dmlib: Add Oracle dirty hack cleanup to recordset_to_menu() get_field_sql() and get_fieldset_sql()
...
This covers most (all?) the gaps in data retrieval except get_recordset_sql().
To tackle get_recordset_sql, where the actual data retrieval is done within
AdoDB, we would have to to wrap around AdoDB with a subclass, but that would
be dirty, dirty, dirtier.

Introducing sql_concat_join($sep, $array) helper

returns the SQL to do the equivalente of a join() or implode()
on the DB server. Watch the RDBMS work! ;-)

Introducing sql_concat() - and use it in sql_fullname()
...
sql_concat() is just a passthrough to $db->Concat() -- it doesn't
add any value, and I think the dispatching is somewhat expensive.
Just using $db->Concat() should be good enough, were it not for
consistency in our DM API.

Now using ADOdb standard transactions. Some day, we should switch to

Smart Transactions (http://phplens.com/adodb/tutorial.smart.transactions.html )

Now all the insert_record() and update_record() calls under

Oracle DB use the oracle_dirty_hack() function to transform
empty strings into something different ' ' in order to avoid
the problems with the empty=NULL stupid norm of Oracle.
With this change, Oracle installation works completely.
Now we need to implement everywhere the opposite hack: transforming
all those ' ' (1 whitespace) back to the '' (empty string). Working
on it now.
