script to update DB object comments

script to update DB object comments

New script, update-db-comments.sh, to be run as part of upgrades
to refresh comments on database schema objects.  Usage is:

  update-db-comments.sh db-host db-port db-name db-user db-pass

The helper script grab-db-comment.pl is what actually parses out
the comment statements.

To avoid repetition, the list of default SQL scripts to use when
initializing an Evergreen database has been moved to a new file
called sql_file_manifest.
