[KERNEL32] Minor code style changes + add documentation for BasepMoveFileDelayed().
+ cut the too long lines; don't hardcode types in sizeofs; correctly specify
COPY_FILE_FAIL_IF_EXISTS flag.

+ * @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
+ *
