This partially reverts commit 9b45c9f0.

It changed the default format of socket address from the one SASL
requires, but did not adjust all the callers.

It also removed the test coverage for it.

Revert most of the changes except the virSocketAddrFormatFull support
for URI-formatted strings.

This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1345743 while
reverting the format used by virt-admin's client-info command from
the URI one to the SASL one.

This fixes the disappearance of domains and networks starting with a
dot.

https://bugzilla.redhat.com/show_bug.cgi?id=1333248

The device names are unlikely to start with a dot.
'.' and '..' are already skipped by virDirRead.

The directories we iterate over are unlikely to contain any entries
starting with a dot, other than '.' and '..' which is already skipped
by virDirRead.

'.' and '..' are now skipped by virDirRead, there's no need to mention
them in the comment.

It skips those directory entries.

All of the callers either skip these explicitly, skip all entries
starting with a dot or match the entry name against stricter patterns.

Introduce a helper that only calls closedir if DIR* is non-NULL
and sets it to NULL afterwards.

The only possible error is EBADFD.
Since we only use the directory stream returned by opendir,
this should never happen.

The virUSBDeviceFind* callers do not check errno after calling
this function.

Add 'encinfo' to the extended disk structure. This will contain the
encryption secret (if present).

Add utility to format the virSecretLookupTypeDefPtr in XML

Move to virsecret.c and rename to virSecretLookupParseSecret. Also convert
to usage xmlNodePtr and virXMLPropString rather than virXPathString.

Move the enum into a new src/util/virsecret.h, rename it to be
virSecretLookupType. Add a src/util/virsecret.h in order to perform
a couple of simple operations on the secret XML and virSecretLookupTypeDef
for clearing and copying.

This includes quite a bit of collateral damage, but the goal is to remove
the "virStorage*" and replace with the virSecretLookupType so that it's
easier to to add new lookups that aren't necessarily storage pool related.

Every driver provides a refreshPool impl, and many other critical
places in the code unconditionally call it without checking if
it exists, so this check is pointless

qemu doesn't have any accel2d support wired up. Explicitly error
if a user tries it out, or typos the accel3d option

We should be raising an error if accel3d is present for any
non-virtio video as well, incase someone tries it for say 'qxl'

  One can not issue monitor commands manually during async calls thru
designated API while this could be useful for testing/debugging purposes.
qemuDomainQemuMonitorCommand uses job of type QEMU_JOB_MODIFY and any async
call disable parallel execution of this type of job. The only state that is
changed is taint variable. AFAIU the only place we can mess is resetting
taint flag in qemuProcessStop routine under some async job. But this can not
happen thanx to both virDomainObjIsActive check in qemuDomainQemuMonitorCommand
and resetting active status in qemuProcessStop before taint flag.

  Change job type to QEMU_JOB_QUERY and thus make the API call available for
most of async jobs.

Guest agent interaction is considered privileged.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1349272

Pass 'true' if we are not dealing with a migration.

This code was attempting to handle some implicit <console> XML
formatting for manually assembled DomainDef, since previously the
console<->serial compat copying was only done at XML parse time.

Nowadays it's done via virDomainDefPostParse ->
virDomainDefAddConsoleCompat, which all manual DomainDef builders
already call, so we can drop this workaround.

When domXML contains only <console type='pty'> and no corresponding
<serial>, the console is "stolen" [1] and used as the first <serial>
device. When this "stolen" console is accessed from the libxl driver
(in libxlConsoleCallback and libxlDomainOpenConsole), check if the
targetType is VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL, and use the
"stolen" device in def->serials[0] instead. Prior to this change,
creating a domain with input XML containing only a <console> device
and subsequently attempting to access its console with
'virsh console' would fail

error: internal error: character device <null> is not using a PTY

[1] See comments associated with virDomainDefAddConsoleCompat() in
    $LIBVIRT-SRC/src/conf/domain_conf.c:

We are done if the string ends and move to another nesting
level if we find a dot.

Make rewriting it easier.

Allow modification of specific vCPU states via the guest agent.

Allow gathering available vcpu ids, their state and offlinability via
the qemu guest agent. The maximum id was chosen arbitrarily and ought
to be enough for everybody.

Documentation for the "guest-set-vcpus" command describes a proper
algorithm how to set vcpus. This patch makes the following changes:

- state of cpus that has not changed is not updated
- if the command was partially successful the command is re-tried with
  the rest of the arguments to get a proper error message
- code is more robust against malicious guest agent
- fix testsuite to the new semantics
