by naming the transmit flags with an XMIT_ prefix.  Improved the names
of two other flags, got rid of the LIVE_FLAGS mask, and shortened the
flag storage in the flist struct (to save memory).

that the FLAG_TOP_DIR flag doesn't get set in the live data for a
non-directory (when it's used as a kluge to prevent a 0x00 byte being
sent over the wire for the flag data).

the struct hlink to have an index into the hlink_list[] array instead of
a head pointer.

the last item with FLAG_HLINK_EOL, and save off an index for our
master entry in the hlink_list[] array.  Added the hard_link_check()
function.

hard-linked files to send (when -H was specified, of course).  Moved
the call to do_hard_links() and the final directory-permissions scan
into generate_files() from recv_files().

scan from recv_files() into generate_files().

that we don't accidentally return a GID of 0 when we don't have the
permissions to set it.

front of rsync (not "a").

preservation by name (getting rid of the erroneous bit about the
--numeric-ids option being implied).

on a chroot daemon (it does not imply --numeric-ids).

make the chgrp test work on the NetBSD and OpenBSD systems where it is
failing.

the code is doing.  Also added a comment.

  our buffers (note that receive_file_entry() already does this).
- Changed f_name_to() to not do any length checking since it is
  now redundant.

overflowing elsewhere in the code.

- The "olddir" handling changed to accommodate the above, and to
  avoid using malloc()/free().
