checklayer: avoid recursive loop in add_layer_dependencies
When Layer A and Layer B depend on each other, then we will end up in a recursive loop in function recurse_dependencies(). To avoid such situation before making the recursive function call we check whether or not we have already processed this layer. e.g. without this patch, running this script on layers with dependency loops, we are seeing: $ yocto-check-layer -d /srv/work/oe/meta-openembedded/ INFO: Detected layers: INFO: meta-python: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-python INFO: meta-filesystems: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-filesystems INFO: meta-gnome: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-gnome INFO: meta-xfce: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-xfce INFO: meta-networking: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-networking INFO: meta-initramfs: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-initramfs INFO: meta-oe: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-oe INFO: meta-multimedia: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-multimedia INFO: meta-perl: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-perl INFO: meta-webserver: LayerType.SOFTWARE, /srv/work/oe/meta-openembedded/meta-webserver INFO: INFO: Setting up for meta-python(LayerType.SOFTWARE), /srv/work/oe/meta-openembedded/meta-python DEBUG: Processing dependencies core openembedded-layer for layer meta-python.
