virt-sanlock-cleanup.8 has static contents (no dependency on
configure), but is generated by pod2man (a perl dependency that
maintainers must have, but which ordinary tarball users need
not have).  Therefore, ensure that it is always part of the
tarball, even though it is only conditionally installed.

This is similar to commit 6db98a2d, but made simpler by the fact
that the .8 page is static content.

* tools/Makefile.am (EXTRA_DIST): Add virt-sanlock-cleanup.8.

The current sanlock plugin requires a central management
application to manually add <lease> elements to each guest,
to protect resources that are assigned to it (eg writable
disks). This makes the sanlock plugin useless for usage
in more ad hoc deployment environments where there is no
central authority to associate disks with leases.

This patch adds a mode where the sanlock plugin will
automatically create leases for each assigned read-write
disk, using a md5 checksum of the fully qualified disk
path. This can work pretty well if guests are using
stable disk paths for block devices eg /dev/disk/by-path/XXXX
symlinks, or if all hosts have NFS volumes mounted in
a consistent pattern.

The plugin will create one lockspace for managing disks
with filename /var/lib/libvirt/sanlock/__LIBVIRT__DISKS__.
For each VM disks, there will be another file to hold
a lease /var/lib/libvirt/sanlock/5903e5d25e087e60a20fe4566fab41fd
Each VM disk lease is usually 1 MB in size. The script
virt-sanlock-cleanup should be run periodically to remove
unused lease files from the lockspace directory.

To make use of this capability the admin will need to do
several tasks:

 - Mount an NFS volume (or other shared filesystem)
   on /var/lib/libvirt/sanlock
 - Configure 'host_id' in /etc/libvirt/qemu-sanlock.conf
   with a unique value for each host with the same NFS
   mount
 - Toggle the 'auto_disk_leases' parameter in qemu-sanlock.conf

Technically the first step can be skipped, in which case
sanlock will only protect against 2 vms on the same host
using the same disk (or the same VM being started twice
due to error by libvirt).

We weren't using the @FOO@ notation for a Makefile substitution,
but instead for a sed rule, so using [@]FOO@ instead avoids the
need to exempt this syntax check.

Right now, 'man libvirtd' includes information that depends on
configure results, so it must be generated on the fly and live
in $(builddir); however, requiring pod2man on all end user
machines is overkill.  Meanwhile, 'man virsh' doesn't mention
any configure results, so it can be built at 'make dist' time.
If that situation changes in the future, we can generate virsh.1
in the same way that we generate libvirtd.8.

Last time I ran ./autobuild.sh was on F13; and upgrading to F14
exposed these leftovers due to a newer gcov than what was in the stale

tools/console.c depends on daemon/event.h.

This re-writes the 'virsh console' command so that it uses
the new streams API. This lets it run remotely and/or as a
non-root user. This requires that virsh be linked against
the simple event loop from libvirtd in daemon/event.c
As an added bonus, it can now connect to any console device,
not just the first one.

* tools/Makefile.am: Link to event.c
* tools/console.c, tools/console.h: Rewrite to use the
  virDomainOpenConsole() APIs with streams
* tools/virsh.c: Support choosing the console name

Now that the virsh parsing has been revamped, we can
implement qemu-monitor-command.  This is basically the same
as it was in previous iterations, but has now been tested to
work both with the plain text monitor and the QMP monitor.

Since libvirt-guests init script and its configuration do not require
libvirtd to be running/installed, it was a bad idea to put them into
daemon directory. libvirt.spec even includes these files in
libvirt-client subpackage, which may result in build failure for
client-only builds when the whole daemon directory is just skipped.

Matthias noted that the line:
virt_aa_helper_LDFLAGS = $(WARN_CFLAGS)
looks inconsistent, so I did an audit.

Currently, the set of compiler warning flags passed to gcc as $CC are
equally permitted as the set of linker flags passed to gcc as $LD, so
there was no problem with that usage.  But if we ever get in a
situation where $CC and $LD treat particular flags differently, using
the right variable form will make it easier.

In the process, I spotted a couple of typos that were omitting useful
flags, as well as specifying a -l under the wrong variable.
