devtool: export: new plugin to export the devtool workspace
By default, exports the whole workspace (all recipes) including the source code. User can also limit what is exported with --included/--excluded flags. As a result of this operation, a tar archive containing only workspace metadata and its corresponding source code is created, which can be properly imported with 'devtool import'. https://bugzilla.yoctoproject.org/show_bug.cgi?id=10510 [YOCTO #10510] (From OE-Core rev: f9bc3b5101b554a72298266519dbdd1497f262a6) Signed-off-by: Leonardo Sandoval <leonardo.sandoval.gonzalez@linux.intel.com> Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
