There are two aspects:
1) undoing magic quotes (if it's being used).
This must be done for all GET and POST string inputs.
It is now done automatically by get_str() and post_str().
The places that refer to $_GET and $_POST directly
must do it themselves using undo_magic_quotes().
2) Escaping user-supplied strings before using them in DB queries.
This is done by process_user_text()
(which should be renamed db_escape_string()).
The new principle:
call process_user_text() in the function that does the DB query
(not at any higher level).

1) it's not correct to apply stripslashes() to all form input.
That should be done only if magic quotes is on.
I fixed this by adding a function undo_magic_quotes()
that does the right thing.
2) There's no reason to strip backslashes from user-supplied text
(forum titles and bodies, private messages, passwords etc.)
I'm not sure why this was being done.
It prevented messages from containing backslashes.

needs to be parsed from a single place, eg config.xml, and used
consistently in both PHP and client-side ops.
