/**
 * @TODO There is plugin.h and also sql_plugin.h.  Ostensibly,
 * it seems that the two files exist so that plugin.h can provide an
 * external API for plugin developers and sql_plugin.h will provide
 * and internal server API for dealing with those plugins.
 *
 * However, there are parts of plugin.h marked "INTERNAL USE ONLY" which
 * seems to contradict the above...
 *
 * Let's figure out a better way of dividing the public and internal API
 * and name the files more appropriately.
 *
 * Also, less #defines, more enums and bitmaps...
