we were previously only verifying that the server didn't reboot between WRITEs. COMMIT returns a verifier that needs to be checked as well

added 2011 year to the copyright line
added authors info to the license
added UofM license to libtirpc files that we modified
(but i probably missed some)
previously we'd query owner and group file attributes on all getattrs and
storing that in nfs41_file_info structure which was caused a problem for
readdirs.
combined nfs41_open() and nfs41_open_reclaim() into nfs41_rpc_open() by factoring out the open_claim4 argument. new function nfs41_open() in open.c deals with the nfs41_open_state, adding it to the client's list, and handles any delegations granted
added xdr for OPEN CLAIM types CLAIM_DELEGATE_CUR, CLAIM_DELEG_CUR_FH, CLAIM_DELEGATE_PREV, CLAIM_DELEG_PREV_FH (the _FH types are new to 4.1, and not supported by linux server)

acls are lists of arbitrary length, so xdr_array() is used to allocate the array
during decode. because this memory is allocated by the tirpc library, it needs
to be freed there as well; added function nfsacl41_free() to do this with XDR_F

fixes a memory leak that occurs when a readdir loop doesn't complete, since the cookie was only freed on the last readdir upcall. by storing the cookie with nfs41_open_state, we can avoid passing the cookie to the driver and back, and not worry about having to free it separately

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)

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
