feat(wip): r/aib/ibc

[tbruyelle]

The r/aib/ibc/core realm provides the expected functions, CreateClient, RegisterCounterParty, UpdateClient, UpgradeClient , SendPacket , RecvPacket, Acknowlegdment and Timeout. Most of them are TODOs for now, but they are callable.

The r/aib/ibc/apps realm provides applications that implements the p/aib/ibc/app.IBCApp interface. Such apps must be registered into the core module using the core.RegisterApp() function.

To run a gno node, clone this repo, checkout the aib/feat/ibc branch, run make install and finally run gnodev inside the folder. This will pop a node and you should be able to see the functions at http://localhost:8888/r/aib/ibc/core$help. This help page also gives instructions to call the functions, but only with MsgCall. This kind of call won't work with most of the IBC functions, because they use complex args. See the README for detailed call instructions.

Once created, clients are visible here http://localhost:8888/r/aib/ibc/core:clients

Moved everything in a separate repo since it became too big to be reviewed, and also because I can point to a fork of gno with the required changes:
