Get dynamic IBC working again

[michaelfig]

Closes #2067

Works with cosmos/relayer#428

We need this to release agorictest-5.

[dckc]

I see...

I'm happy to say that after cosmos/relayer#428 , Agoric's dIBC works again (cosmos-sdk v0.41.0)!

How can I reproduce the sense in which this "works"?

i.e. how can I verify that #2067 is fixed?

I'll add a document with my usage notes explaining how to test.

@dckc, this should be R4R. See README-dibc.md in this PR for testing instructions.

It seems to work but for the last step:

ag-ibc/packages/cosmic-swingset/relayer$ rly tx xfer ibc1 ibc0 10000n0token true $(rly keys show ibc0 testkey) -ppath-2
Error: accepts 4 arg(s), received 5

what clue am I missing?

[dckc]

might be worth noting that building the relayer currently requires git with --show-current support, which only appeared in git 2.22.0 .

That is: while building the relayer , I got:

error: unknown option `--show-current'

Evidently --show-current requires git 2.22.0, but Ubuntu 18.04 only supplies 2.17.1.

I used nix-shell -p git to get 2.29.2.
