symlink: nfs41_symlink_follow() for readdir and open

Browse source 
added nfs41_file_info.symlink_dir to replace readdir's info.cansettime hack.  when nfs_file_info_to_attributes() finds info.type==NF4LNK, it adds the FILE_ATTRIBUTE_DIRECTORY flag if info.symlink_dir is set

renamed nfs41_symlink_follow() to nfs41_symlink_target()
generalized lookup_symlink() into nfs41_symlink_follow(), which is called by readdir and open (also avoids an extra lookup)

added queries for symlink target type when doing normal GETATTRs (getattr.c) and opens with OPEN_REPARSE_POINT set (open.c)
