license: simple verification of LICENSE_<pkg> values
LICENSE should be a superset of all LICENSE_<pkg> values. That is, LICENSE should contain all licenses and LICENSE_<pkg> can be used to "filter" this on a per-package basis. LICENSE_<pkg> shouldn't contain anything that isn't specified in LICENSE. This patch implements simple checking of LICENSE_<pkg> values. It does do not do advanced parsing/matching of license expressions, but, checks that all licenses mentioned in LICENSE_<pkg> are also specified in LICENSE. A warning is printed if problems are found.
