[svn-r19583] 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 structure H5E_auto_t.  I added a IS_DEDAULT flag in 
it.  Both H5Eprint1/2 are the default now.  If the user sets his/her own printing function.
Then a call to H5Eget_auto1/2 will have to match H5Eset_auto1/2.  

Tested on heiwa, jam, and amani.

The property change in configure.in, config, tools/misc, tools/lib, c++/test, fortran, and 
Makefile.am came from the merge of the trunk library change.
