Add support for the new IFLA_GRO_MAX_SIZE attribute which is needed to
enable BIG TCP[1] properly. Define the attribute in the local link
attributes (nl/link_linux.go) because it isn't yet present in Go's
x/sys/unix package. Also add a test for it.

Adding an xfrmi link with if_id 0 results in EINVAL being returned, see
[1]. Adjust TestLinkAddDelXfrmiNoId accordingly to expect an error.

When the LinkModify was merged in [1] a function
that exports it outside of pkgHandle was never
added like is available for LinkAdd, LinkDel etc.
Update testing to use exported LinkModify that
itself calls the pkgHandle.LinkModify function.

Provide the status of the allmulticast option via the highlevel
link attributes instead of requiring raw flag handling.
Avoid comparing all rawflags before and after in tests due to that
the IFF_RUNNING flag might change independenly.

Creating a veth pair across namespaces now is a multistep process.
Doing it in one shot with this change is clearer as current
namespace never sees peer IF. Also, moving peer into a namespace
may be rather slow, so better avoided.
This PR refers to PR@lebauce and add some changes.
- Added some tests to retrieve bond slave information.
- Link.BondSlave is changed to LinkSlave interface.
- BondSlaveState.String() returns UPPER case. (same as iproute2)
- BondSlaveMiiStatus.String() returns UPPER case. (same as iproute2)
This deserializes the tx queue, and rx queue count on link
deserialization. We already supported it on serialization.

For tuntap interfaces, return a TunTap Interface instead of
a Generic link when retrieving the interface.
Use netlink extended attributes to populate the Link attributes
for the tuntap link.
In case of older tun driver which does not provide these
attributes, use sysfs to retrieve these attributes.
This commit also adds Owner and Group attributes for the TunTap
Link.

XFRM interfaces are available in Linux Kernel 4.19+
When an IF_ID is applied to a XFRM policy and state, the corresponding
traffic will be sent through the virtual interface with the same IF_ID.
Allow the caller to specify the desired link index at link creation.
This is equivalent to
ip link add link eth0 name testmacvtap index 1000 type macvtap
ip link add dummy1 index 1001 type dummy

For link, address, route, add a `WithOptions` variant to the
`*Subscribe()` function to specify a namespace and an error
callback. Those options can be extended in the future without adding
more functions. For example, it could be possible to subscribe only
for a given family by adding a `Family` member to the appropriate
struct.
As a minor change, the private function is always suffixed by `At`,
since it was the case for route and raw netlink functions (but not for
address and link).
Add support for creating and managing gre tunnels.
This is equivalent to
Point to Point:
ip tunnel add tun4 mode gre local 192.0.2.1 remote 203.0.113.6 key 123
Point to Multipoint:
ip tunnel add tun8 mode gre local 192.0.2.1 key 1234
