[LEDE-DEV] [PATCH v2 0/2] enhance UID/GID assignment

In a previous thread "convention on uid/gid for packages" we explored the
cons/pros of static and dynamic assignment uid/gid.  I tried to sum up the
discussion in a separate document [2]

Conclusions at the moment are

 - We still need to retain both static and dynamic assignment
 - We do not want to maintain a central global list for static assignment
   scattered around in all those feeds
 - We need to address the potential issue of id collisions between the two
   allocation schemes

This series contains mainly the following changes

 - Ensure that build will fail if there are collisions in the packages list
 - Start dynamic allocation from 65536 instead of 100

v2 <- v1

	- Dropped the change trying to separating multiple tuples in Require-User
	  field with commas
