/*  ydb functions used by loader
 */

// When the loader is created, it makes this call.
// For each dictionary to be loaded, replace old iname in directory
// with a newly generated iname.  This will also take a write lock
// on the directory entries.  The write lock will be released when
// the transaction of the loader is completed.
// If the transaction commits, the new inames are in place.
// If the transaction aborts, the old inames will be restored.
// The new inames are returned to the caller.  
// It is the caller's responsibility to free them.
// If "mark_as_loader" is true, then include a mark in the iname
// to indicate that the file is created by the ft loader.
// Return 0 on success (could fail if write lock not available).
