There was an unhandled 'open' call which resulted in:

"error: Library function returned error but did not set virError"

Even if this happens during the daemon's start when we still don't have
any set of outputs defined yet, we can safely report an error, since we
automatically fallback to stderr which is fine even for both
running as a daemonized process, since this happens before the daemon
forks into the background, and running as a systemd service, since
systemd re-directs std outputs to journald by default.

After the release it's necessary to add a new <release> section for the
upcoming release. Add a template so that it does not have to be
compiled over and over again.

In 9e246583 a check that denies internal snapshots when pflash
based loader is configured for the domain. However, if there's
none and an user tries to do an internal snapshot they will
witness daemon crash as in that case vm->def->os.loader is NULL
and we dereference it unconditionally.

CPU features which change their value from disabled to enabled between
two calls to query-cpu-model-expansion (the first with no extra
properties set and the second with 'migratable' property set to false)
can be marked as enabled and non-migratable in qemuMonitorCPUModelInfo.

Since the code consuming qemuMonitorCPUModelInfo currently ignores the
migratable flag, this change is effectively changing the CPU model
advertised in domain capabilities to contain all features (even those
which block migration). And this matches what we do for QEMU older than
2.9.0, when we detect all CPUID bits ourselves without asking QEMU.

As a result of this change

    <cpu mode='host-model'>
      <feature name='invtsc' policy='require'/>
    </cpu>

will work with all QEMU versions. Such CPU definition would be forbidden
with QEMU >= 2.9.0 without this patch.

If calling query-cpu-model-expansion on the 'host'/'max' CPU model with
'migratable' property set to false succeeds, we know QEMU is able to
tell us which features would disable migration. Thus we can mark all
enabled features as migratable.

QEMU is able to tell us whether a CPU feature would block migration or
not. This patch adds support for storing such features in
qemuMonitorCPUModelInfo.

When idx is 0 virStorageFileChainLookup returns the base (bottom) of the
backing chain rather than the top. This is expected by the callers of
qemuDomainGetStorageSourceByDevstr.

Add a special case for idx == 0

Since commit fcbbb289 we steal the pointer to the storage pool
source name if there was no pool name specified.

Properly duplicate the string to avoid freeing it twice.

https://bugzilla.redhat.com/show_bug.cgi?id=1436400

Pool types that have the VIR_STORAGE_POOL_SOURCE_NAME flag set
allow omitting the <name> element and instead fill out the pool name
from the <source><name> element.

Relax the schema to make <name> optional for these pools.
Expressing that at least one of these is required is out of scope
of the schema.

One of the problems with our virGetDomain function is that it
copies just domain name and domain UUID. Therefore it's very
easy to forget aboud domain ID. This can cause some bugs, like
virConnectGetAllDomainStats not reporting proper domain IDs.

Imagine the following scenario:

1) virsh net-start default
2) virsh start myFavouriteDomain
3) virsh net-destroy default
4) virsh destroy myFavouriteDomain

(assuming myFavouriteDomain has an interface from default
network)

Regardless of how unlikely this scenario looks like, we should
not crash. The problem is, on net-destroy in
networkShutdownNetworkVirtual() the virMacMap module is unrefed,
but the stale pointer is kept around. Thus when the domain
destroy procedure comes in, networkReleaseActualDevice() and
subsequently networkMacMgrDel() is called. This function sees the
stale pointer and starts calling the virMacMap module APIs which
work over freed memory.

These tests cover a number of scenarios where we care about
the memory locking limit being set correctly for the guest
to work properly.

This will be used later on in the test suite.

The value we use internally to represent the lack of a memory
locking limit, VIR_DOMAIN_MEMORY_PARAM_UNLIMITED, doesn't
match the value setrlimit() and prlimit() use for the same
purpose, RLIM_INFINITY, so we have to handle the translation
ourselves.

Partially-resolves: https://bugzilla.redhat.com/1431793

For guests that use <memoryBacking><locked>, our only option
is to remove the memory locking limit altogether.

Partially-resolves: https://bugzilla.redhat.com/1431793

Instead of having a separate function, we can simply return
zero from the existing qemuDomainGetMemLockLimitBytes() to
signal the caller that the memory locking limit doesn't need
to be set for the guest.

Having a single function instead of two makes it less likely
that we will use the wrong value, which is exactly what
happened when we started applying the limit that was meant
for VFIO-using guests to <memoryBacking><locked>-using
guests.

This reverts commit c2e60ad0.

Turns out this check is excessively strict: there are ways
other than <memtune><hard_limit> to raise the memory locking
limit for QEMU processes, one prominent example being
tweaking /etc/security/limits.conf.

When reading release notes, patch summary is not always the best
description of what users can expect in new version.  I propose
changing it slightly so that it describes what exactly happens and
when.

However, we do not have to add every single code change to the news
file, that would be ridiculous and unreadable for users.  If the patch
subject needs changes like this one, I'm rather tempted to say that
such changes should not be in the news file at all.  So that would be
the other way how to fix this.

The mock, as well as the test, is only available on Linux.  So skip
building it everywhere else, especially when it fails on mingw.

If if_indextoname is not defined, the whole function using it should
not be defined either.  Add stub to fix build on mingw.

Clean up the virsh man page description for --pool-create-as in order
to better describe how the various arguments are used when creating
(or defining) a logical pool.

Also modify the storage pool XML parsing algorithm to check for the
mismatched "name" and "source-name".

Move the --print-xml to the end of the qualifiers since it's not
properly positionally situated for both --pool-create-as and --pool-define-as
and could be miscontrued as being the 3rd positional argument.
