fuse: allow entering username and password via stdin

Browse Source 
- when either username or password are not specified via commandline
   arguments or configuration file, ask them on standard input
 - unify function to read username and password
 - move function to read username and password from mfshell to
   utils/strings.c
 - remove commented cruft from utils/strings.c
