[svn-r19457] Bug fix for 1707 - H5Eset_auto causes a seg fault when an application uses -DH5_USE_16_API with the 1.8 library to compile. The cause is from the mismatch of H5Eprint1 and H5Eprint2 set

through H5Eset_auto.  I changed the union in the structure H5E_auto_t.  Another change is to 
make H5Eget_auto fail if H5Eset_auto is called to set the printing function.  I'll write a 
document for it.

Tested on heiwa, jam, and amani.

The property change in configure.in, config, and Makefile.am came from the merge of the 1.8 
library change.
