 *           add_boot_rename_entry

 * Adds an entry to the registry that is loaded when windows boots and
 * checks if there are some files to be removed or renamed/moved.
 * <fn1> has to be valid and <fn2> may be NULL. If both pointers are
 * non-NULL then the file is moved, otherwise it is deleted.  The
 * entry of the registry key is always appended with two zero
 * terminated strings. If <fn2> is NULL then the second entry is
 * simply a single 0-byte. Otherwise the second filename goes
 * there. The entries are prepended with \??\ before the path and the
 * second filename gets also a '!' as the first character if
 * MOVEFILE_REPLACE_EXISTING is set. After the final string another
 * 0-byte follows to indicate the end of the strings.
 * i.e.:
 * \??\D:\test\file1[0]
 * !\??\D:\test\file1_renamed[0]
 * \??\D:\Test|delete[0]
 * [0]                        <- file is to be deleted, second string empty
 * \??\D:\test\file2[0]
 * !\??\D:\test\file2_renamed[0]
 * [0]                        <- indicates end of strings
