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.

+# @ECLASS-VARIABLE: EGO_PN
+# @REQUIRED
+# @DESCRIPTION:
+# This is the import path for the go package(s). Please emerge dev-lang/go
+# and read "go help importpath" for syntax.
+#
+# Example:
+# @CODE
+# EGO_PN="github.com/user/package"
+# EGO_PN="github.com/user1/package1 github.com/user2/package2"
+# @CODE
+
+# @ECLASS-VARIABLE: EGO_SRC
+# @DESCRIPTION:
+# This is the Go upstream repository which will be copied to
+# ${WORKDIR}/${P}.
+# If it isn't set, it defaults to the first word of ${EGO_PN}.
+# This should be set if you are retrieving a repository that includes
+# multiple packages, e.g. golang.org/x/tools.
+#
+# Example:
+# @CODE
+# EGO_PN="github.com/user/repository/..."
+# EGO_SRC="github.com/user/repository"
+# @CODE
+
+# @ECLASS-VARIABLE: EGO_STORE_DIR

+# Storage directory for Go sources.
+#
+# This is intended to be set by the user in make.conf. Ebuilds must not set
+# it.
+#
+# EGO_STORE_DIR=${DISTDIR}/go-src

+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# If non-empty, this variable prevents any online operations.
+
+# @ECLASS-VARIABLE: EVCS_UMASK
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# Set this variable to a custom umask. This is intended to be set by
+# users. By setting this to something like 002, it can make life easier
+# for people who do development as non-root (but are in the portage
+# group) and use FEATURES=userpriv.
