lib/bb/siggen: show a diff when dumping changes to multi-line values
When dumping changes to signatures e.g. output of bitbake -s printdiff, if for example a function has changed, it's much more readable to see a unified diff of the changes rather than just printing the old function followed by the new function, so use difflib to do that. Note: I elected to keep to one item in the returned list per change, rather than one line per line of output, so that the caller can still look at changes individually if needed. Thus I've added some handling to bitbake-diffsigs to split the change into lines so that each line is displayed indented.
