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 for
+# software written in the Go programming language
+# @DESCRIPTION:
+# This eclass provides a convenience src_unpack() which unpacks the
+# first tarball mentioned in SRC_URI to its appropriate location in
+# ${WORKDIR}/${P}, treating ${WORKDIR}/${P} as a go workspace.
+#
+# The location where the tarball is extracted is defined as
+# ${WORKDIR}/${P}/src/${EGO_PN}.
+#
+# The typical use case is VCS snapshots coming from github, bitbucket
+# and similar services.
+#
+# Please note that this eclass currently handles only tarballs
+# (.tar.gz), but support for more formats may be added in the future.
+#
+# @EXAMPLE:
+#
+# @CODE
+# EGO_PN=github.com/user/package
+# inherit golang-vcs-snapshot
+#
+# SRC_URI="http://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz"
+# @CODE
+#
+# The above example will extract the tarball to
+# ${WORKDIR}/${P}/src/github.com/user/package
