CN: Add a library for thumbnail generation based on dtdriver

Thanks Greg.
I replaced DEFINE_GUID to DEFINE_GUID_ENUM, and checked in to HEAD and Atlas310.

Now you can build the library (libhxthumb.so) with following configuration:
[0] Set BIF branch (hxclient_3_1_0_atlas)
[1] Set Target(s) (dtdr_thumb-generator)
[2] Set Profile (/home/halley/helix_cvs/build/umakepf/helix-client-moblin)
[3] run: build
It will search Helix engine in following order: $HELIX_THUMB_LIBS > $HELIX_LIBS/thumbnail > "/opt/helix/mediaplatform/thumbnail"

A sample test in that folder says how to use this library.

hxiids.h should have "DEFINE_GUID_ENUM"s in it, not DEFINE_GUIDs
