Windows 8 and later can create NFS symlinks (within reparse points)
which we were assuming were normal NTFS symlinks and thus reporting
corrupt paths for. Add check for reparse points to make sure that
they really are normal symlinks before we try to parse the pathname.
We also should not be parsing other types of reparse points (DFS
junctions etc) as if they were a symlink so return EOPNOTSUPP
on those. Also fix endian errors (we were not parsing symlink
lengths as little endian).
This fixes commit d244bf2dfb
which implemented follow link for non-Unix CIFS mounts

MS-SMB2 Section 2.2.31 lists fsctls. Update our list of valid
cifs/smb2/smb3 fsctls and some related structs
based on more recent version of docs. Additional detail on
less common ones can be found in MS-FSCC section 2.3.
CopyChunk (server side copy, ie refcopy) will depend on a few
of these

There are about 60 fsctl calls which Windows claims would be able
to be sent remotely and handled by the server. This adds the #defines
for them. A few of them look immediately useful, but need to also
add the structure definitions for them so they can be sent as SMBs.
