added nfs41_abs_path symlink to struct open_upcall_args. we can't write the symlink target back to args->path anymore, since it's a pointer into the upcall buffer

because we no longer have to convert strings from unicode, we can avoid copying them out of the upcall buffer

moved the FileSystemName definition back down to the kernel, so the daemon is no longer responsible for setting it. the driver uses the string length to calculate the buffer size needed for NFS41_V_NET_ROOT_EXTENSION.FsAttrs, and copies in the FileSystemName after the first successful volume attributes upcall

added FILE_FS_ATTRIBUTE_INFORMATION and FileSystemAttributes flags to from_kernel.h
queries case_preserving, case_insensitive attributes to fill in FileSystemAttributes, and uses #defines from nfs41_const.h for MaximumComponentNameLength and FileSystemName
