  Modified files:
    lib/libc/stdio       fseek.3 fseek.c stdio.c 
  Log:
  1) Disallow negative seek as POSIX require for fseek{o} (but not for lseek):
  
  "[EINVAL] ... The resulting file-position indicator would be set to a
  negative value."
  
  Moreover, in real life negative seek in stdio cause EOF indicator cleared
  and not set again forever even if EOF returned.
  
  2) Catch few possible off_t overflows.
