populate_sdk_ext: add extensible SDK
This bbclass will create an SDK with a copy of bitbake and the metadata and sstate for the target specified for the task. The idea is to let "system" developers both work on applications and then test adding them to an image without having to switch between workspaces or having to download separate items. Rather than running bitbake directly however, the primary way of running builds within the extensible SDK is to use the "devtool" command. The rest of the build system is fixed via locked shared state signatures, and thus only the recipes you have added get built.
