Totally rework the math library, this time based on the MacOs X

math library (which is itself based on the math lib from FreeBSD).

-/*							ellpk.c
- *
- *	Complete elliptic integral of the first kind
- *
- *
- *
- * SYNOPSIS:
- *
- * double m1, y, ellpk();
- *
- * y = ellpk( m1 );
- *
- *
- *
- * DESCRIPTION:
- *
- * Approximates the integral
- *
- *
- *
- *            pi/2
- *             -
- *            | |
- *            |           dt
- * K(m)  =    |    ------------------
- *            |                   2
- *          | |    sqrt( 1 - m sin t )
- *           -
- *            0
- *
- * where m = 1 - m1, using the approximation
- *
- *     P(x)  -  log x Q(x).
- *
- * The argument m1 is used rather than m so that the logarithmic
- * singularity at m = 1 will be shifted to the origin; this
- * preserves maximum accuracy.
- *
- * K(0) = pi/2.
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    DEC        0,1        16000       3.5e-17     1.1e-17
- *    IEEE       0,1        30000       2.5e-16     6.8e-17
- *
- * ERROR MESSAGES:
- *
- *   message         condition      value returned
- * ellpk domain       x<0, x>1           0.0
