// ResolveNameConflict returns the next available name for a given thing.
// This helper can be used for lots of purposes:
//
// - In solidity function overloading is supported, this function can fix
// the name conflicts of overloaded functions.
// - In golang binding generation, the parameter(in function, event, error,
// and struct definition) name will be converted to camelcase style which
// may eventually lead to name conflicts.
//
// Name conflicts are mostly resolved by adding number suffix.
// e.g. if the abi contains Methods send, send1
// ResolveNameConflict would return send2 for input send.
