rlm_sql_log isn't really a SQL module, as it doesn't talk to a SQL
server. In fact, the module just feeds the radsqlrelay script and
it doesn't share any code with rlm_sql.

The module has it's own section because you're not supposed to
configure both rlm_sql and rlm_sql_log at the same time. However,
according to your SQL clean up idea, this section could be in a
separate file etc/raddb/sql/sql_log.conf instead of radiusd.conf.

The only problem with the rlm_sql_log method is that it doesn't
support the accounting_???_query_alt yet.

I'm unsure if we still need the "alt" queries: since MySQL 4.1 the
new syntax "INSERT ... ON DUPLICATE KEY UPDATE" allows to do something
similar with a single statement.
