[svn-r19507] Fix for bug 1707 - I changed the design from the previous fix as Quincey suggested. I added a

flag IS_DEDAULT in the H5E_auto_t structure.  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 jam, heiwa, and amani.
