qemu: Fix updating device with boot order
Commit v3.7.0-14-gc57f3fd2f8 prevented adding a <boot order='x'/>

However, as a result of that change updating any device with boot order

"another device" is in fact the device which is being updated.
To fix this we have to ignore the device which we're about to update

m4: enforce that all enum cases are listed in switch statements
As a general rule any time we switch() on something that is an enum, we
want to have a case for every enum constant. The -Wswitch warning will
report any switch where we've violated this rule, except if that switch
has a default case.
Unfortunately it is reasonable to want to list all enum constants *and*
also have a default case. To get a warning in that scenario requires
that we turn on -Wswitch-enum.
In a few cases where we explicitly don't want to list all enum cases, we
can discard the enum type checking by casting the value to a plain int.

Fix build with GCC 8 new switch fallthrough warnings
GCC 8 became more fussy about detecting switch
fallthroughs. First it doesn't like it if you have
a fallthrough attribute that is not before a case
statement. e.g.
FOO:
BAR:
WIZZ:
ATTRIBUTE_FALLTHROUGH;
Is unacceptable as there's no final case statement,
so while FOO & BAR are falling through, WIZZ is
not falling through. IOW, GCC wants us to write
FOO:
BAR:
ATTRIBUTE_FALLTHROUGH;
WIZZ:
Second, it will report risk of fallthrough even if you
have a case statement for every single enum value, but
only if the switch is nested inside another switch and
the outer case statement has no final break. This is
is arguably valid because despite the fact that we have
cast from "int" to the enum typedef, nothing guarantees
that the variable we're switching on only contains values
that have corresponding switch labels. e.g.
int domstate = 87539319;
switch ((virDomainState)domstate) {
...
}
will not match enum value, but also not raise any kind
of compiler warning. So it is right to complain about
risk of fallthrough if no default: is present.

conf: add enum constants for default controller models
The controller model is slightly unusual in that the default value is
-1, not 0. As a result the default value is not covered by any of the
existing enum cases. This in turn means that any switch() statements
that think they have covered all cases, will in fact not match the
default value at all. In the qemuDomainDeviceCalculatePCIConnectFlags()
method this has caused a serious mistake where we fallthrough from the
SCSI controller case, to the VirtioSerial controller case, and from
the USB controller case to the IDE controller case.
By adding explicit enum constant starting at -1, we can ensure switches
remember to handle the default case.

conf: move 'generated' member from virMacAddr to virDomainNetDef
Commit 7e62c4cd26d (first appearing in libvirt-3.9.0 as a resolution
to rhbz #1343919) added a "generated" attribute to virMacAddr that was
set whenever a mac address was auto-generated by libvirt. This
knowledge was used in a single place - when trying to match a NetDef
from the Domain to Delete with user-provided XML. Since the XML parser
always auto-generates a MAC address for NetDefs when none is provided,
it was previously impossible to make a search where the MAC address
isn't significant, but the addition of the "generated" attribute made
it possible for the search function to ignore auto-generated MACs.
This implementation had a problem though - it was adding a field to a
"low level" struct - virMacAddr - which is used in other places with
the assumption that it contains exactly a 6 byte MAC address and
nothing else. In particular, virNWFilterSnoopEthHdr uses virMacAddr as
part of the definition of an ethernet packet header, whose layout must
of course match an actual ethernet packet. Adding the extra bools into
virNWFilterSnoopEthHdr caused the nwfilter driver's "IP discovery via
DHCP packet snooping" functionality to mysteriously stop working.
In order to fix that behavior, and prevent potential future similar
odd behavior, this patch moves the "generated" member out of
virMacAddr (so that it is again really is just a MAC address) into
virDomainNetDef, and sets it only when virDomainNetGenerateMAC() is
called from virDomainNetDefParseXML() (which is the only time we care
about it).
