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] support parsing of dynamic ELFs w/out section headers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+At runtime, ELFs do not use the section headers at all. Instead, only
+the program segments and dynamic tags get used. This means you can
+strip the section table completely from an ELF and have it still work.
+
+In practice, people rarely do this, but it's not unheard of. Make the
+Dynamic tags work even in these cases by loading the strings table the
+same way the runtime loader does:
+ * parse the symtab address from DT_STRTAB
+ * locate the file offset via the program segments
+
+In order to avoid circular deps (parsing a dyntag requires walking parsed
+dyntags), add a set of internal funcs for returning the raw values.
+
+You can see this in action:
+$ eu-strip -g --strip-sections a.out
+$ readelf -S a.out
+<nothing>
+$ lddtree.py ./a.out
+a.out (interpreter => /lib64/ld-linux-x86-64.so.2)
+    libïäöëß.so => None
+    libc.so.6 => /lib64/libc.so.6
