./src/H5Bprivate.h The B-tree K value comes from a combination of the B-tree subclass and the file. ./src/H5C.c ./src/H5F.c ./src/hdf5lims.h ./src/hdf5type.h Removed the B-tree size parameter and added an array of B-tree K values. Also added symbol table node K value. ./src/H5Eprivate.h ./src/H5Eproto.h Added H5E_LINK for errors involving link counts. ./src/H5G.c Inserting something into a directory with H5G_insert() increments the link count in the object header. The root object should always have a link count of at least 1. ./src/H5Gnode.c ./src/H5Gprivate.h The symbol table node K value comes from the file instead of being a constant. ./src/H5Olink.c Added an assert(), fixed a hard-link bug.
