/**
 * @brief
 * Adds an entry in the "PendingFileRenameOperations" registry value, that is
 * parsed at boot-time by SMSS.EXE to check whether there are some files to be
 * renamed/moved or deleted.
 *
 * @param[in]   ExistingPath
 * Full NT path to the file to rename/move or delete.
 *
 * @param[in]   NewPath
 * Full NT path to the moved/renamed file; or an empty string if the file is
 * to be deleted.
 *
 * @param[in]   KeyId
 * Selects an alternate "PendingFileRenameOperationsXXX" registry value.
 *
 * @param[in]   CreateIfNotFound
 * TRUE if the file needs to be created if it does not already exist,
 * FALSE if not.
 *
 * @remark
 * If both ExistingPath and NewPath strings are non-empty, the file is moved,
 * otherwise it is deleted.
 *
 * @note
 * The registry value is a list of NULL-terminated strings, which is itself
 * terminated with an empty NULL-terminated string (single 0-byte).
 * When a new entry is added, if NewPath is empty, then the second entry is
 * simply a single NULL. Otherwise the second file path goes there.
 * Each path is in NT format (e.g. path prepended with \??\) and the second
 * file path gets also a '!' as the first character if MOVEFILE_REPLACE_EXISTING
 * is specified.
 *
 * Examples:
 *
 * \??\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
 *
 * or:
 *
 * \??\D:\test\file1[0]
 * !\??\D:\test\file1_renamed[0]
 * \??\D:\test\delete[0]
 * [0]                        <- file is to be deleted, second string empty
 * [0]                        <- indicates end of strings
