The DOCS option dumped the critical dba directory along with non-docs
directories scripts and config into DOCSDIR, which resulted in a broken

Reorganize the port to put dba and scripts in DATADIR, and config in
EXAMPLESDIR and add the EXAMPLES option. While here, use the @sample
keyword, clean up @dirrm, and tweak a bit.
