The current key update function allows following bad values. 1. Zero threshold value, when renders multisig contract without any additional security. 2. Threshold value that is larger than the number of keys, which locks out the multisig contract completely and renders it useless. This change adds sanity checks that rejects bad threshold/key pairs as listed above.

IMO these checks should be done off-chain. The Tezos client already check this: https://gitlab.com/tezos/tezos/-/blob/master/src/proto_006_PsCARTHA/lib_client/client_proto_multisig.ml#L691. |

Sanity check new threshold/key pair during key updates
The current key update function allows following bad values for new threshold/key pair.
Threshold value is Zero, which renders multisig contract without any
additional security.
Threshold value is larger than the number of keys, which locks
out the multisig contract completely and renders it useless. This could even lock the target contract where the multisig contract acts as an administrator/owner.
This change adds sanity checks that rejects bad threshold/key pairs as
listed above.
