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).

+# Some files which need to go both into libc and libm have external
+# dependencies which need to be resolved differently for libc
+# vs. libm.  For example, inside libc, __libm_error_support needs to
+# resolve to HIDDEN_JUMPTARGET(__libm_error_support) whereas within
+# libm it always resolves to __libm_error_support.  Such files need to
+# be compiled twice.  Fortunately, math/Makefile already has logic to
+# support this: if a file starts with "s_", make will automatically
+# generate a matching file whose name starts with "m_" which simply
+# includes the corresponding "s_" file.
