work in progress, cleaned up the directories and split them up into folder which make more sense, Still need to compile libvitaboy and all the tools

+ * SPI plans have two states: saved or unsaved.
+ *
+ * For an unsaved plan, the _SPI_plan struct and all its subsidiary data are in
+ * a dedicated memory context identified by plancxt.  An unsaved plan is good
+ * at most for the current transaction, since the locks that protect it from
+ * schema changes will be lost at end of transaction.  Hence the plancxt is
+ * always a transient one.
+ *
+ * For a saved plan, the _SPI_plan struct and the argument type array are in
+ * the plancxt (which can be really small).  All the other subsidiary state
+ * is in plancache entries identified by plancache_list (note: the list cells
+ * themselves are in plancxt).	We rely on plancache.c to keep the cache
+ * entries up-to-date as needed.  The plancxt is a child of CacheMemoryContext
+ * since it should persist until explicitly destroyed.
+ *
+ * To avoid redundant coding, the representation of unsaved plans matches
+ * that of saved plans, ie, plancache_list is a list of CachedPlanSource
+ * structs which in turn point to CachedPlan structs.  However, in an unsaved
+ * plan all these structs are just created by spi.c and are not known to
+ * plancache.c.  We don't try very hard to make all their fields valid,
+ * only the ones spi.c actually uses.
+ *
+ * Note: if the original query string contained only whitespace and comments,
+ * the plancache_list will be NIL and so there is no place to store the
+ * query string.  We don't care about that, but we do care about the
+ * argument type array, which is why it's seemingly-redundantly stored.
