Ploop image consists of directory with two files: ploop image itself,
called root.hds and DiskDescriptor.xml that contains information about
ploop device: https://openvz.org/Ploop/format.
Such volume are difficult to manipulate in terms of existing volume types
because they are neither a single files nor a directory.
This patch introduces new volume type - ploop. This volume type is used
by ploop volume's exclusively.

Take setlocale/gettext error handling pattern from tools/virsh-*
and use it for all standalone binaries via a new shared
virGettextInitialize routine. The virsh* pattern differed slightly
from other callers. All users now consistently:

* Ignore setlocale errors. virsh has done this forever, presumably for
  good reason. This has been partially responsible for some bug reports:

Upcoming compression options for migration command patch
series hits current limit of 32 possible options for a command.
Lets take one step further and support 64 possible options.

And all it takes is moving from 32 bit integers to 64 bit ones.
The only less then trivial change i found is moving from
'ffs' to 'ffsl'.

Since we didn't opt to use one single event for device lifecycle for a
VM we are missing one last event if the device removal failed. This
event will be emitted once we asked to eject the device but for some
reason it is not possible.

virt-host-validate, just like virt-login-shell, doesn't make sense
on Windows, so we should avoid building it.

Make the tool optional and build it by default on all platforms
except Windows, erroring out if the user attempts to build it
anyway.

Instead of having separate handling for programs and man pages,
deal with both in the same place.

Simply checking whether the cgroup name appears somewhere inside
/proc/self/cgroup is enough most of the time, but there are some
corner cases that require a more mindful parsing.

Explicitly add Linux and BSD syms files for nss to EXTRA_DIST
instead of using the LIBVIRT_NSS_SYMBOL_FILE variable, because its value
will point to either Linux or BSD syms file, but we need to ship both.

The existing code is built on the assumption that no cgroup
name can appear as part of another cgroup name; moreover, cgroups
are expected to always be listed in a specific order.

If that's not the case, eg. 'cpuacct' is listed before 'cpu', the
algorithm fails to detect the cgroup mount point.

Rewrite it to get rid of such assumptions.

Instead of relying on substring search, tokenize the input
and process each CPU flag separately. This ensures CPU flag
detection will continue to work correctly even if we start
looking for CPU flags whose name might appear as part of
other CPU flags' names.

The result of processing is stored in a virBitmap, which
means we don't have to parse /proc/cpuinfo in its entirety
for each single CPU flag we want to check.

Moreover, use of the newly-introduced virHostValidateCPUFlag
enumeration ensures we don't go looking for random CPU flags
which might actually be simple typos.

There is a LIBVIRT_ADMIN_DEFAULT_URI environment variable
which is honored by virAdmConnectOpen and documented
in the virt-admin man page.

LIBVIRT_DEFAULT_ADMIN_URI is undocumented and this is its
only occurrence.

vshStrdup returns NULL without exiting on NULL input.

Postpone filling out the default connection in ctl->connname
after calling virshInit.

This allows printing help without a connection to the daemon.

When using the --start option, the show_count should not be set to
max_id as the --start <cpu> means we dont need those many initial cpu
stats. Hence, show_count should be adjusted accordingly.

Now that we have @flags we can support changing perf events just
in active or inactive configuration regardless of the other.
Previously, calling virDomainSetPerfEvents set events in both
active and inactive configuration at once. Even though we allow
users to set perf events that are to be enabled once domain is
started up. The virDomainGetPerfEvents API was flawed too. It
returned just runtime info.

If the cpu cgroup is not found when validating an host for
LXC support, virt-host-validate will suggest to enable the
CONFIG_CGROUP_SCHED kconfig option.

The appropriate option is really CONFIG_CGROUP_CPU. The
QEMU checks already get that right, so no changes needed.

Historically we've used 'unsigned long' and allowed wrapping of negative
numbers for bandwidth values. Add a helper that will simplify adding
support for scaled integers and support for byte granularity while
keeping the compatibility with the older approach.

Fix control flow and spacing issues.

It was too similar to the non-scaled alternative.

VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY and VIR_DOMAIN_PAUSED_POSTCOPY are
used on the source host once migration enters post-copy mode (which
means the domain gets paused on the source. After the destination host
takes over the execution of the domain, its virtual CPUs are resumed and
the domain enters VIR_DOMAIN_RUNNING_POSTCOPY state and
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event is emitted.

In case migration fails during post-copy mode and none of the hosts have
complete state of the domain, both domains will remain paused with
VIR_DOMAIN_PAUSED_POSTCOPY_FAILED reason and an upper layer may decide
what to do.

Even if nss is disabled, the build system tries to build some
targets like libnss_libvirt_impl.la and nsstest. Hide those
under the "if WITH_NSS" block like the rest of NSS plugin bits.

This function is a different beast compared to previous ones.
But yet again, nothing surprising is happening here.
