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).

-/* NOTE: Because of the special way this file is used by <math.h>, this
-   file must NOT be protected from multiple inclusion as header files
-   usually are.
-
-   This file provides prototype declarations for the math functions.
-   Most functions are declared using the macro:
-
-   __MATHCALL (NAME,[_r], (ARGS...));
-
-   This means there is a function `NAME' returning `double' and a function
-   `NAMEf' returning `float'.  Each place `_Mdouble_' appears in the
-   prototype, that is actually `double' in the prototype for `NAME' and
-   `float' in the prototype for `NAMEf'.  Reentrant variant functions are
-   called `NAME_r' and `NAMEf_r'.
-
-   Functions returning other types like `int' are declared using the macro:
-
-   __MATHDECL (TYPE, NAME,[_r], (ARGS...));
-
-   This is just like __MATHCALL but for a function returning `TYPE'
-   instead of `_Mdouble_'.  In all of these cases, there is still
-   both a `NAME' and a `NAMEf' that takes `float' arguments.
-
-   Note that there must be no whitespace before the argument passed for
-   NAME, to make token pasting work with -traditional.  */
