CA-223676: Add function `get_physical_interfaces` to networkd

If `ip link set` is used OVS will keep changing it back to the default MTU.

OVS.set_mtu is a new function (since ed2151f), which requires a newer version
of the OVS that supports the mtu_request feature. If the installed OVS does not
have this feature, then the function will raise an exception. For compatibility
reasons, we now catch this exception and fall back to Ip.link_set_mtu.

Sisyphus can tell us these details nowadays, so we can read them
from the relevant files rather than going through the C bindings.

The existing C bindings cannot cope with speeds such as
50 Gbits/second and higher.

Therefore this commit removes the get_status functions from the
C stub and removes the Bindings module that uses it, and adds a
replacement get_status function in the Sysfs module; it returns
the same (speed, duplex) pair as the old function.

It is no longer needed, so remove the file and the _oasis line that
refers to it.

Then re-run "oasis setup" to regenerate
_tags, setup.ml and myocamlbuild.ml

Backport CP-22034 to lcm branch

DNS%d= is written by host-installer,
and DNS= would've been written by the non-hotfixed version of XAPI on
pool eject/network reset.
DNS1 could contain comma-separated values too, handle this by splitting each
value and then List.concat at the end.

CA-324959: suppport both DNS= and DNS%d= formats

This results in an empty /etc/resolv.conf when using static IPs:
```
systemctl stop xcp-networkd
rm /var/lib/xcp/networkd.db
systemctl start xcp-networkd
```

CP-32106: backport of CA-323765

Signed-off-by: Rob Hoes <[email protected]>

When asked to create a bridge, when need to destroy an existing bridge with the
same name _only_ when a the existing bridge is a "real" (non-VLAN) bridge, and
the new one is a "fake" VLAN bridge. Otherwise, the function
`OVS.create_bridge`, which must be idempotent, should leave the bridge alone to
as to not disturb the system.

Backport of ef3aed4.
