when deleting a whole l2vpn context in ldpd which also had pseudowires
in it, we were first deleting the l2vpn with a 'no l2vpn XXX' command,
and then adding it again by running 'l2vpn XXX\n no member pseudowire YYY'
which obviously was not needed. As a result the l2vpn would be reinstated.

bgpd: identify passive connections in JSON summary
When using non JSON output, passive connections are marked with:
BGP state = Active (passive)
However, such an information is not available in JSON output. This
commit adds that. It also adds "Active (NSF passive)" flag, like the
regular output.

tests: ignore Windows vs Unix style newlines
Within unit tests the output of vtysh commands is compared to hand
made reference files. For some reason the output of those vtysh
commands contains Windows Style newlines which results in error
outputs which make it hard to identify this problem.
Since there seems to be no benefit in checking those newlines
anyway this commit just normalizes them.

ospfd: reset mpls-te prior to ospf router removal
This commits attempts to fix a problem that occurs when mpls-te gets
removed from ospfd config. Mpls-te has an inter-as option, which can be
set to Off/Area/AS. Whenever the inter-as takes "Area" or "AS" as a
value, this value will not be cleaned after removing mpls-te or after
removing the ospf router. Therefore, if mpls-te is configured with
inter-as AS or Area and we remove mpls-te or the ospf router, the
inter-as will still preserve its value; therefore, next time mpls-te is
enabled, it will automatically inherits the previous inter-as value
(either Area or AS). This leads to wrong configuration, which can be a
problem for frr_reload.py.
The commits forces mpls-te to reset inter-as to Off before it mpls-te
gets removed from the configuration and before the ospf router gets
removed.
