Takes the specified layers (or all layers in the current layer

containing the contents of all layers, with any overlayed recipes removed
and bbappends appended to the corresponding recipes. Note that some manual
cleanup may still be necessary afterwards, in particular:

* where non-recipe files (such as patches) are overwritten (the flatten
  command will show a warning for these)
* where anything beyond the normal layer setup has been added to
  layer.conf (only the lowest priority number layer's layer.conf is used)
* overridden/appended items from bbappends will need to be tidied up
* when the flattened layers do not have the same directory structure (the
  flatten command should show a warning when this will cause a problem)

Warning: if you flatten several layers where another layer is intended to
be used "inbetween" them (in layer priority order) such that recipes /
bbappends in the layers interact, and then attempt to use the new output
layer together with that other layer, you may no longer get the same
build results (as the layer priority order has effectively changed).
