GIT checkin of 0059-Add-libdpx-status-to-configure-summary.patch AND fileogg.C rest of 50% patch.

I'll wait a bit until second half of ogg ifdefing lands, so git hopefully rebase with less rejects...

I had already redone the libvpx.patch when it failed so I could compile, but later put in Andrew's 0070-Fix-libdpx-patch.patch anyway. And of course, added in 0071-Add-without-libdpx-to-configure.patch and did a rebuild.

i think I missed piece adding LIBDPX among group of deps so libdpx's status displayed at the end of configure

BUT, I have not been able to actually get a DPX list file to load (hoping Andrea can).

how you tried to construct said list? manually, by script, as output from another program?

Not sure what I did wrong and how I got it to crash oritinally , but now it is working either with "try FFmpeg first or last". To construct a test, I rendered a single frame using ffmpeg/dpx and did this for 4 different frames. Then I created the list manually in a directory with the filename of dpx.dpxs. Finally I loaded dpx.dpxs and all 4 frames appeared.
