recipetool: allow plugins to set LICENSE and LIC_FILES_CHKSUM
We were being a bit prescriptive in setting LICENSE and LIC_FILES_CHKSUM. We can't always trust what's in the metadata accompanying some source which plugins will almost always be pulling from, however we do want to allow plugins to set the LICENSE and LIC_FILES_CHKSUM values. Merge what we find in our license file scan with what the plugin sends back. Additionally, plugins can now add a "license" item to the handled list in order to inhibit the normal LICENSE / LIC_FILES_CHKSUM handling if they have already taken care of it completely. Thanks to Mark Horn <mark.d.horn@intel.com> for prompting, testing and fixing this patch. (From OE-Core rev: 1df60b09f7a60427795ec828c9c7180e4e52f98c) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
