image.bbclass: Add a method for creating a companion debug filesystem
The companion debug filesystem contains only the package database and the complementary *-dbg packages for the main filesystem component. This is useful in a production environment to produce a companion filesystem capable of remote system debugging, without requiring corresponding debug symbols or source code on the device. Signed-off-by: Mark Hatle <mark.hatle@windriver.com> Signed-off-by: Robert Yang <liezhi.yang@windriver.com> If dbg pkgs have already been installed to the rootfs image, the installation to companion debug filesystem will fail, because both of image creation make use of the same pm database. In this situation, try to copy installed dbg files from rootfs image to companion debug filesystem.
