If we encounter a video device with primary=yes, we insert it
at def->videos[0].
There is no need to record this in a separate variable,
just check if there already is a primary video at def->videos[0].
We call VIR_INSERT_ELEMENT_INPLACE either with 0 (for primary video)
or def->nvideos (for the rest).
Use a variable with more semantic name, since j is usually used
for iterating.
We start with both i and def->nvideos at 0 and increment both
after every successful iteration.
Use i directly, instead of passing the def->nvideos value through j.
Commit 119cd06 started setting the primary bool for the first
user-specified video even if user omitted the 'primary' attribute.
However this was done before the addition of the implicit device.
This broke startup of transient qemu domains with no <video>:

Move this default to virDomainDefPostParseInternal,
after the addition of the implicit video device, to catch the implicit
video as well.
Being consistent is nice, especially when it comes to defining our
regular expression, where using single quotes instead of double
quotes allows us to leave out a few backslashes.
Changing this required altering a few error messages.
The only remaining use of double quotes is one where they are
actually required for the check to work.
Quite straigthforward as vz sdk memory setting function makes
just what we want to that is set "amount of physical memory
allocated to a domain".
'useflags' is introduced for non flag function implementation.
We can't just use combination of flags like "live | config" or
we fail for inactive domains. Other combinations have drawbacks
too.

Actually this is not pure refactoring. Part of common code is
replaced with virDomainObjUpdateModificationImpact and this
a good replacement. It includes removed check of inactive
domain and active flags set. Additionally we resolve
current flag in accordance with current state of domain.
Thus it becames possible to attach/detach devices for
inactive domains if this flag is set.

Replace the nonsensical debug statement by adding the expected event
code into the existing debug statement.
Since the monitor code always notifies the agent on guest
reboot/shutdown even if that was not initiated by the agent the warning
emitted later is bogus and pollutes the logs in such cases. Delete it
and keep just the original debug message where this info can be
inferred.
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.
The check is supposed to stop users from trying to compile
virt-login-shell on Windows by erroring out during the
configure phase; however, there are two flaws in it:
* the value of "x$with_win" is compared to "yes" instead
of "xyes" (note the "x" in the first string)
* "test" is not being used, so the script will actually
try to run a command called "x$with_win" instead of
performing string comparison
This patch fixes both issues.
Commit e72667bd tried to fix the incorrect file ordering in po/POTFILES.in
except it didn't, since the sort was run using locale en_US instead of
using locale C which is the default in libvirt. So this patch hopefully fixes
it for good.

When it comes to a situation that a new translatable file needs to be added
into the list of files, an automatically generated patch is proposed during
syntax-check. However, the diff was made against a sorted list of files and
the same sorted list of files + the new file that actually needs to be added
into the list. Since we do not keep POTFILES sorted, the proposed patch thus
can't be applied...most of the time - depending on the context.

Explicitly add Linux and BSD syms files for nss to EXTRA_DIST

Some places already check for "virt-" prefix as well as plain "virt".
virQEMUCapsHasPCIMultiBus did not, resulting in multiple PCI devices

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.

FreeBSD lacks ENODATA, and viruuid.c redefines it to EIO, but it's not
actually using it. On the other hand, we have virrandom.c that's using
ENODATA. So make this re-definition common by moving it to internal.h,
so all the current and possible future users don't need to care about
that.
In the latest libxenlight code, libxl_domain_create_restore accepts a

Our use of gnutls_rnd(), introduced with commit ad7520e8, is
conditional to the availability of the <gnutls/crypto.h> header
file.
Such check, however, turns out not to be strict enough, as there
are some versions of GnuTLS (eg. 2.8.5 from CentOS 6) that provide
the header file, but not the function itself, which was introduced
only in GnuTLS 2.12.0.
Introduce an explicit check for the function.
The variables used for storing CFLAGS and LIBS before temporarily
modifying them was consistent when it comes to the name, but not
when it comes to the case.
Make sure names are completely consistent.
The previous value of CFLAGS was saved as old_cflags but later
restored from old_CFLAGS, which is clearly not correct.
Restore CFLAGS from the right variable.
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.
As usual we try to deal correctly with vz domains that were
created by other means and thus can have all range of SDK domain
parameters. If vz domain boot order can't be represented
in libvirt os boot section let's give warning and make os boot section
represent SDK to some extent.
1. Os boot section supports up to 4 boot devices. Here we just
cut SDK boot order up to this limit. Not too bad.
2. If there is a floppy in boot order let's just skip it.
Anyway we don't show it in the xml. Not too bad too.
3. SDK boot order with unsupported disks order. Say we have "hdb, hda" in
SDK. We can not present this thru os boot order. Well let's just
give warning but leave double <boot dev='hd'/> in xml. It's
kind of misleading but we warn you!
SDK boot order have an extra parameters 'inUse' and 'sequenceIndex'
which makes our task more complicated. In realitly however 'inUse'
is always on and 'sequenceIndex' is not less than 'boot position index'
which simplifies out task back again! To be on a safe side let's explicitly
check for this conditions!
We have another exercise here. We want to check for unrepresentable
condition 3 (see above). The tricky part is that in contrast to
domains defined thru this driver 3-rd party defined domains can
have device ordering different from default. Thus we need
some id to check that N-th boot disk of os boot section is same as
N-th boot disk of SDK boot. This is what prlsdkBootOrderCheck
for. It uses disks sources paths as id for disks and iface names
for network devices.
