What code tries to achieve is that if no flags were provided to
either 'setmem' or 'setmaxmem' commands then the old (no flags)
API is called to be able to communicate with older daemons.
Well, the code can be simplified a bit.
Note that with this change the old no flag version of APIs is
used more often. Previously if --current argument was given it
resulted in *Flags() version to be called even though it is not
necessary - VIR_DOMAIN_AFFECT_CURRENT is implied.
Therefore, this change in fact allows virsh to talk with broader
set of daemons. No other user visible changes were made.

When removing SSH keys via set-user-sshkeys virsh command, then
files to remove are read from passed file. But when
experimenting, I've passed /dev/null as the file which resulted
in API checks which caught that @keys argument of
virDomainAuthorizedSSHKeysSet() can't be NULL. This is because if
the file is empty then its content is an empty string and thus
the buffer the file was read in to is not NULL.
Long story short, error is reported correctly, but it's not
necessary to go through public API to catch it.

In v6.10.0-rc1~104 I've added a virsh command that exposes
virDomainAuthorizedSSHKeysSet() API under "set-user-sshkeys"
command. The command accepts mutually exclusive "--reset" and
"--remove" options (among others). While the former controls the
VIR_DOMAIN_AUTHORIZED_SSH_KEYS_SET_APPEND flag, the latter
controls the VIR_DOMAIN_AUTHORIZED_SSH_KEYS_SET_REMOVE flag.
These flags are also mutually exclusive. But the code that sets
them has a logical error which may result in both flags being
set. In fact, this results in user being not able to set just the
remove flag.

This patch adds new schema and adds support for parsing and formatting
domain configurations that include vdpa devices.
vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.
When a device on the host is bound to an appropriate vendor-specific
driver, it will create a chardev on the host at e.g. /dev/vhost-vdpa-0.
That chardev path can then be used to define a new interface with
type='vdpa'.
