  获得PushbackReader 如果是PushbackReader强转返回，否则新建
  
  Parameters:
  
  reader - 普通Reader
  
  pushBackSize - 推后的byte数
  
  Returns:
  
  PushbackReader
- toPushbackStream
  
  public static PushbackInputStream toPushbackStream(InputStream in, int pushBackSize)
  
  转换为PushbackInputStream 如果传入的输入流已经是PushbackInputStream，强转返回，否则新建一个
  
  Parameters:
  
  in - InputStream
  
  pushBackSize - 推后的byte数
  
  Returns:
  
  PushbackInputStream
- toAvailableStream
  
  public static InputStream toAvailableStream(InputStream in)
  将指定InputStream 转换为InputStream.available()方法可用的流。在Socket通信流中，服务端未返回数据情况下InputStream.available()方法始终为0 因此，在读取前需要调用InputStream.read()读取一个字节（未返回会阻塞），一旦读取到了，InputStream.available()方法就正常了。需要注意的是，在网络流中，是按照块来传输的，所以 InputStream.available() 读取到的并非最终长度，而是此次块的长度。此方法返回对象的规则为：
  
  FileInputStream 返回原对象，因为文件流的available方法本身可用
  
  其它InputStream 返回PushbackInputStream
  Parameters:
  
  in - 被转换的流
  
  Returns:
  
  转换后的流，可能为PushbackInputStream
