(also fixes#3011)
Deprecates the old-style 'boot' and 'bootdisk' options by adding a new
'order=' subproperty to 'boot'.
This allows a user to specify more than one disk in the boot order,
helping with newer versions of SeaBIOS/OVMF where disks without a
bootindex won't be initialized at all (breaks soft-raid and some LVM
setups).
This also allows specifying a bootindex for USB and hostpci devices,
which was not possible before. Floppy boot support is not supported in
the new model, but I doubt that will be a problem (AFAICT we can't even
attach floppy disks to a VM?).
Default behaviour is intended to stay the same, i.e. while new VMs will
receive the new 'order' property, it will be set so the VM starts the
same as before (using get_default_bootorder).

The format is unused in this commit, but will replace the current
string-based format of the 'boot' property. It is included since the
parameter of bootorder_from_legacy follows it.
Two helper methods are introduced:
* bootorder_from_legacy: Parses the legacy format into a hash closer to
what the new format represents
* get_default_bootdevices: Encapsulates the legacy default behaviour if
nothing is specified in the boot order
resolve_first_disk is simplified and gets a new $cdrom parameter to
control the behaviour of excluding CD-ROMs or instead searching for only
them.

Pass new size directly, so the function doesn't need to know about
how some hash is organized. And return a message directly, instead
of both size-strings. Also dropped the wantarray, because both
existing callers use the message anyways.

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.

Moved code so that initialization of drivedesc_hash stays a single block.
Avoid auto-vivication in parse_drive.

and make it match with what parse_drive does. Even though the 'real' format
was pve-volume-id, callers already expected that parse_drive returns a hash
with a valid 'file' key (e.g. PVE/API2/Qemu.pm:1147ff).

If for whatever reason there is no size in the property string
of a drive, 'qm rescan' would do nothing for that drive and
live migration would also fail.
Also adds a check to avoid potential auto-vivification of volid_hash->{$volid}

The initialization for the drive keys in $confdesc is changed
to be a single for-loop iterating over the keys of $drivedesc_hash and
the initialization of the unusedN keys is move to directly below it.
To avoid the need to change all the call sites, functions with more than
a few callers are exported from the submodule and imported into QemuServer.pm.
For callers of the now imported functions within QemuServer.pm, the prefix
PVE::QemuServer is dropped, because it is unnecessary and now even confusing.
