[svn-r355] Changes since 19980417

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

This checkin completes the compression stuff almost two weeks ahead of
schedule.  It should now all be working and documented.

./Makefile.in
./config/commence.in
	A distclean causes the distribution makefile to be copied to
	Makefile again.

./src/H5D.c
	Opening a compressed dataset now works properly.

./src/H5P.c
./src/H5Ppublic.h
	The H5Pset_compression() and H5Pget_compression() now work as
	documented.

./src/H5T.c
	Fixed a bug that causes the library to crash sometimes if
	debugging is turned on for the `t' package.

./src/H5Z.c
	Fixed a bug where the number of bytes attributed to
	compression overruns was too low in the debugging output.

./test/dsets.c
	More compression tests: reading of uninitialized data, opening
	an existing dataset and reading it, partial I/O which isn't
	aligned on chunk boundaries, and use of application-defined
	compression methods.

./MANIFEST
	Removed ./test/dspace.c.
