driver handles FSCTL_SET_REPARSE_POINT by sending a symlink set upcall
daemon handles symlink set upcall by calling nfs41_create()

new NFS41_SYMLINK upcall and associated data in nfs41_updowncall_entry.u.Symlink
supports both setting and querying the symlink target. if Symlink.set is TRUE, Symlink.target is marshalled into the upcall. if Symlink.set is FALSE, Symlink.target is read from the downcall

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

marshall_unicode_as_ansi() calls RtlUnicodeStringToAnsiString() to convert the string directly into the upcall buffer

on ERROR_REPARSE, nfs41_Create() generates an absolute path for the symlink target using the format "DeviceName+NetRootName+symlink", and calls RxPrepareToReparseSymbolicLink()

on last_error == ERROR_REPARSE, the daemon converts args->path back to wchar and passes it down to the driver

caused memory leaks of nfs41_open_state. we have the FileDispositionInformation upcall for exactly this, so there's no need to complicate the close code path

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

adds support for mounting with 'net use' and 'Map Network Drive'
if we don't have extended attributes on mount (i.e. not using nfs_mount), don't fail! instead, use SrvName=SrvCallName and MntPt=""
updated nfs41_MountConfig_InitDefaults() to initialize SrvName and MntPt with Length=0

removed the Config field from NFS41_NETROOT_EXTENSION and NFS41_V_NET_ROOT_EXTENSION and made it local to CreateVNetRoot(), as that's the only place it's accessed and we no longer rely on storing Config.Initialized with the NET_ROOT

was previously setting pNetRootContext->session to INVALID_HANDLE_VALUE on error, and required checking for both that and NULL. since it starts initialized to NULL, keep it that way

was doing a memcpy from entry->u.QueryFile.buf to RxContext->Info.Buffer, even though we set entry->u.QueryFile.buf = RxContext->Info.Buffer
