Currently if cmd->skipChecks is set (done only from completers)
some basic checks are skipped because we're working over
partially parsed command. See a26ff63ae4 for more detailed
explanation. Anyway, the referenced commit was too aggressive in
disabling checks and effectively returned success even in clear
case of failure. For instance:
# domif-getlink --interface <TAB><TAB>
causes virshDomainInterfaceCompleter() to be called, which calls
virshDomainGetXML() which eventually calls
vshCommandOptStringReq(.., name = "domain"); The --domain
argument is required for the command and if not present -1 should
be returned to tell the caller the argument was not found. Well,
zero is returned meaning the argument was not found but it's not
required either.

The commands which requires a pool to perform any action for a volume is
throwing a segfault when you pass the volume name before a pool name or
without the argument '--pool'.
An example that works:
virsh # vol-list loops-pool
Name Path
-------------------------------------------------------------------
loop0 /mnt/loop0
virsh # vol-info --pool loops-pool lo<TAB>
An example that does not work:
virsh # vol-list loops-pool
Name Path
-------------------------------------------------------------------
loop0 /mnt/loop0
virsh # vol-info lo<TAB>
Segmentation Fault
The example 'vol-info' can be executed as 'vol-info loop0 --pool
loops-pool'. So, this commit fixes this problem when the arguments are
inverted and avoids the segfault.

Previously we've removed the data only in virshUpdateDiskXML when
changing the disk source for the CDROM since the backing store would be
invalid. Move the code into a separate function and callit from
virshFindDisk which is also used when detaching disk.
The detaching code does not necessarily need to get the full backing
chain since it will need to act on the one managed by libvirt anyways
and this also takes care of problems when parts of the backing store
were invalid due to buggy RBD detection code.

Undefined symbols are a bad thing in general because they can get
resolved in unexpected ways at runtime if multiple sources provide the
same symbol name. For example both glibc and libtirpc may provide XDR
symbols and we want to ensure that we resolve to libtirpc if that's what
we originally built against.
The toolchain maintainers thus strongly recommend that all applications
use the '-z defs' linker flag to prevent undefined symbols. This is
shortly becoming part of the default linker flags for RPMs. As an added
benefit this aligns Linux builds with Windows builds, where the linker
has never permitted undefined symbols.

Currently when the script validates the PKI files and
the certificate 'Subject:' field contains RDNs after
the Common Name (CN), these values are also included,
creating a false result that the CN is not correct.
A small change to the sed regex fixes this issue, by
extracting only the value for CN and nothing else. The
regex is replaced with the exact same regex used to
extract the CN value from the client certificate.
"ln" will not replace an existing symlink, so if you run 'make install'
twice, the second time will get an error:
ln: failed to create symbolic link 'virsh': File exists

The bash-completion project documents that only those scripts
from $BASH_COMPLETIONS_DIR that share name with the current
command for which <TAB> was hit are loaded [1]. This means, that
vsh script we have there is not loaded. We have to create
symlinks for virsh and virt-admin.
At the same time, we have to create new RPM package because
virt-admin and client packages are independent. That means we
cannot place the vsh script in either of them. What we can do is
to have a different package that contains the completion script
and then virt-admin and client packages contain only the symlink
and require the bash-completion package.

Unfortunately, we have a number of aliases in virsh and even though
these are not visible any more, we have to support them. The problem is

These helpers are called from a single place only - cmdHelp wrapper and
just before the wrapper invokes the helpers, it performs the search,
either for command group or for the command itself, except the result is
discarded and the helper therefore needs to do it again. Drop this
inefficient handling and pass the @def structure rather than a name,
thus preventing the helper from needing to perform the search again.

The current state of art is as follows:
1) vshReadlineOptionsGenerator() generate all possible --options
for given command, and then
2) vshReadlineOptionsPrune() clears out already provided ones
from the list.
Not only this brings needless memory complexity it is also not
trivial to get right. We can switch to easier approach: just
don't add already specified --options in the first step.

For given domain fetch list of defined interfaces. This can be
used for commands like domif-getlink and others. If available,
the interface name is returned (e.g. "vnet0", usually available
only for running domains), if not the MAC address is returned.
Moreover, the detach-interface command requires only MAC address
and therefore we have new flag that forces the completer to
return just the MAC address.

When returning a string that needs escaping there are two
scenarios that can happen. Firstly, user already started the
string with a quote (or double quote) in which case we don't need

In the future, this function is going to be called from
vshReadlineParse() to provide parsed input for completer
callbacks. The idea is to allow the callbacks to provide more
specific data. For instance, for the following input:
virsh # domifaddr --domain fedora --interface <TAB><TAB>
the --interface completer callback is going to be called. Now, it
is more user friendly if the completer offers only those
interfaces found in 'fedora' domain. But in order to do that it
needs to be able to retrieve partially parsed result.
