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.

+Subject: [PATCH] hooks:  disable malloc override inside of Gentoo sandbox
+
+As described in the comments in the source, Gentoo's own version of
+fakeroot, sandbox, also runs into hangs when malloc is overridden.
+Sandbox environments can easily be detected by looking for SANDBOX_PID
+in the environment.  When detected, employ the same fix used for
+fakeroot.
+
+See https://bugs.gentoo.org/show_bug.cgi?id=462602
