Qemu chose to whatever xenstore choses and "pty" as fallback.
This is not how Qemu works. It has its own serial redirection semantics. So
it xenstore doesn't contain information on what to do, Qemu is the place to
ask.

Since CS 21994 on xen-unstable.hg and CS
466608f3a32e1f9808acdf832a5843af37e5fcec on qemu-xen-unstable.git, few
changes have been introduced to the PV console xenstore protocol, as
described by the document docs/misc/console.txt under xen-unstable.hg.
From the Qemu point of view, very few modifications are needed to
correctly support the protocol: read from xenstore the "output" node
that tell us what the output of the PV console is going to be.
In case the output is a tty, write to xenstore the device name.
Changes in v2:
- fix error paths: free malloc'ed strings and close the xenstore
connection before returning;
- remove useless snprintf in xenstore_store_pv_console_info if i == 0.
Changes in v3:
- replace xs_daemon_open/xs_daemon_close with xs_open/xs_close.
Changes in v4:
- add a compatibility implementation of xs_open/xs_close.
Changes in v5:
- fix code style.

When disk is a cdrom and the drive is empty the "params" node in
xenstore might be missing completely: cope with it instead of
segfaulting.
Updated in v2:
- actually removed the strchr(blkdev->params, ':') that caused the
segfault;
- free all the allocated strings from xenstore before returning;
Updated in v3:
- set blkdev fields to NULL after free'ing them.

Register the vkbd backend even when running as device emulator for HVM
guests: it is useful because it doesn't need a frequent timer like usb.
Check whether the XenInput DisplayState has been set in the initialise
state, rather than the input state.
In case the DisplayState hasn't been set and there is no vfb for this
domain, then set the XenInput DisplayState to the default one.
Changed in v2:
- use qemu_free instead of free;

This bug was introduced in 94d3f98a3f3caddd7875f9a11776daeb84962a7b:
scsi_cancel_io was checking if some request was pending before trying
to cancel it, while scsi_req_cancel always cancels the request.
This may lead to a crash of Qemu due to dereferencing a NULL pointer,
as exhibited by NetBSD 5.1 installer on MIPS Magnum emulation.
