[svn-r19506] Bring changes from revisions 19408, 19421, and 19442 from branches/hdf5_1_8 to trunk. These revisions reorganize the compile scripts using h5cc.in, h5fc.in, and h5c++.in, add checks for installed examples to the scripts that run them after installation, and add DESTDIR for install as needed for RPMs.

Tested on amani, heiwa and jam by h5committest and with CYGWIN.

+# Note that in svn revision 19400 the '/' after DESTDIR in H5* variables below  
+# has been removed. According to the official description of DESTDIR by Gnu at 
+# http://www.gnu.org/prep/standards/html_node/DESTDIR.html, DESTDIR is 
+# prepended to the normal and complete install path that it precedes for the 
+# purpose of installing in a temporary directory which is useful for building 
+# rpms and other packages.  The '/' after ${DESTDIR} will be followed by another 
+# '/' at the beginning of the normal install path.  When DESTDIR is empty the  
+# path then begins with '//', which is incorrect and causes problems at least for 
+# Cygwin.
