[svn-r1171] Changes since 19990330

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

./src/H5A.c
./src/H5D.c
	The `bkg' buffers are zeroed before calling the type
	conversion function. This fixes a problem where reading a file
	compound data structure into memory results in garbage between
	the members.

./src/H5I.c
	Fixed H5I_clear_group() so it removes entries even when a free
	callback is not registered. This fixes fixes an `infinite loop
	closing library' warning message.

./src/H5.c
	Added ellipses to the end of the infinite loop message.
