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).

-# #errlist-compat NNN
-# where NNN is the number of elements in the sys_errlist for that version set.
-# We need the awk variable `maxerr' defined to the current size of sys_errlist.
-#
-# If there is no magic comment matching the current size, we barf.
-# Otherwise we generate code (errlist-compat.c) to define all the
-# necessary compatibility symbols for older, smaller versions of sys_errlist.

-# These two rules catch the Versions file contents.
