IntStream's size's documentation includes EOF but it shouldn't based on implementation

[asztrikx]

This affects multiple targets but for example in C# target:

IIntstream defines Size in documentation as the length of stream + 1 (EOF):
Returns the total number of symbols in the stream, including a single EOF

However for example BaseInputCharStream defines Size as n

where n is set to input's size only e.g. in AntlrInputStream

this.n = input.Length;

I tested this with the following code:

var input = "test";
var lexer = new ExampleLexer(new AntlrInputStream(input));
var expected = input.Length + 1;
var got = lexer.InputStream.Size; // IIntstream
Trace.Assert(expected == got, $"Expected: {expected}, got: {got}");
	// Expected: 5, got: 4

I can confirm – I replicated this in Java, and got the same error.
