Windows: add /nosizecheck switch to VeraCrypt Format that allows disabling check on file container size against available free space on target disk. This enables to workaround a bug in Microsoft Distributed File System (DFS) that report wrong free disk space (https://support.microsoft.com/en-us/help/177127/incorrect-disk-free-space-information-for-a-dfs-client-share)
