DRTVWR-418: Fix indra/llkdu wrapper for changes in KDU 7.8 API.

KDU 7.8 introduces a number of changes to its API, most notably by moving
public symbols into a variety of kdu_something namespaces. While this is
laudable in a general sense, it does require quite a bit of diagnostic
building and patching to update legacy code.

Since llimagej2ckdu_test.cpp lamentably stubs out pretty much the entire KDU
API, we must also fix those stubs for signature changes even to functions we
don't otherwise reference.

NOTE: This commit still leaves four symbols undefined. Below I have taken the
liberty of juxtaposing the error line with the output from dumpbin /exports
build-vc120/packages/lib/release/kdu.lib. I see no differences.
