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).

-/* __ieee754_asin(x)
- * Method :
- *	Since  asin(x) = x + x^3/6 + x^5*3/40 + x^7*15/336 + ...
- *	we approximate asin(x) on [0,0.5] by
- *		asin(x) = x + x*x^2*R(x^2)
- *      Between .5 and .625 the approximation is
- *              asin(0.5625 + x) = asin(0.5625) + x rS(x) / sS(x)
- *	For x in [0.625,1]
- *		asin(x) = pi/2-2*asin(sqrt((1-x)/2))
- *	Let y = (1-x), z = y/2, s := sqrt(z), and pio2_hi+pio2_lo=pi/2;
- *	then for x>0.98
- *		asin(x) = pi/2 - 2*(s+s*z*R(z))
- *			= pio2_hi - (2*(s+s*z*R(z)) - pio2_lo)
- *	For x<=0.98, let pio4_hi = pio2_hi/2, then
- *		f = hi part of s;
- *		c = sqrt(z) - f = (z-f*f)/(s+f) 	...f+c=sqrt(z)
- *	and
- *		asin(x) = pi/2 - 2*(s+s*z*R(z))
- *			= pio4_hi+(pio4-2s)-(2s*z*R(z)-pio2_lo)
- *			= pio4_hi+(pio4-2f)-(2s*z*R(z)-(pio2_lo+2c))
- *
- * Special cases:
- *	if x is NaN, return x itself;
- *	if |x|>1, return NaN with invalid signal.
