In this commit, I changed the way we calculate the string
representations, sig representations and the id's of methods. Before
that these fields would be recalculated everytime someone called .Sig()
.String() or .ID() on a method or an event.
Additionally this commit fixes issue #20856 as we assign names to inputs
with no name (input with name "" becomes "arg0")
The abi package already supports function overload by adding a suffix to the overloaded function name, but it uses the function name with suffix to calculate signature(both for the event and method).
This PR fixes it by adding a new field named RawName, which can be used to calcuate all signatures but use Name to distinguish different overloaded function.
