[svn-r1379] 

Two new examples h5_mount.c and h5_reference.c were added.
h5_select.c was modified to use fill values, and h5_group.c was modified
to show how H5Giterate can be used to get information about the objects in
a group.

Necessary changes were done to the Makefile.in.

Tested on Solaris 2.6 (baldric)
