9c329a66d1 rework zero padding of rpc reply. 
- for READ procedure, don't send back more bytes than requested.
- don't have doubtful assumptions on mbuf chain structure.
- rename a function (nfsm_adj -> nfs_zeropad) to avoid confusion as
  the semantics of the function was changed.

bcf2e4f22f fix a problem in 'protected' case of writerpc. 
retransmitted mbufs can survive even after requests themselves
finished.  so, before unbusy pages, make sure that mbufs referring them
go away.

85d0052723 workaround for UBC limit. 
while our nfsd announces MAXBSIZE as wtmax for tcp,
VOP_GETPAGES of filesystems that uses genfs_getpages can't
handle >= MAX_READ_AHEAD(16) pages at once.
therefore, depending on PAGE_SIZE of the machine and file offset of
a read request, we can't VOP_GETPAGES the range at once.

a340c1b544 when a result of NFSv3 READLINK is too long for us, 
return ENAMETOOLONG rather than EBADRPC.
(it's our implementation limit, not protocol limit.)

9e95dcb696 Change some subordinate functions to take a "struct nfsnode" argument 
instead of "struct vnode". This saves a number of pointer dereferences;
it sums up to about half a kB for me. And it paves the way for future
fixes.
While cleaning up, eliminate a write-only member of "struct nfsreq"
and a pointless assignment in the NFS_V2_ONLY case.

80ecd573c0 PR/1796: John Kohl: statfs misbehaves under chrooted environments. 
- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
  and factored out some of the vfsop statfs() code to copy_statfs_info(). This
  fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.

043759a005 - do FILESYNC writes if we're freeing the page or the page doesn't 
belong to us.  otherwise, data will be lost on server crash.
- use b_bcount instead of b_bufsize to determine
  how many pages we should deal with.

based on a patch from Chuck Silvers.
