Log Message:
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
    share/contrib/plotdf.lisp:  direction field plotting
    share/contrib/sarag/:   real algebraic geometry
    share/contrib/state/:   state variable equations
    share/contrib/unit/:    units of measurement
    share/contrib/Zeilberger/:  hypergeometric summation
    share/linearalgebra/:   linear algebra
    share/numeric/interpol.mac: Lagrange polynomial interpolation
    share/tensor/:  many new examples
