Dmitriy Philippov (shedon@mail.ru):

Browse source 
- The MOVEFILE_DELAY_UNTIL_REBOOT flag is incorrect processed in the MoveFileWithProgressW function.
- The add_boot_rename_entry function contains too many bugs, it crashes when
deleting operation is performed, it does not save old entry in registry, etc...

Fixes are based on the testing application located in reactos/base/application/testsets/smss/movefile
