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).

-/* This file is included by the tst-affinity*.c files to test the two
-   variants of the functions, under different conditions.  The
-   following functions have to be definied:
-
-   static int getaffinity (size_t, cpu_set_t *);
-   static int setaffinity (size_t, const cpu_set_t *);
-   static bool early_test (struct conf *);
-
-   The first two functions shall affect the affinity mask for the
-   current thread and return 0 for success, -1 for error (with an
-   error code in errno).
-
-   early_test is invoked before the tests in this file affect the
-   affinity masks.  If it returns true, testing continues, otherwise
-   no more tests run and the overall test exits with status 1.
