[LTP] [RFC PATCH v7 0/7] Simplify network setup + fix some network stress tests

[Petr Vorel <pvorel@suse.cz>]

Hi,

as it might be uncomfortable to see patches on mailing list, you can also see
them on github: https://github.com/pevik/ltp/tree/tst_net_vars.v7

Changes v6->v7:
* I more radically cleanup IPV4 multicast and route scripts. Also changed a bit
  interfaces tests. I spent a lot of time with cleanup and testing. Cleaned
  scripts should work under SSH and netns.
* I split tst_net_vars into 3 tools. This was necessary to have reading of
* rtnetlink on rhost.

TODO:
* Add more test links for netns (for route4-change-if).
* Fix also IPv6 scripts.
