Subject: Add sha256 ckecksums to okpg

Thanks to Camille Moncelier <moncelier@devlife.org>
http://groups.google.com/group/opkg-devel/browse_thread/thread/78a2eb328da0ef73?utoken=pV1Kli0AAADKDldt5ZXsDDLs9sWCpWZI0mClVcTs45ANzZ7C9NH-1YGBxa5Bow63PTuzFmQCb1c

Here is a patch which adds sha256 checksum checking to Opkg.
More Opkg patches will follow shortly (x509 and smime signature support,
libcurl client/server authentication)

I hope these patch will be useful and finds their ways into okpg
