Add support of CLSAG signature algorithm

[grydz]

The Monero blockchain will change the signature algorithm from MLSAG to CLSAG in the next hardforks (v13 and v14). This PR adds necessary changes in the Monero app to interact with the future release of the Monero client 0.17.0.0:

• Add support of CLSAG signature (INS_CLSAG)
• Update to protocol v4 for support of both MLSAG and CLSAG
• Update InProofv1 to InProofv2

[selsta]

Any estimate when CLSAG / v0.17 supporting version will be released? We plan to release v0.17 on 2020-09-17, it would be good to have the update available until then.

[selsta]

ping @grydz, when will the app be available? We will release v0.17 today.

[FabriceDautriat]

@selsta The Monero-dev app is available once you enable the developer mode in Ledger Live settings.

The version of the app is v1.7.0.

As soon as the Monero GUI is released (based on 0.17), the public Monero app will be updated to 1.7.0.

Please make sure to ping me when it's the case 🙏

[selsta]

Thank you for the update, I will comment once the GUI is released :)

FWIW I tested it on testnet and it did not seem to work.

Will test on stagenet now.

[selsta]

Stagenet and mainnet still seem to work fine so there is a bit of time (until 2020-10-17) to get this issue resolved.

[FabriceDautriat]

@grydz can you please take a look ?

[grydz]

Monero application 1.7.1 is available in developer mode and should fix the problem.

[grydz]

Well, Monero application 1.7.2 should fix the problem!

[selsta]

@grydz v0.17 GUI is now released.
