recipetool: add 'newappend' sub-command
This sub-command creates a bbappend for the specified target and prints the path to the bbappend. The -w argument, as with some of the other recipetool commands, will make a version-independent bbappend. Example usage: recipetool newappend meta-mylayer virtual/kernel [YOCTO #7964] (From OE-Core rev: ac053163c7823e482ca1af2962342e64a54bfb52) Signed-off-by: Christopher Larson <kergoth@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
