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.

+# @BLURB: support eclass for unpacking VCS snapshot tarballs
+# @DESCRIPTION:
+# This eclass provides a convenience src_unpack() which does unpack all
+# the tarballs in SRC_URI to locations matching their (local) names,
+# discarding the original parent directory.
+#
+# The typical use case are VCS snapshots, coming from github, bitbucket
+# and similar services. They have hash appended to the directory name
+# which makes extracting them a painful experience. But if you just use
+# a SRC_URI arrow to rename it (which you're likely have to do anyway),
+# vcs-snapshot will just extract it into a matching directory.
+#
+# Please note that this eclass handles only tarballs (.tar, .tar.gz,
+# .tar.bz2 & .tar.xz). For any other file format (or suffix) it will
+# fall back to regular unpack. Support for additional formats may be
+# added at some point so please keep your SRC_URIs clean.
+#
+# @EXAMPLE:
+#
+# @CODE
+# EAPI=4
+# AUTOTOOLS_AUTORECONF=1
+# inherit autotools-utils vcs-snapshot
+#
+# SRC_URI="http://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz"
+# @CODE
+#
+# and however the tarball was originally named, all files will appear
+# in ${WORKDIR}/${P}.
