proj/gentoo: Initial commit

This commit represents a new era for Gentoo:
Storing the gentoo-x86 tree in Git, as converted from CVS.

This commit is the start of the NEW history.
Any historical data is intended to be grafted onto this point.

Creation process:
1. Take final CVS checkout snapshot
2. Remove ALL ChangeLog* files
3. Transform all Manifests to thin
4. Remove empty Manifests
5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$
5.1. Do not touch files with -kb/-ko keyword flags.

+# ebuild, set the ECLASS VARIABLES as specified below in your ebuild before
+# inheriting. Then either leave the default src_unpack or extend over
+# cvs_src_unpack. If you find that you need to call the cvs_* functions
+# directly, I'd be interested to hear about it.
