3caa28dc50 src: replace gmtime_r/localtime_r/strftime with GDateTime
gmtime_r/localtime_r are mostly used in combination with
strftime to format timestamps in libvirt. This can all
be replaced with GDateTime resulting in simpler code
that is also more portable.

There is some boundary condition problem in parsing POSIX
timezone offsets in GLib which tickles our test suite.
The test suite is hacked to avoid the problem. The upsteam

13fa7b587f virsh: Fix virshDomainInterfaceSourceCompleter
Introduced in v5.10.0-449-gcf44ec5577 it used
virshCommaStringListComplete() to generate list of options. But
this is not correct because the '--source' argument of the
'domifaddr' doesn't accept a string list (for instance
"arp,agent,lease") rather than a single string. Therefore, the
completer must return these strings separately and thus must
refrain from using virshCommaStringListComplete().

At the same time, now that we have strings we need declared as
an enum we can use TypeToString() instead of copying strings.

5be0d28b3e fixed handling of sourceless disks in 'domblkinfo' cmd
virDomainGetBlockInfo() returns error if called on a disk with no
source (a sourceless disk might be a removable media drive with no
media in it, for instance an empty CDROM or floppy drive).

So far this caused the virsh domblkinfo --all command to abort and
ignore any remaining (not yet displayed) disk devices.  This patch
fixes the problem by first checking for existence of a <source>
element in the corresponding XML.  If none is found, we avoid calling
virDomainGetBlockInfo() altogether as we know it's bound to fail in
that case.

689beaa47c backup: Implement virsh support for checkpoints
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.

Missing semicolon at the end of macros can confuse some analyzers

Move the verify() statement to the end of the macro and drop

semicolon.

While we are touching these call sites, standardize on putting
