This patchset adds a test for ECMP and weighted ECMP between two GRE

In patches #1 and #2, the function multipath_eval() is first moved from
router_multipath.sh to lib.sh for ease of reuse, and then fixed up.

In patch #3, the function tc_rule_stats_get() is parameterized to be
useful for egress rules as well.

In patch #4, a new function __simple_if_init() is extracted from
simple_if_init(). This covers the logic that needs to be done for the
usual interface: VRF migration, upping and installation of IP addresses.

Patch #5 then adds the test itself.

Additionally in patch #6, a requirement to add diagrams to selftests is

Changes from v1 to v2:
- Add a diagram to patch #5.
- In patch #2, don't use | as line continuation character. Instead use
  the sequence \, newline, | consistently.
- Likewise in patch #3.
- Add patch #6.
