[svn-r569] Changes since 19980731

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

./bin/release
	Added ./Makefile to the distribution again -- it got lost in
	the changes last week although it isn't all that important a
	file since it gets clobbered by configure anyway.

./test/dsets.c
./tools/h5ls.c
	Added the data filter pipeline, a generalization of the
	compression stuff which allows things like checksums,
	encryption, compression, performance monitoring, etc.  See
	./doc/html/Filters.html for details -- it replaces the
	Compression.html doc.

./src/H5T.c
	Cleaned up debugging output.

./config/linux
	Added checks for egcs and pgcc and changed optimization flags
	for the compilers.

./src/H5G.c
./tools/h5dump.c
	Fixed compiler warnings in these files and others.

./configure.in
./src/H5private.h
./test/mtime.c
	Added a check for difftime() and defined HDdifftime() to do
	something else on systems that don't have difftime().
