- Got rid of some unneeded blocking_io value twiddling.
- Send --use-qsort to the server if it was specified.

  call it when the server is in setup_protocol().  The function sets
  allow_inc_recurse to 0 if some options won't allow us to support
  an incremental-recursive transfer.
- The server now checks for an 'i' in the -e option from the client
  and zeros out allow_inc_recurse if not found.
- The server reports its inc_recurse determination back to the client.
- The client sets inc_recurse based on the value it gets from the server.

  is going to run in inc_recurse mode or not.
- Verify that the options we received (as a server or as a batch-reader)
  are compatible with the requested inc_recurse mode.

that likes to point out an "if (...)" with a semicolon after it).

no need to comment if a RSYNC_PASSWORD environment variable is set.

- Check the FLAG_IMPLIED_DIR flag to find implied dirs.
- Expect flagged implied dirs for all protocol 30 transfers.

- Use the new *_CONTENT_DIR flag names (was *_XFER_DIR).
- Send implied dirs with XMIT_TOP_DIR | XMIT_NO_CONTENT_DIR.
- All protocol 30 transfers send flagged implied dirs.

- Changed the *_XFER_DIR flags to *_CONTENT_DIR flags.
- Increment SUBPROTOCOL_VERSION.

is a local_server copy, and so that arg-parsing code doesn't interfere
with the sending of a remote charset value.

to ignore implied dirs that are actually present in the file list
when inc_recurse is active and --no-implied-dirs was specified.

- Simplified the flag setting in send1extra since we know that
  recurse is set.
- Make sure that FLAG_XFER_DIR is unset for a non-dot-dir when
  recurse is not set.
- The --relative code wasn't setting is_dot_dir enough.
