In the internal function sepol_av_to_string(), use a dynamically allocated buffer for the permission names of an access vector instead of a fixed static buffer to support very long permission names. Update the internal users of sepol_av_to_string() to free the buffer. The exported function sepol_perm_to_string() is just a wrapper to the internal function. To avoid changing the behavior of this function, use a static buffer and copy the resulting string from the internal function. If the string is too long for the buffer or there was an error in creating the string, return a string indicating the error. All of the changes to the internal function and users was the work of Christian Göttsche <cgzones@googlemail.com>.
