Refactor the very old opaque logic (using multiple bitmaps) by
fully-allocating vshCmdOpt for each possible argument and then filling
them as they go rather than allocating them each time after it's parsed.
This simplifies the checkers and removes the need to cross-reference
multiple arrays.

Currently the code decides which option to complete by looking into the
input string and trying to infer it based on whether we are at the
end position as we truncate the string to complete to the current cursor
position.
That basically means that only the last-parsed option will be up for
completion.
Replace the logic by remembering which is the last option rather than
using two different position checks and base the completion decision on
that and the actual value of the last argument (see comment).

While the 'complete' command is meant to be hidden and used only for
the completion script, there's nothing preventing it being used in all
virsh modes.
This poses a problem as the command tries to close 'stdin' to avoid the
possibility that an auth callback would want to read the password.
In interactive mode this immediately terminates virsh and in
non-interactive mode it attempts to close it multiple times if you use
virsh in batch mode.
Fix the issues by using virOnce() to close it exactly once and do so
only in non-interactive mode.

'vshReadlineInit' is called when interactive virsh is started but also
on each call to 'cmdComplete'. Calling it repeatedly (using the

The buffer which we assign to the 'rl_line_buffer' variable of readline

Free/clear it after it's used.
Hitting this leak was until recenly possible only in non-interactive

used multiple times now interactively.

The "quantum" attribute of HTB is documented as:
Number of bytes to serve from this class before the scheduler
moves to the next class.
Since v1.3.2-rc1~225 we compute what we think is the appropriate
value and pass it on the TC command line. But kernel and
subsequently TC use uint32_t to store this value. If we compute
value outside of this type then TC fails and prints usage which
we then interpret as an error message. Needlessly long error
message. While there's not much we can do about the latter, we
can put a cap on the value and stop tickling this behavior of TC.

Commit v10.0.0-265-ge67bca23e4 added a `active_config` and
`defined_config` to nodedev mdev internal XML handling.
`defined_config` can be filled at XML parse time, but `active_config`
must be filled in by nodedev driver. This wasn't implemented for the
test driver however, which caused virt-manager test suite regressions.
Working example:
```
$ virsh --connect test:///home/crobinso/src/virt-manager/tests/data/testdriver/testdriver.xml nodedev-dumpxml mdev_8e37ee90_2b51_45e3_9b25_bf8283c03110

<parent>css_0_0_0023</parent>
<capability type='mdev'>
<type id='vfio_ccw-io'/>
<iommuGroup number='0'/>
</capability>
</device>
```
Broken example:
```
$ virsh --connect test:///home/crobinso/src/virt-manager/tests/data/testdriver/testdriver.xml nodedev-dumpxml mdev_8e37ee90_2b51_45e3_9b25_bf8283c03110

<capability type='mdev'>

There's already code that does what we want in the test suite.
Move it to a shared function, and call it in test driver when
creating a nodedev from driver startup XML.

While QEMU accepts and interprets an empty string in the tls-hostname
field in migration parametes as if it's unset, the same does not apply
for the 'tls-hostname' field when 'blockdev-add'-ing a NBD backend for
non-shared storage migration.
When libvirt sets up migation with TLS in 'qemuMigrationParamsEnableTLS'
the QEMU_MIGRATION_PARAM_TLS_HOSTNAME migration parameter will be set to
empty string in case when the 'hostname' argument is passed as NULL.
Later on when setting up the NBD connections for non-shared storage
migration 'qemuMigrationParamsGetTLSHostname', which fetches the value
of the aforementioned TLS parameter.
This bug was mostly latent until recently as libvirt used
MIGRATION_DEST_CONNECT_HOST mode in most cases which required the
hostname to be passed, thus the parameter was set properly.
This changed with 8d693d79c4 for post-copy migration, where libvirt now
instructs qemu to connect and thus passes NULL hostname to
qemuMigrationParamsEnableTLS, which in turn causes libvirt to try to
add NBD connection with empty string as tls-hostname resulting in:
error: internal error: unable to execute QEMU command 'blockdev-add': Certificate does not match the hostname
To address this modify 'qemuMigrationParamsGetTLSHostname' to undo the
weird semantics the migration code uses to handle TLS hostname and make
it return NULL if the hostname is an empty string.

Since OVS keeps desired state in a DB, upon sudden crash of the
host we may leave a port behind. There's no problem on VM
shutdown or NIC hotunplug as we call corresponding del-port
function (virNetDevOpenvswitchRemovePort()). But if the host
suddenly crashes we won't ever do that. What happens next, is
when OVS starts it finds desired state in its DB and creates a
stale port.
OVS added support for transient ports in v2.5.0 (Feb 2016) and
since its v2.9.0 it even installs a systemd service
(ovs-delete-transient-ports) that automatically deletes transient
ports on system startup. If we mark a port as transient then OVS
won't restore its state on restart after crash.
This change may render "--may-exist" argument redundant, but I'm
not sure about all the implications if it was removed. Let's keep
it for now.

There are PCI devices with pretty large non-prefetchable memory,
for instance:
Memory at 9d800000 (64-bit, non-prefetchable) [size=8M]
Memory at a6800000 (64-bit, non-prefetchable) [size=16K]
For cold plugged devices this is not a problem, because firmware
sets PCI controllers in a way that make devices behind them just
work. Problem arises if such PCI device is to be hot plugged.
Since the PCI device wasn't present at cold boot, firmware could
not take it into calculations and the amount of reserved memory
is not sufficient.
Introduce a know that allows users overriding value computed by
FW and thus allow hot plug of such PCI devices.

The purpose of ERROR() macro in our NSS module is to print error
message provided as arguments followed by error string
corresponding to errno. Historically, we've used strerror_r() for
that (please note, we want our NSS module to be free of libvirt
internal functions, or glib even - hence, g_strerror() is off the
table).
Now strerror_r() is documented as:
Returns ... a pointer to a string that the function stores in
buf, or a pointer to some (immutable) static string (in which
case buf is unused).
Therefore, we can't rely the string being stored in the buf and
really need to store the retval and print that instead.
While touching this area, decrease the ebuf size, since its
current size (1KiB) is triggering our stack limit (2KiB) in some
cases.

Ages ago origCPU in domain private data was introduced to provide
backward compatibility when migrating to an old libvirt, which did not
support fetching updated CPU definition from QEMU. Thus origCPU will
contain the original CPU definition before such update. But only if the
update actually changed anything. Let's always fill origCPU with the
original definition when starting a domain so that we can rely on it
being always set, even if it matches the updated definition.
This fixes migration or save operations with custom domain XML after
commit v10.1.0-88-g14d3517410, which expected origCPU to be always set
to the CPU definition from inactive XML to check features explicitly
requested by a user.
