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).

-# How to link against libgcc.  Some libgcc functions, such as those
-# for "long long" arithmetic or software floating point, can always be
-# built without use of C library headers and do not have any global
-# state so can safely be linked statically into any executable or
-# shared library requiring them; these functions are in libgcc.a.
-# Other functions, relating to exception handling, may require C
-# library headers to build and it may not be safe to have more than
-# one copy of them in a process; these functions are only in
-# libgcc_s.so and libgcc_eh.a.
-#
-# To avoid circular dependencies when bootstrapping, it is desirable
-# to avoid use of libgcc_s and libgcc_eh in building glibc.  Where any
-# glibc functionality (in particular, thread cancellation) requires
-# exception handling, this is implemented through dlopen of libgcc_s
-# to avoid unnecessary dependencies on libgcc_s by programs not using
-# that functionality; executables built with glibc do not use
-# exception handling other than through thread cancellation.
-#
-# Undefined references to functions from libgcc_eh or libgcc_s may
-# arise for code built with -fexceptions.  In the case of statically
-# linked programs installed by glibc, unwinding will never actually
-# occur at runtime and the use of elf/static-stubs.c to resolve these
-# references is safe.  In the case of statically linked test programs
-# and test programs built with -fexceptions, unwinding may occur in
-# some cases and it is preferable to link with libgcc_eh or libgcc_s
-# so that the testing is as similar as possible to how programs will
-# be built with the installed glibc.
