Update to Maxima 5.20.1.

Approved by <agc>.


   Backwards-incompatible changes:

 * removed package jtroot3 (superseded by bfallroots)

 * internal symbols of specint replaced by more descriptive names:

    %f         --> hypergeometric
    %e         --> elliptic_ec
    %kelliptic --> elliptic_kc
    %p[a,b,c]  --> jacobi_p
    %p[a,b]    --> assoc_legendre_p
    %p[a]      --> legendre_p

    %ei        --> expintegral_ei
    %h[n,x]    --> hankel_1 and hankel_2
    %he        --> hermite


   New items in core:

 * general mechanism for functions to distribute over operators
   (distribute_over declaration)


   Other revisions:

 * improved Laplace transforms of special functions

 * assume database:

   The inferences between the declarations of variables as integer,
   real, complex, .. have been cut out. The constant %i is declared
   to be imaginary. The constants %pi, %e, %gamma, %phi are declared
   to be real.

   The database handles expressions with constants more completely.
   Facts like assume(x < %pi/2) are now handled correctly.

   The sign of sums of constant expressions is determined more
   correctly.

   Askinteger take into account more facts from the database.

 * improvements of special functions:

   More functionality for the Hankel 1 and 2 functions:
   Expansion for a half integral order has been implemented.

   More consistent numerical evaluation of Bessel and Hankel functions.

   More general integrals for Bessel functions and implementation of
   integrals for the Airy functions.

   Gamma function accepts a Taylor expansion as an argument.

   Implementation of Struve H and L functions:
   Numerical evaluation for real and complex numbers in float and
   bigfloat precision. Handling of specific values. Derivatives of the
   functions and expansion for a half integral order is implemented.

   Adding mirror symmetry for the Airy functions.

   Improving the limits of the log and factorial functions.

 * package fft: revised for greater speed
 * package to_poly_solver: improvements
 * regularize error and warning messages, and translate via gettext (ongoing)
 * bug fixes and other improvements in plotting code
 * bug fixes in translator

Updated maxima to 5.9.2.

Significant changes from Maxima 5.9.1 to 5.9.2, in no particular order.
Magnitude of changes varies widely.

 * Parser is now entirely case sensitive, built-in keywords and
   variables are all lowercase only
 * Regularize case in printed messages
 * Improved TeXmacs interface, 2-d input
 * Moved nset (finite set functions) into Maxima core
 * Ported Mersenne twister rng to Maxima core
 * English reference manual revised (form and content)
 * Reference manual translated to Spanish and Portuguese
 * Additional tutorial documents
 * Discrete plots (for plot2d)
 * Enhancements to tensor packages (Atensor, Ctensor, Itensor)
 * Replaced Airy functions with much more extensive implementation

 * Revisions to Bessel functions
    o Bessel functions with real order and complex argument can be
      evaluated numerically.
    o bessel_j can be computed for negative real order.

 * Revisions to gamma function
    o Gamma function can be numerically evaluated for complex arguments.

 * Revisions to elliptic functions
    o Bugs 1165488 and 908185 fixed.
    o Fixed issue where many of the routines were returning single-float
      results instead of double-float when given rational args.
    o elliptic_f with complex args can be numerically evaluated.
    o Other inverse Jacobi routines can be evaluated at complex points.

 * Extensive revisions to hypergeometric functions
    o Adjusted routines to return the new names for the Bessel functions
      (like bessel_j instead of %j).
    o Similarly, any orthogonal polynomials now use the naming
      conventions used by the specfun orthogonal polynomial package.
    o Corrected many errors in implementation.
    o Some missing internal functionality added.
    o Bug 1155241 fixed.
    o Bug 1097915 fixed.
    o Branch cuts for various relationships between hypergeometric
      functions and Legendre functions were implemented or corrected.

 * Revised kill function (fixed several bugs, helps test suite run correctly)
 * Revised code to run test suite
 * Display noun forms 'for and 'if correctly
 * Display if -- then -- elseif correctly
 * Adjust placement of newlines between output lines
 * Establish configuration variable *MAXIMA-TEMPDIR*, make use in plotting
 * Cleaned up autoload declarations
 * Source code lowercase
 * Regularize use of packages in Maxima core
 * Misc code cleanups incl. sloop -> ANSI loop, rename private let and let*
 * New share files:
    share/defstruct.lisp:   define structured objects, also multiple assignment
    share/contrib/descriptive/: descriptive statistics
    share/contrib/diffequations/tests/: several new tests
    share/contrib/distrib/: probability distributions
