qa/checksum: Add python code to verify a sha256,md5sum
Store md5 and sha256 sums in a ini file and verify it with a local file. This code has been tested (manually) on OSX and should be integrated into either OE or BitBake

+# Helper utilitiy to verify checksums of SRC_URI's
+#
+# To ease parsing I will use INI files to contain the
+# checksums, at least they will force some kind of structure. This allows
+# to easily add and replace new sums
+#
+#
+# Example:
+# [PN-PV-filename]
+# md5=THESUM
+# sha256=OTHERSUM
+#
+# [PN-filename]
+# md5=THESUM
+# sha256=OTHERSUM
