bigger files in sqlite

[krisoft]

Added ability to the android sql cache store to be able to contain bigger data files by saving them separately and saving a pointer into the database.

(This has been broken out from #153)

I'm quiet sure this use of available() method is wrong.

Take a look to this:
https://docs.oracle.com/javase/7/docs/api/java/io/FileInputStream.html#available()

You need something like:

   public static byte[] readAll(final InputStream is) throws IOException {
      final ByteArrayOutputStream result = new ByteArrayOutputStream();
      final byte[] buffer = new byte[16384];
      int read;
      while ((read = is.read(buffer, 0, buffer.length)) != -1) {
         result.write(buffer, 0, read);
      }
      result.flush();
      return result.toByteArray();
   }


   public static byte[] readAll(final File file) throws IOException {
      try (final FileInputStream is = new FileInputStream(file)) {
         return readAll(is);
      }
   }

Thank you very much @DiegoGomezDeck! Looks very much like you are right. I will consult with @DrakkLord and one of us will fix this.

@krisoft any advances in this PR?

It's in our worklog, but the feature on our side which depends on this got a lower priority. So it might take a while until we come around fixing the issues you so kindly pointed out for us. I hope that doesn't cause any trouble.
