With iproute2-5.8.0, the route, link and addr show commands fail:
root@sid:~# ip addr show
RTNETLINK answers: Unknown error 352321537
Dump terminated
root@sid:~# ip link show
RTNETLINK answers: Unknown error 352321537
Dump terminated
root@sid:~# ip route show
RTNETLINK answers: Unknown error 352321537
Dump terminated
This patch correctly decodes the GETROUTE and GETLINK commands and adds
the RTA_TABLE message.

Only implement IFLA_PERM_ADDRESS to fix the following error:
Unknown host QEMU_IFLA type: 54
The couple of other ones, IFLA_PROP_LIST and IFLA_ALT_IFNAME, have
been introduced to be used with RTM_NEWLINKPROP, RTM_DELLINKPROP and
RTM_GETLINKPROP that are not implemented by QEMU.

Since most calls to `gemu_log` are actually logging unimplemented features,
this change replaces most non-strace calls to `gemu_log` with calls to
`qemu_log_mask(LOG_UNIMP, ...)`. This allows the user to easily log to
a file, and to mask out these log messages if they desire.
Note: This change is slightly backwards incompatible, since now these
"unimplemented" log messages will not be logged by default.

In any of these `*_for_each_*` functions, the last entry in the buffer (so the
"remaining length in the buffer" `len` is equal to the length of the
entry `nlmsg_len`/`nla_len`/etc) has size that is not a multiple of the
alignment, the aligned lengths `*_ALIGN(*_len)` will be greater than `len`.
Since `len` is unsigned (`size_t`), it underflows and the loop will read
pass the buffer.
This may manifest as random EINVAL or EOPNOTSUPP error on IO or network
system calls.

QEMU_IFLA_BR_MULTI_BOOLOPT has been added to the wrong function
host_to_target_slave_data_bridge_nlattr(). Move it to
host_to_target_data_bridge_nlattr().
This fixes following error:
Unknown QEMU_IFLA_BR type 46
