[svn-r335] Changes since 19980330

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

./MANIFEST
./src/Makefile.in
./test/Makefile.in
        Added new files.

./config/linux
./src/H5HL.c
./src/H5HLprivate.h
./src/H5MF.c
./src/H5MFprivate.h
        Added `-DH5HL_DEBUG -DH5MF_DEBUG' to the debug list.

./html/H5.format.html
        Updated shared object message information.

./src/H5D.c
        Datasets can now share data types.

./src/H5F.c
        Updated a comment that referred to H5ACC_WRITE.

./src/H5HG.c
./src/H5HGprivate.h
        Moved a few things around.  Made debugging better so you can
        now give a collection address to ./src/debug and it shows some
        useful stuff.

./src/H5O.c
./src/H5Ocont.c
./src/H5Odtype.c
./src/H5Oefl.c
./src/H5Olayout.c
./src/H5Oname.c
./src/H5Onull.c
./src/H5Oprivate.h
./src/H5Osdspace.c
./src/H5Oshared.c       [NEW]
./src/H5Ostab.c
        Supports shared messages.

./src/H5T.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
        The H5Tshare() function allows the user to give the library
        hints about how a data type will be used.

./test/shtype.c
        Tests the H5Tshare() function.

./test/gheap.c
        Tests the global heap.

./configure.in
./config/BlankForm      [NEW]
./config/alpha-dec
./config/freebsd2.2.1
./config/hpux10.20
./config/irix6.2
./config/irix64
./config/linux
./config/powerpc-ibm-aix4.2.1.0
./config/rs6000-ibm-aix4.1.4.0
./config/solaris2.5
        Cleaned up lots of configuration stuff and made the site
        configuration files lots easier and more uniform.  To make a
        new file grab the BlankForm and modify it.

        By default, debugging is turned on for most packages.  Within
        a package one can use `#ifdef H5AC_DEBUG' to wrap debugging
        code.  Other options are:

           --enable-debug
           --enable-debug=yes
               The default, most but not all packages.

           --disable-debug
           --enable-debug=no
           --enable-debug=none
               The symbol NDEBUG is defined and none of the package
               debug symbols.

           --enable-debug=all
               Debugging is turned on for all packages.  This might
               produce lots of output.

           --enable-debug=g,d
               Debugging is turned on for H5G and H5D.

        A compile mode is also now supported

           --enable-production
           --enable-production=yes
               The library is compiled with optimizations turned on.
               The compiler flags are augmented by adding PROD_CFLAGS
               and PROD_CPPFLAGS which are defined in the site config
               file.

           --disable-production
           --enable-production=no
               The default.  The library is compiled for development
               by including DEBUG_CFLAGS and DEBUG_CPPFLAGS defined in
               the site config file.  This is usually just `-g'.

           --enable-production=profile
           --enable-production=pg
               Builds a library for profiling by including the flags
               from PROFILE_CFLAGS and PROFILE_CPPFLAGS defined in the
               site config file.  This is usullay just `-pg' but it
               could include optimization flags as well depending on
               the type of profile one wants.

        In summary, configure by saying `./configure' and you'll get a
        development version of the library.  Configure by saying
        `./configure --enable-production --disable-debug' and you'll
        get a production version with no debugging code.
