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).

-/* I/O port access on the ARM is something of a fiction.  What we do is to
-   map an appropriate area of /dev/mem into user space so that a program
-   can blast away at the hardware in such a way as to generate I/O cycles
-   on the bus.  To insulate user code from dependencies on particular
-   hardware we don't allow calls to inb() and friends to be inlined, but
-   force them to come through code in here every time.  Performance-critical
-   registers tend to be memory mapped these days so this should be no big
-   problem.  */
-
-/* Once upon a time this file used mprotect to enable and disable
-   access to particular areas of I/O space.  Unfortunately the
-   mprotect syscall also has the side effect of enabling caching for
-   the area affected (this is a kernel limitation).  So we now just
-   enable all the ports all of the time.  */
