this fixes the issue that we did not generate the correct repository
url for pbs storages that contained an ipv6 address or a port

Now that VMs can be started during a backup, it makes sense to create a
dirty bitmap in these cases too, since the VM might be resumed and thus
continue running normally even after the backup is done.

Connect and send the vmid of the VM being backed up. This prevents
qmeventd from SIGTERMing the underlying QEMU instance, even if the guest
shuts itself down, until we close the socket connection (in cleanup,
which happens on success and abort, or if we crash the file handle will
be closed as well).

if the 'backup' qmp call itself times out or fails, we still want to
try to cancel the backup, else it can happen that there is still
a backup running even when vzdump thinks it was canceled
qapi docs says that backup cancel always returns success, even
if no backup is running
since we hold a global and a per vm lock for the backup, this should be
ok, since we should not reach this code without that lock

We use verification for something more in-depth on the PBS server, so
avoid that term to avoid misunderstandings.

until we maybe have a 'pbs-backup' that links Qemu and PBS like
'pbs-restore', we need to do a regular backup for the template case to
support all storage types and image formats.

This still works even if all drives were clean. It then shows the very
magical line:
INFO: backup was done incrementally, reused 34.00 GiB (100%)

QEMU handles it just as well as with VMA, so this was probably just
forgotten to implement for PBS.

There can't be a dirty bitmap when the VM was off, and if it was off we
will also shut it down after the backup, so no point in creating one.

When $target is 0, that means we don't have to upload any data, in which
case we're immediately done.
Otherwise incremental backups with no changes display a really weird
status: 0% (0.0 B of 0.0 B), duration 0, read: 0 B/s, write: 0 B/s
when they're actually done already.
Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
Previously 'read' and 'write' would always show the same value, which is
of little use. Change it so 'write' excludes reused bytes, thus
displaying the actual upload speed.
$last_reused needs to be initialized to contain reused data from 'clean'
dirty bitmaps to ensure the first output line is correct.
Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
Uses the new 'query-pbs-bitmap-info' QMP call to retrieve additional
information about each drive's dirty bitmap. Returned info is also used
to calculate $target by simply adding all the dirty values (dirty is
equal to size in case the entire drive will be backed up).
"Backup is sparse" message is suppressed for PBS, since it makes little
sense (if zero chunks appear in the clean area of a bitmap, they won't
be counted, and a user is probably more interested in the 'reused' data
anyway).
Also removes the need for the hacky $first_round query-backup handling.

If 'query-proxmox-support' is not known to QEMU, assume that no other
features are supported either.
If 'pbs' is not supported at all, error out with a nice message.

reuse can also come from the current backup - so drop the "from last
backup" as this can be very confusing if one reads it after making
the first backup ever, with no last backup existing.

normally this is done centrally in the managers code, but we do not
have the info for PBS there.

The $total != $transferred check is changed to a log, as QEMU reports
only actually transferred bytes, and it is indeed correct for
incremental backups to have differing values from $total.
The 'incremental' parameter is always set, QEMU will figure out if it should
re-use an existing bitmap or create a new one on its own.

Move the logic which volumes are included in the backup job to its own
method and adapt the VZDump code accordingly. This makes it possible to
develop other features around backup jobs.

VM was can be true for stop mode backup, we cannot check the "is VM
currently running" as that doesn't tells us anything (could be the
backup process), so check the mode also..

It was necessary to move foreach_volid back to QemuServer.pm
In VZDump/QemuServer.pm and QemuMigrate.pm the dependency on
QemuConfig.pm was already there, just the explicit "use" was missing.
