Bitbake minimum version increment likely soon

This is just a heads up that I'm likely to increase the minimum version of bitbake OE-Core depends on soon. This has been brewing for a while since there is some new data store syntax I'd like to start using (e.g. d.appendVar).

The reason to do it now is to deal with various siggen issues that are becoming apparent. I proposed the changes several months ago in pseudo code but have now written the patches and would like to take advantage of them. These get rid of the horrible regexp and use a python function to filter dependencies instead.

There have also been error handling improvements in bitbake recently and I'd like to ensure people benefit from those too.

Cheers,

Richard
