    Update GSL to version 1.15

    New in gsl-1.15:

    ** Added Tuomo Keskitalo's new ode branch ode-initval2 with a
       gsl_odeiv2 prefix. This provides proper support for implicit
       solvers.  It is intended to be the new default for differential
       equations.  The existing gsl_odeiv routines will be retained for
       binary compatibility but their interface will be deprecated.

    ** Added new gsl_integrate_cquad routines for robust integration of
       difficult functions using the doubly-adaptive CQUAD algorithm
       (Pedro Gonnet).

    ** Added error checking to CBLAS functions (Jose Luis Garcia Pallero)

    ** Added a new function gsl_integration_glfixed_point to return
       ordered Gauss-Legendre points and weights contained within a
       gsl_integration_glfixed_table [bug #32237].

    ** Added a new function gsl_interp_type_min_size to return the size of
       an interpolation type.

    ** Added a function gsl_pow_uint(x,n) to compute x^n for unsigned
       exponents (needed when n exceeds the range of signed integers).

    ** Added new routine gsl_linalg_complex_cholesky_invert to handle the
       matrix inversion for complex Cholesky decompositions (Huan Wu).

    ** Added the functions gsl_vector_equal(x,y) and gsl_matrix_equal(x,y)
       for testing equality of two vectors or matrices.

    ** Added function gsl_eigen_nonsymmv_params to control the balancing
       transformation for eigenvector calculations. Balancing is now
       turned off by default for gsl_eigen_nonsymmv.

    ** It is now possible to choose an alternative cblas library via
       pkg-config using the GSL_CBLAS_LIB environment variable or
       the pkg-config --define-variable option.

    ** The jacobi method gsl_eigen_jacobi now uses the norm of the
       off-diagonal elements for its convergence criterion, as in
       algorithm 8.4.3 of Golub and van Loan.

    ** The newton multiroot solvers now return an error when a singular
       jacobian is detected.

    ** The interpolation functions now return NaN and when x is out of range,
       instead of extrapolating.

    ** The gsl_multimin_fdfsolver multidimensional minimisers now return
       GSL_ENOPROG immediately if the generated trial point does not
       differ from the initial point (to machine precision), avoiding
       unnecessary further iterations.

    ** Extended the range of gsl_sf_bessel_lnKnu_e by rescaling
       intermediate results to avoid internal overflows [bug #31528].

    ** Improved the result of gsl_sf_atanint_e for large arguments by
       adding the first order 1/x correction term. [bug #29562]

    ** Fixed the gsl_rng_ranlxs generators to enforce a maximum seed value
       of 2^31-1.  Larger seed values caused out of range values to be
       returned.

    ** Fixed gsl_ran_chisq_pdf(x,nu) to return correct result of 1/2
       instead of 0 when x=0 and nu=2, and +inf when x=0 and nu<2.

    ** Fixed gsl_pow_int(x,n) to avoid an infinite loop when n=INT_MIN due
       to wrapping of signed integers.

    ** Fixed gsl_sf_hyperg_2F1(a,b,c,x) to avoid returning NaN for
       arguments |a|>10. [bug #24812]

    ** Avoid spurious underflow return code in gsl_sf_beta_inc_e when
       intermediate underflow does not affect the result. [bug #30933]

    ** Avoid segfault in Chebyshev series derivatives gsl_cheb_calc_deriv
       for n=1. [bug #29139]
