Rsync was showing the full destination path, which was confusing because
nothing is created at that path and was especially bogus in combination
with the source name of a solo file.

- The receiver now sends keep-alive messages to the generator
when it is actively doing work and hasn't sent anything
recently. This ensures that the generator won't timeout
if the receiver is working hard.
- The perform_io() code has improved keep-alive participation.
- Allow the sender to send some keep-alive messages, which
ensures that if it is in a lull, it can probe the socket.
The receiving side also switches timeout handling from the receiver to
the generator, which obviates the need for the sender to send any
keep-alive messages at all (for protocol 31 and beyond). Given this
setup, all keep-alive messages are now sent as empty MSG_DATA messages,
with MSG_NOOP messages only being understood and (when necessary) acted
upon to forward a keep-alive event to an older receiver. This is both
safer and more compatible with older versions.
If a symlink, device, special-file, or hard-linked file is replacing
an existing non-directory, the new file is created using a temporary
filename and then renamed into place. Also changed the handling of
a cluster of hard-linked symlinks/devices/special-files to always
ensure the first item in the cluster is correct, since it doesn't
really save any significant work to try to find an existing correct
item later in the cluster to link with.
Since the value is not needed, protocol 31 no longer sends it, while
older protocols are optimized so the sender just sends a valid rdev
value as efficiently as possible. The receiver no longer caches an
rdev value for special files, and the generator will always pass a 0
rdev value to do_mknod() for special files. Fixes bug #6280.
- Changed get_backup_name() to verify the backup path, and make any
missing directories. This avoids accidental use of a symlink as a dir
in a backup path, and gets rid of any other non-dirs that are in the
way. It also avoids the need for various operations to retry after
calling make_bak_dir(), simplifying several pices of code.
- Changed create_directory_path() to make_path(), giving it flags that
lets the caller decide if it should skip a leading slash or drop the
trailing filename.
- Mention when we create the backup directory, so the user is not caught
unaware when rsync uses a directory they didn't expect.
- Got rid of some dir-moving backup code that is not used.
- Added a little more backup-debug output.
- Implement --ignore-missing-args.
- In the absence of --*-missing-args, a missing source arg is an
FERROR_XFER, but doesn't need to be an IOERR_GENERAL.
- Revise the man page.
This fixes an issue with -K noticed by eric casteleijn, avoids some
inconsistent itemizing when a file/dir is replaced by a dir/file,
and removes a now-obsolete chunk of code from make_file().
- Mention how many files were created (protocol >= 29).
- Mention how many files were deleted (new in protocol 31).
- Follow the file-count, created-count, and deleted-count
with a break-out list of each count by type.
