[svn-r471] Changes since 19980708

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

./MANIFEST
	Alphabetized.  `d' comes before `e' :-)

./bin/release
	Added the `-batch' option which causes the script to not ask
	questions and to automatically update the minor version
	number and set the patch level back to `a'.  This is intended
	to be used for the daily snapshots:

	   #! /bin/sh
	   set -e
	   cd ~/hdf5
	   make distclean
	   make test
	   bin/release -batch tar compress gzip bzip2
	   mv ./releases/* /repository

./src/H5Z.c
	Removed warnings about unused variables when the zlib.h header
	file is present but libz.a isn't.

./INSTALL
./configure.in
./doc/html/tracing.html
	Made API tracing the default (you still need to define the
	HDF5_TRACE environment variable to get results) and change the
	name from `--disable-tracing' to `--disable-trace' to make it
	consistent with the other switches.

	Changed `site config file' to `host config file' to match the
	documentation.

./doc/html/H5.user.html
	Added a reference to the `tracing.html' file.
