Apply `AccessMask.SYNCHRONIZE` and `CreateOptions.FILE_SYNCHRONOUS_IO_NONALERT` to all `fileStore.CreateFile` calls to ensure synchrony on operations.

[Jo0]

Changed

• Apply AccessMask.SYNCHRONIZE and CreateOptions.FILE_SYNCHRONOUS_IO_NONALERT to all fileStore.CreateFile calls to ensure synchrony on operations.
  • Left retry logic in place for now, STATUS_PENDING seems to no longer occur
• Set explicit ShareAccess.Read and ShareAccess.Write to fileStore.CreateFile calls for better Samba compabitility.
  • Windows Share ACL was fine with how we were defining ShareAccess on calls. Samba shares seem to be picky about it.
• Remove calls to ToUniversalTime() from Set*Time in SMBFile
• Add tests in FileTests for IFile.Open operations

  Fixed

• Fix Set*TimeUtc calls to use ToUniversalTime() in SMBFile
• Match DirectoryName behavior in SMBFIleInfo with base.FileInfo
