lib/oe: Add sstatesig, OE specific signature generator classes
This patch adds SignatureGenerator classes specific to OE. For now, these emulate the previous behaviour with the exception that dependencies on quilt-native are now ignored for checksum purposes. The intent is to allow easier experimentation and customisation of this code in future as a result of these changes. Note that these changes require pending bitbake patches. (From OE-Core rev: cb73cf4299a192e6065d567fae700987c3f937aa) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
