licensing: Add licensing metadata to many packages Two new variables are introduces to many packages, namely PKG_LICENSE and PKG_LICENSE_FILES - there may be more than one license applied to packages, and these are listed in the PKG_LICENSE variable and separated by spaces. All relevant license files are also added to the PKG_LICENSE_FILES variable, also space separated.

The licensing metadata is put into the bin/<platform>/packages/Packages file
for later parsing. A script for that is on it's way!
