"struct dbfile".  Add a database version field to that struct, and
remove the global database format variables.  This allows lyskomd
to have files in different versions open at the same time, so that
it can convert format X to format X+1 on the fly.  (This is more

format is now stored inside the dbfile struct.  Use
dbfile_open_read() instead of i_fopen(), and dbfile_delete()
instead of i_fclose().
* doc/lyskomd.texi (Modifying Stored Types): The default database
format is now defined in ram-io.c, and nowhere else.  It is
preferrable if lyskomd is able to convert an old format to a new
one after an upgrade.
* src/server/testsuite/test-l2g.c (main): Added a dbfile wrapper
