VeraCrypt 1.25 Update 4

What's new in this version:

- Speed optimization of Streebog
- Update translations
- Add support for Windows on ARM64 (e.g. Microsoft Surface Pro X) but system encryption not yet supported.
- Add MSI installer for silent mode deployment (ACCEPTLICENSE=YES must be set in msiexec command line).
- For now, MSI installer cannot be used if system partition is encrypted with VeraCrypt
- MSI installer requires Windows 10 or newer
- Drop support of Windows Vista, Windows 7, Windows 8 and Windows 8.1 because of new requirement for driver code signing.
- Reduce time of mount when PRF auto-detection is selected.
- Fix potential memory corruption in driver caused by integer overflow in IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES (reported by Ilja van Sprundel).
- Replace insecure wcscpy/wcscat/strcpy runtime functions with secure equivalents.

Changes to EFI bootloader:
- Fix memory leak in some cases caused by wrong check of pointer for calling MEM_FREE
- Clear bootParams variable that may contain sensitive information when halting the system in case of fatal error
- Add option "KeyboardInputDelay" in DcsProp to control the minimum delay supported between two key strokes

- Try to workaround Windows Feature Updates issues with system encryption by fixing of bootloader and SetupConfig.ini when system resumes or when session is opened/unlocked
- Fix failure to load local HTML documentation if application running with administrative privileges
- Fix freeze when password dialog displayed in secure desktop and try to access token keyfiles protected by PIN
- Fix failure to launch keyfile generator in secure desktop mode
- Block Windows from resizing system partition if it is encrypted
- Add keyboard shortcut to "TrueCrypt mode" in the mount dialog.
