/**
* A completer callback is a function that accepts three arguments:
*
* @ctl: virsh control structure
* @cmd: parsed input
* @flags: optional flags to alter completer's behaviour
*
* The @ctl contains connection to the daemon (should the
* completer need it). Any completer that requires a connection
* must check whether connection is still alive.
*
* The @cmd contains parsed user input which might be missing
* some arguments (if user is still typing the command), but may
* already contain important data. For instance if the completer
* needs domain XML it may inspect @cmd to find --domain. Using
* existing wrappers is advised. If @cmd does not contain all
* necessary bits, completer might return sensible defaults (i.e.
* generic values not tailored to specific use case) or return
* NULL (i.e. no strings are offered to the user for completion).
*
* The @flags contains a .completer_flags value defined for each
* use or 0 if no .completer_flags were specified. If a completer
* is generic enough @flags can be used to alter its behaviour.
* For instance, a completer to fetch names of domains can use
* @flags to return names of only domains in a particular state
* that the command accepts.
*
* Under no circumstances should a completer output anything.
* Neither to stdout nor to stderr. This would harm the user
* experience.

/**
* virshCommaStringListComplete:
* @input: user input so far
* @options: ALL options available for argument
*
* Some arguments to our commands accept the following form:
*
* virsh command --arg str1,str2,str3
*
* This does not play nicely with our completer funtions, because
* they have to return strings prepended with user's input. For
* instance:
*
* str1,str2,str3,strA
* str1,str2,str3,strB
* str1,str2,str3,strC
*
* This helper function takes care of that. In this specific case
* it would be called as follows:
*
* virshCommaStringListComplete("str1,str2,str3",
* {"strA", "strB", "strC", NULL});
*
* Returns: string list of completions on success,
* NULL otherwise.
