We have plenty of completers which iterate over all values of
given enum and do nothing more than translate every member into
string (using corresponding virXXXTypeToString()).
Introduce a convenience function so that callers can pass just
VIR_XXX_LAST and virXXXTypeToString and the rest is taken care
of.

For now this serves just as an annotation because readline and also the
bash completion script insist on completing local paths when an empty
list is returned.
This will serve for future reference once we'll be able to properly
refuse to suggest anything.
The completer is used for fields such as names for new objects,
description strings, password strings etc, URIs and hostnames which we
can't feasibly autocomplete.

For now the completion does the correct thing of completing a local path
if NULL is returned.
Introduce 'virshCompletePathLocalExisting' and use it in the
'VIRSH_COMMON_OPT_FILE' macro.

Introduce a bunch of new virsh commands for managing checkpoints in
isolation. More commands are needed for performing incremental
backups, but these commands were easy to implement by modeling heavily
after virsh-snapshot.c. There is no need for checkpoint-revert or
checkpoint-current since those snapshot APIs have no checkpoint
counterpart. Similarly, it is not necessary to change which
checkpoint is current when redefining from XML, since until we
integrate checkpoints with snapshots, there is only a linear chain
(and you can deduce the current checkpoint by instead using
'checkpoint-list --leaves'). Other aspects of checkpoint-list are
also a bit simpler than the snapshot counterpart, in part because we
don't have to cater to back-compat to older API.
Upcoming patches will test these interfaces once the test driver
supports checkpoints.

virStringListFree via the VIR_AUTOSTRINGLIST macro.

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.

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 IOW, the Author: comments are quickly out of date,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.
