Until now the udev script for blktap devices needs to decide if to
signal success or failure to xend. As this script runs completely
independent of blktapctrl and tapdisk/ioemu which do the real work,
the udev script can't even theoretically know if tapdisk is happy.
This patch removes the udev script and replaces its checks by new
ones in libblktap.

Connections to ioemu have single_handler set, so they are closed as
soon as all images of a certain type are closed. This is wrong with
ioemu: All images that belong to the same domain are handled by the
same backend process (usually qemu-dm, but also tapdisk-ioemu for
domains without device model), regardless of the image type.
This patch checks for the same-domain condition for ioemu connections.

Currently all disk types that are supported are defined in a header
file private to blktapctrl and tapdisk. When restoring ioemu as a
backend for blktap these constants are needed by ioemu, so move them
to a more public header file.

This patch adds support for specifying the backend (tapdisk or ioemu)
to blktapctrl. Images can be specified e.g. as tap:tapdisk:aio,
tap:ioemu:qcow2 or tap:vmdk. When omitting the backend, a default is
chosen based on the image type (currently always tapdisk because ioemu
as a backend is broken until a follow-up patch series against qemu-xen
is applied)

This is a corrected version of a patch commited as c/s 19250 and
reverted by c/s 19314. Thanks to "trap sigerr ERR" in
xen-hotplug-common.sh the xen-hotplug-cleanup would exit when reading
/local/domain/ID/vm fails thus skipping all the xenstore-rm lines in
the rest of the script.
Change deviceDestroy behavior to remove /vm/UUID/device/...
path only when force was used (as it already does so for both frontend
and backend) and do the removing from xen-hotplug-cleanup script when
we are sure the device is really not attached to the guest any more.

The code was attempting to use the domain's current number of pages
(info.nr_pages) as a maximum index. We then walk the memory map and
can easily over-write past the end of the nr_pages-sized array, if the
domain has more pages mapped in than earlier (live dump). Restrict
ourselves to the current number of pages.
Also fix the dump core method in xend to actually implement the crash
and live options. In particular this means that xend clients other
than xm now get non-live dumps by default.

The Solaris curses library has a broken timeout() function: after a
first timeout() call with a positive value for an argument, subsequent
calls will fail to reset it. So, getch() always times out, confusing
the pygrub timer in the main loop. Add an extra check to avoid exiting
prematurely.

Make sure that tty semantics are active for Solaris ptys, or if they
aren't (and not needed) to not do tcget/setattr on the filedescriptor
in Python code.
Also work around a bug in the Solaris ptm streams driver, which will
cause a write error on the master side of a pty (because of e.g. a
missing slave) to persist forever.

In the case of a host OS without lsscsi command, the following
error message is recorded into xend-debug.log when xend is started.
The error message is recorded once certainly. If SCSI devices are
connected to the host OS, it is recorded to the number of SCSI
devices.
sh: lsscsi: command not found

In the stubdom case you can now specify sdl=1 and vnc=1 (again, both
can be selected at the same time) in the vfb configuration.
So instead of:
vfb = [ 'type=vnc' ]
now you have:
vfb = [ 'vnc=1,sdl=1' ]
the former configuration option is deprecated but still supported for
backward compatibility.

D3hot state in some PCI devices causes the failure of domain
creation/destruction.
The default is "pci_power_mgmt=3D0" which disables the guest OS from
managing D-states because it would be better to avoid the trouble than
advantage of low power consumption.

This patch adds a per-domain flag to specify whether a domain will be
S3 integrity protected when Xen is launched using tboot/TXT.
The tools now support an integer domain configuration parameter called
's3_integrity', which defaults to 1, to enable S3 integrity protection.
The struct arch_domain structure has been extended to have an
's3_integrity' field that represents this setting.
