Added support for MOVEFILE_DELAY_UNTIL_REBOOT, based on Wine code by
Gerhard W. Gruber and others. Still requires smss to check the key.

*
+ * 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 registrykey 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
+ *
+ * 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
