hdf5_ep

[svn-r1421] Divide the whole script into two parts, test and release, so that the
two tasks can be done selectively.  This is mainly to allow doing the
test without running the release part automatically.  After this is
tested out more to work fine, the "cvs checkout" part will be pulled
out also, so that it is possible to stage the cvs checkout during the
daytime when user is around to provide the AFS token.  The test part
can be done at night by cron, provided the latest source has been
"staged".  Following a successful test, the user can do the release
part by hand later, again with AFS tokens.
Also added options for using different locations of HDF4 library
and the ARCHIVE areas.  Making it useful for different machines
setup.
