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).

-  ALGORITHM DESCRIPTION:
-
-  1) Range reduction to [-Pi/2; +Pi/2] interval
-    a) We remove sign using AND operation
-    b) Add Pi/2 value to argument X for Cos to Sin transformation
-    c) Getting octant Y by 1/Pi multiplication
-    d) Add "Right Shifter" value
-    e) Treat obtained value as integer for destination sign setting.
-       Shift first bit of this value to the last (sign) position
-    f) Subtract "Right Shifter"  value
-    g) Subtract 0.5 from result for octant correction
-    h) Subtract Y*PI from X argument, where PI divided to 4 parts:
-         X = X - Y*PI1 - Y*PI2 - Y*PI3 - Y*PI4;
-  2) Polynomial (minimax for sin within [-Pi/2; +Pi/2] interval)
-    a) Calculate X^2 = X * X
-    b) Calculate polynomial:
-         R = X + X * X^2 * (A3 + x^2 * (A5 + .....
-  3) Destination sign setting
-    a) Set shifted destination sign using XOR operation:
-         R = XOR( R, S );
