qemu: hotplug: Remove legacy quirk for 'dimm' address generation
Commit b7798a07f93 (in fall of 2016) changed the way we generate aliases
for 'dimm' memory devices as the alias itself is part of the migration
stream section naming and thus must be treated as ABI.
The code added compatibility layer for VMs with memory hotplug started
with the old scheme to prevent from generating wrong aliases. The
compatibility layer broke though later when 'nvdimm' and 'pmem' devices
were introduced as it wrongly detected them as old configuration.
Now rather than attempting to fix the legacy compat layer to treat other
devices properly we'll be better off simply removing it as it's
extremely unlikely that somebody has a VM started in 2016 running with
today's libvirt and attempts to hotplug more memory.
This fixes a corner case when a user hot-adds a 'dimm' into a VM with a
'dimm' and a 'nvdimm' after restart of libvirtd and then attempts to
migrate the VM.

When a VirtualBox API fails it produced an exception. Until now,
we did not have correct APIs wired up to get the exception and

virReportError("virtualbox API failed, rc=%08x", rc);
This is not very user friendly because those rc values are hard

and some other value) and also it expects users to know where to
look.
But now that we have all machinery needed for querying
exceptions, vboxReportError() can be introduced. The aim is to
query VirtualBox exceptions and append them after the error
message we intent to report. If the exception can't be queried
successfully, this behaves exactly like virReportError().

network: Increase max route size when checking IPv6 forwarding
In d9ee51e, virNetDevIPCheckIPv6Forwarding was updated to walk the
contents of /proc/net/ipv6_route so that it could check to see if the
RTF_ADDRCONF was set on any IPv6 routes to ultimately determine if
enabling forwarding would result in an error due to accept_ra=1 being
set on the interface.
The implementation added in that commit limited the number of routes
that could be read from /proc/net/ipv6_route to 100_000, each with 150
characters. This is problematic for machines that have a full IPv6
routing table, as the IPv6 routing table has now grown to over 160_000
(it was closer to 100_000 at the time of that commit).
This patch increases the maximum route size from 100_000 to 1_000_000.
While a million routes is somewhat arbitrary, it's meant to be a value
that can be supported for the forseeable future. APNIC, one of the five
regional internet registries, recently published a forecast of IPv6
table growth which anticipates a worst-case growth to 1_000_000 in
January of 2029.

Every enum/struct/union implicitly includes a typedef in the
emitted C code. Furthermore, the syntax used to declare the
redundant typedef is not compliant with the XDR spec.

docs: document correct cpu shares limits with both cgroups v1 and v2
The limits are different with cgroups v1 and v2 but our XML
documentation and virsh manpage mentioned only cgroups v1 limits without
explicitly saying it only applies to cgroups v1.

domain_validate: drop cpu.shares cgroup check
This check is done when VM is defined but doesn't take into account what
cgroups version is currently used on the host system so it doesn't work
correctly.
To make proper check at this point we would have to figure out cgroups
version while defining a VM but that will still not guarantee that the
VM will start correctly in the future as the host may be rebooted with
different cgroups version.
