New Signature interface available in the top level types package.
auth.StdSignature implements such interface. User defined auth
module can now define their own custom signature types.
Work carried out in the context of the following issues:
- #4488
- #4487
* Add ValidateBasic to Tx interface
* Update BaseApp unit tests
* Add missing return in ValidateBasic
* Update ValidateBasic to use IsNotNegative
* Add pending log entry
* Add unit test TestTxValidateBasic
* Fix broken lint regression
* Add sig count check to validation
* Add test case to TestTxValidateBasic
This is to facillitate ease of implementing #1406. (Tags for messages
could then be added dynamically)
Ultimately once we make the router support hiearchical routing, (#770)
we can then remove the name field and just the parse info for tags from that.
Until then, we can parse the tag name as
`fmt.Sprintf("%s %s", msg.Type(), msg.Name())`
- call MustSortJSON before return JSON bytes to guarantee alphabetic
ordering
- moved SortJSON and MustSortJSON to types package to avoid cyclic
package dep
This method is an unneccessary requirement on Tx. Auth casts the Tx
to StdTx, so the memo can be obtained in previous usecases from
StdTx. This also makes it more clear for when something is
implementing StdTx vs Tx.
