The next patch introduces a new mlxsw-specific test that uses
mirror_gre_lib.sh and mirror_gre_topo_lib.sh.
However when sourcing their own deps, these libraries assume that the
test that's running is in the same directory. That's not the case for
driver-specific tests.
So change the libraries to source their deps through $relative_path.
That variable is set up by lib.sh, which should be imported by the test
in question in any case.

When running mirror_gre_bridge_1d_vlan tests on veth, several issues
cause spurious failures:
- vlan_ethtype should be ip, not ipv6 even in mirror-to-ip6gretap case,
because the overlay packet is still IPv4.
- Similarly ip_proto matches the innermost IP protocol, so can't be used
to filter out GRE packet. Drop the corresponding condition.
- Because the above fixes the filters to match in slow path as well,
they need to be made skip_hw so as not to double-count packets.

Add a reusable full test that toggles STP state of a given bridge port
and checks that the mirroring reacts appropriately. The test will be
used by bridge tests in follow-up patches.

Add full_test_span_gre_dir_vlan_ips() and full_test_span_gre_dir_vlan()
to support mirror-to-gre tests that involve VLAN.

For non-GRE mirroring tests, a functions along the lines of
do_test_span_gre_dir_ips() and test_span_gre_dir_ips() are necessary,
but such that they don't assume tunnels are involved. Extract the code
from mirror_gre_lib.sh to mirror_lib.sh and convert to just use a given
device without assuming it's named "h3-$tundev". Convert the two
above-mentioned functions to wrappers that pass along the correct device
name.
Add test_span_dir() and fail_test_span_dir() to round up the API for use
by following patches.

To simplify implementation of mirror-to-gretap tests, extend lib.sh with
several new functions that might potentially be useful more
broadly (although right now the mirroring tests will be the only
client).
Also add mirror_lib.sh with code useful for mirroring tests,
mirror_gre_lib.sh with code specifically useful for mirror-to-gretap
tests, and mirror_gre_topo.sh that primes a given test with a good
baseline topology that the test can then tweak to its liking.
