possible future entitycheck change

["Wichmann, Mats D" <mats.d.wichmann@intel.com>]

Occurred to me while I *wasn't* thinking
about it, that there's some benefit to
combining the package_update functionality
into the entity checker.  The entity
checker already breaks apart the entities/package
file into a package identifier and the
name of the tarball or patch file.
So all that's really needed is to provide
a package_locations file indexed by
package identifier that the checker can
use to update the source tree.


Maybe I'll code that up, and maybe not...
