A simple test for this new function has also been provided.

UTIL: move {files,selinux}.c under util directory files.c has at least one function that will be re-used for the new session provider that's about to be added. Also, a few other functions may be added and files.c seems the right place for those. selinux.c has been moved together with files.c as the latter takes advantage of some functions from the former and we do not want to always link agains the tools code. The public functions from files.c got a "sss_" prefix and it has been changed whenever they're used. Last but not least, all the places that included "tools/tools_util.h" due to the functions on files.c had this include removed (as they were already including "util/util.h".
