Add SHA512 digests for distfiles for math category

Problems found locating distfiles:
	Package dfftpack: missing distfile dfftpack-20001209.tar.gz
	Package eispack: missing distfile eispack-20001130.tar.gz
	Package fftpack: missing distfile fftpack-20001130.tar.gz

	Package py-sympy: missing distfile sympy-0.7.6.1.tar.gz
	Package quadpack: missing distfile quadpack-20001130.tar.gz

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Upstream changes:

Released December 31, 2013

Linear algebra:
* added qr() for matrix QR factorization (contributed by Ken Allen)
* added functions eigsy(), eighe(), eig() to compute matrix
  eigenvalues (contributed by Timo Hartmann)
* added functions svd(), svd_r(), svd_c() for singular value
  decomposition of matrices (contributed by Timo Hartmann)
* added calculation of Gaussian quadrature rules for various weight
  functions (contributed by Timo Hartmann)
* improved precision selection in exp_pade() (contributed by
  Mario Pernici)

Special functions:
* fixed ellippi() to return an inf instead of raising an exception
* fixed a crash in zeta() with huge arguments
* added functions for computing Stirling numbers
  (stirling1(), stirling2())
* improved the computation of zeros of zeta at high precision
  (contributed by Juan Arias de Reyna)
* fixed zeta(-x) raising an exception for tiny x
* recognize when lerchphi() can call zeta() or polylog(),
  handling those cases faster

Compatibility:
* fixed gmpy2 compatibility issues (contributed by Case Van Horsen)
* better solutions for python 2/3 compatibility,
  using Benjamin Peterson's six.py
* fixes to allow mpmath to run in non-sage mode when sage is available
* support abstract base classes (contributed by Stefan Krastanov)
* use new-style classes to improve pypy performance

Other:
* added Levin, Sidi-S and Cohen/Villegas/Zagier series
  transformations (contributed by Timo Hartmann)
* added isfinite() utility function
* fixed a problem with bisection root-finding
* fixed several documentation errors
* corrected number of coefficients returned by diffs() with
  method='quad'
* fixed repr(constant) being slow at high precision
* made intervals hashable

Log message:
Mark packages that are not ready for python-3.3 also not ready for 3.4,
until proven otherwise.

Log message:
Mark packages as not ready for python-3.x where applicable;
either because they themselves are not ready or because a
dependency isn't. This is annotated by
PYTHON_VERSIONS_INCOMPATIBLE=  33 # not yet ported as of x.y.z
or
PYTHON_VERSIONS_INCOMPATIBLE=  33 # py-foo, py-bar
respectively, please use the same style for other packages,
and check during updates.

Use versioned_dependencies.mk where applicable.
Use REPLACE_PYTHON instead of handcoded alternatives, where applicable.
Reorder Makefile sections into standard order, where applicable.

Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default
with the next commit.

Whitespace cleanups and other nits corrected, where necessary.

Log message:
"user-destdir" is default these days
