No error message when opening a non-existing file

[Former user]

This can be reproduced by compiling and running the cube demo changing the final simulation time to, e.g., 1 as described in this issue. When the dual solve starts, dolfin will try to open a non-existing file based on the value of the variable no_samples. Instead of reporting that the file does not exist, dolfin will eventually crash at the file header check.

Implementing file access control in src/io/BinaryFile.cpp

Fixed with commit 49753c0. We might want to consider implementing similar functionalities for other file formats as well, i.e. not inside /io/BinaryFile.cpp.
