LF in getProgramInfoLog #50

Description

@AlexVestin

A (very) minor issue, but there is a linefeed in the getProgramInfoLog after it has been linked
Edit: Also when created it should yield a 0 length string, but instead there is a 1 length string,
with a null char. So maybe double null characters have been added?

const nodeGles = require("node-gles");
const gl = nodeGles.binding.createWebGLRenderingContext();
var program = gl.createProgram();
let log = gl.getProgramInfoLog(program);

console.log(log.length, log.charCodeAt(0));

const vs = `// Vertex Shader
void main() {
  gl_Position = vec4(1.);
}`

const fs = `// Fragment shader
void main() {
  gl_FragColor = vec4(1.);
}`

function loadShader(gl, type, source) {
    const shader = gl.createShader(type);  
    gl.shaderSource(shader, source);  
    gl.compileShader(shader);  
    if (!gl.getShaderParameter(shader, gl.COMPILE_STATUS)) {
      gl.deleteShader(shader);
      return null;
    }
    return shader;
}

gl.attachShader(program, loadShader(gl, gl.VERTEX_SHADER, vs));
gl.attachShader(program, loadShader(gl, gl.FRAGMENT_SHADER, fs));
gl.linkProgram(program);

if (!gl.getProgramParameter(program, gl.LINK_STATUS)) {
    console.error('Unable to initialize the shader program: ' + gl.getProgramInfoLog(program));
}

log = gl.getProgramInfoLog(program);
console.log(log.length, log.charCodeAt(0))

yields

1 0
2 10

Which makes checks for if (log === "") fail
