dfxml_configure.m4 should set AC_LANG to C++ before checking for exiv2 headers

I'm compiling bulk_extractor 1.4.0 beta 2
During configure:
...
configure: Including dfxml_configure.m4 from dfxml

checking afflib/afflib.h presence... yes
checking for afflib/afflib.h... yes
checking err.h usability... yes

But exiv2 is installed and exiv2/image.hpp is here.
Maybe there should be AC_LANG_PUSH(C++) / AC_LANG_POP() aroung the check for exiv2/image.hpp header.
Good idea. Although perhaps we should just take out exiv2, as we are abandoning it. What's your thought?
If exif works better than exiv2 I see not problem abandoning it.
where is no exif that we use. bulk_extractor has its own exif implementation, but it's not suitable for anything other than bulk_extractor. exiv2 does more, but it is buggier.
