bitbake: siggen: Add new unitaskhashes data variable which is cached
We need to preserve unihash task hashes between runs. Use the new SimpleCache class to create such a class within the signature generator which is loaded at init time and saved when builds complete. The default is unpopulated but metadata sig handlers can populate this cache. (Bitbake rev: 1f326f2c29c2664a5daaeeb0c1fd332630efbdba) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
