----------------------

./bin/trace
./src/H5.c
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
	Added a `scope' argument to H5Fflush() which should be either
	H5F_SCOPE_LOCAL or H5F_SCOPE_GLOBAL and determines which files
	are flushed (just the specified file or the entire virtual
	file).

./src/H5F.c
	Added reference counts to the H5F_t struct so we get the
	correct behavior between H5Funmount() and H5Fclose().

./src/H5O.c
	Fixed a memory leak that happens during error handling.

./test/cmpd_dset.c
./test/unlink.c
	Fixed a memory leak.

./test/mount.c
	Enabled the H5Fclose() test.
