fixes lot of memory leaks and other bugs.

Take care to this change:
The url columns in the mysql database help tables were too short to hold some of the URLs in the help content.
For upgrades, mysql_upgrade does not update the columns. Modify them manually using these statements:
ALTER TABLE mysql.help_category MODIFY url TEXT NOT NULL;
ALTER TABLE mysql.help_topic MODIFY url TEXT NOT NULL;
