[svn-r9185] Purpose:

New Feature.

Description:
Before this update, we use per_hdf_library convention to set environment variables for gzip and szip compression libraries, for example, HDF5_EXT_LIBS = zlib.lib szlib.lib.

As some of HDF5 dump and repack tests should be skipped when gzip/szip are disabled.  But we found it was very complicated to check whether gzip/szip were disabled in Windows with the per_hdf_library convention.  Using per_external_library naming convention makes the checking much easier.  So we decide to convert to per_external_library naming convention.

A new environment variable H5_SZIP_CAN_ENCODE is added to check whether szip encoding is enabled.

dumptest.bat and repacktest.bat batch files are also updated so these tests which use gzip/szip filters will be skipped when gzip/szip are disabled and will be tested when gzip/szip are enabled.

Solution:
Now we should set the following environment variables:
HDF5_EXT_ZLIB = zlib.lib
HDF5_EXT_SZIP = szlib.lib
HDF5_EXT_ZLIB_DLL = c:\zlib114\dll\zlib.lib
HDF5_EXT_SZIP_DLL = szlibdll.lib
when we want to enable gzip/szip.

Set H5_SZIP_CAN_ENCODE as 1 when szip encoding is enabled and as 0 when szip encoding is disabled.

Platforms tested:
Visual C++ 6.0 on Windows 2000/XP.
(Will test with .NET after this check-in).
