Prepare for radical source tree reorganization. zack/build-layout-experiment

All top-level files and directories are moved into a temporary storage
directory, REORG.TODO, except for files that will certainly still
exist in their current form at top level when we're done (COPYING,
COPYING.LIB, LICENSES, NEWS, README), all old ChangeLog files (which
are moved to the new directory OldChangeLogs, instead), and the
generated file INSTALL (which is just deleted; in the new order, there
will be no generated files checked into version control).

+ * svc_auth_unix.c
+ * Handles UNIX flavor authentication parameters on the service side of rpc.
+ * There are two svc auth implementations here: AUTH_UNIX and AUTH_SHORT.
+ * _svcauth_unix does full blown unix style uid,gid+gids auth,
+ * _svcauth_short uses a shorthand auth to index into a cache of longhand auths.
+ * Note: the shorthand has been gutted for efficiency.
