-lock support moved from dba_flatfile.c to dba.c
-flatfile, cdb, cdb_make use locking now
#locking is blocking per default use 'rt', 'wt', ct' or 'nt' for non blocking alias
#test access to a database file.
#locking uses flock() which will be emulated or warned if that is not eally
#possible in ext/standard/flock_compat.c
