Support variadic methods

[adamcrume]

I have a method with a printf-like signature: func(string, ...interface{}). When this is mocked and set up with myMock.EXPECT().myFunc(gomock.Any()), then the function is actually called, Call.call panics because len(args) < ft.NumIn(). This is because the generated mock code builds args by flattening the variadic arguments and normal arguments into a single slice, but the reflection API expects the variadic arguments to be wrapped up in a slice.

I have a similar issue where I have a variadic signature:
func(context.Context, string, ...string)
and in one particular usage, I call it without providing any variadic args. I setup my expect call like:
mock.EXPECT().myFunc(gomock.Any(), gomock.Any())
but I get the error, "no matching expected call: ..." when it goes to execute the mocked function.

Any idea what the problem is with this?

Running into this as well and would be interested in any workarounds.
