Add Nik's torture tests as a new set to stress the replace and cleanup
paths.
Torture test created by Nikolay Aleksandrov and then I adapted to
selftest and added IPv6 version.

Add a couple large ecmp group nexthop selftests to cover
the remnant fixed by d69100b8ee.
The tests create 100 x32 ecmp groups of ipv4 and ipv6 and then
dump them. On kernels without the fix, they will fail due
to data remnant during the dump.

The 'pref medium' attribute was moved in iproute2 to be near the prefix
which is where it applies versus after the last nexthop. The nexthop
tests were updated to drop the string from route checking, but it crept
in again with the compat tests.

Add nodad when adding IPv6 addresses and remove the sleep.
A recent change to iproute2 moved the 'pref medium' to the prefix
(where it belongs). Change the expected route check to strip
'pref medium' to be compatible with old and new iproute2.
Add IPv4 runtime test with an IPv6 address as the gateway in
the default route.

Add some test cases to allow the fib_nexthops.sh test code
to test the flushing of nexthops based upon the proto passed
in upon creation of the nexthop group.

Cleanups of the tests in fib_nexthops.sh
1. Several tests noted unexpected route output, but the
discrepancy was not showing in the summary output and
overlooked in the verbose output. Add a WARNING message
to the summary output to make it clear a test is not showing
expected output.
2. Several check_* calls are missing extra data like scope and metric
causing mismatches when the nexthops or routes are correct - some of
them are a side effect of the evolving iproute2 command. Update the
data to the expected output.
3. Several check_routes are checking for the wrong nexthop data,
most likely a copy-paste-update error.
4. A couple of tests were re-using a nexthop id that already existed.
Fix those to use a new id.
