Michal Privoznik 74416b1d48 m4: Check for rl_completion_quote_character
Apparently we can't assume that people run readline recent enough
to have rl_completion_quote_character (added in readline-5.0
released in 2011). However, we can't compile without it. So if
not present, disable readline.

The functions defined in these sources are referenced all over

Thus when building without it linker gets sad as it can't find

Michal Privoznik 98bc781b42 vshReadlineOptionsGenerator: Don't add already specified options to the list
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.

Michal Privoznik 7e7db4bfe0 virsh: Introduce virshDomainInterfaceCompleter
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.

Michal Privoznik 2e688d96a4 vshCommandStringParse: Allow retrieving partial result
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.

Michal Privoznik db98e7f67e qemuDomainAttachDeviceMknodHelper: Remove symlink before creating it
https://bugzilla.redhat.com/show_bug.cgi?id=1528502

So imagine you have /dev/blah symlink which points to /dev/sda.
You attach /dev/blah as disk to your domain. Libvirt correctly
creates the /dev/blah -> /dev/sda symlink in the qemu namespace.
However, then you detach the disk, change the symlink so that it
points to /dev/sdb and tries to attach the disk again. This time,
however, the attach fails (well, qemu attaches wrong disk)
because the code assumes that symlinks don't change. Well they
do.

This is inspired by test fix written by Eduardo Habkost.

If driver that is calling the parse supports user supplied

avoid any clashes with aliases that libvirt generates, the user
ones have to have "ua-" prefix.

Note, that some drivers don't have notion of device aliases at
all. Also, in order to support user supplied aliases some extra
checks need to be done (e.g. during hotplug). Therefore we can't
just enable this feature for all the drivers. Thus we need a flag

Now, to identify such cases like this one STRPREFIX() is used.
That is not good enough. While it works for [/dev/foo/bar;
/dev/foo] case, it fails for [/dev/prefix; /dev/prefix2] where
the strings share the same prefix but are in fact two different
