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.

- 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.
- Backups do not interfere with an atomic update (when possible).
- Backing up a file will remove a directory that is in the way
and visa versa.
- Unify the backup-dir and non-backup-dir code in backup.c.
- Improved the backup tests a little bit.
were moved out of file_struct into an optional member-var setup.
- Renamed and reorganized the FLAG_* defines.
- Use NDX_DONE instead of a literal -1 when sending/checking the
end-of-phase index value.
- Standardized the format of the opening comment, including adding a
brief description of what's in the file for those that lacked it.
- Added some missing copyright lines.
- Some minor whitespace tweaks (in a few of the files).
need to remove any old symlink/device/file to create the backup.
Also fixed a couple minor logic errors in the handling of symlinks
and devices. NOTE: the code still doesn't handle the changing of
a name from a dir to a non-dir or visa versa (which is a very old
deficiency in the code).
