Most of our completers used the pattern:
if ((nITEM = virITEMListAll()) < 0)
return NULL;
but the virDomainSnapshot and virStorageVolume completers were instead
using goto error. If the ListAll fails with -1, the cleanup label was
running a loop of 'size_t i < int nITEM', which is an extreme waste of
CPU cycles. Broken since their introduction in v4.1.

The function must return a pointer, not a boolean. Fortunately 'false'
is equivalent to 'NULL' so this bug no had ill effect previously.

Strictly speaking, this should go near vshCompleter typedef
declaration. However, I find it more useful near actual completer
implementations.

In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.
In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.
With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to find the
author of a particular bit of code.
This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.
The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

After you go through command mentioned above, completer
finds what state the device is currently in, and suggests
an opposite state.

Functions virshSecretEventNameCompleter, virshPoolEventNameCompleter,
virshNodedevEventNameCompleter allocates only enough space
for array of N strings.
However these are null terminated strings, so program needs to
alloc space for array of N + 1 strings.
How to replicate error: valgrind virsh, use completer for
'nodedev-event --event' or 'pool-event --event' or
'secret-event --event'.

These two functions were duplicating some cleanup paths, so let's just merge
both cleanup and error paths together. To distinguish whether we need to
clean-up the return value let's keep it in @tmp until the function is successful
in which case we set @ret to the value of @tmp and set @tmp to NULL.

Only a small subset of VIR_CONNECT_LIST_DOMAINS_* flags are
actually used for this completer. Remove the unused ones. Note
that this is unrelated to other commands using
VIR_CONNECT_LIST_DOMAINS_* (i.e. cmdList) as this commit targets
the completer only and nothing else.

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.

Now that we have everything prepared let the fun begin. This
completer is very simple and returns domain names. Moreover,
depending on the command it can return just a subset of domains
(e.g. only running/paused/transient/.. ones).
