Add eclass which overrides existing portage mechanisms for UID/GID management.
In accordance with http://www.gentoo.org/proj/en/glep/glep-0027.html, this
patch adds a mechanism for managing UIDs and GIDs centrally and consistently
in a build environment. Users and groups are managed by a tree of files
containing key:value pairs as discussed in the GLEP. Examples and more
can be found in the profiles/base/accounts/README.
