Log Message:
Update py-mpmath to 0.14.
per update request from Wen Heping by PR#42755.

Pkgsrc changes:
* Set LICENSE
* correct EOL style of installed files
* Add self-test target

Changes:
--0.14--
Released February 5, 2010

General changes:

* Fully separated the code into "low-level" and "high-level", permitting the
  use of alternative contexts (the mpmath.mp object provides the default
  implementation)
* Implemented a context for fast double-precision arithmetic using Python
  types (mpmath.fp)
* Implemented hooks for importing a faster version of mp arithmetic from Sage
* Implemented optimized fp versions of certain functions (including erf, erfc,
  gamma, digamma, ei, e1)
* Renamed and reorganized various internal modules and methods (including
  merging low-level modules into mpmath.libmp). This should not affect most
  external code using top-level imports.

Plotting:

* Implemented splot() for 3D surface plots (contributed by Jorn Baayen)
* Permit calling plot functions with custom axes (contributed by Jorn Baayen)

Matrices:

* Fixed lu_solve for overdetermined systems (contributed by Vinzent Steinberg)
* Added conjugate matrix transpose (contributed by Vinzent Steinberg)
* Implemented matrix functions (expm, cosm, sinm, sqrtm, logm, powm)

Miscellaneous:

* Prettier printing of numbers with leading zeros at small precisions
* Made nstr pass on kwargs, permitting more formatting options
* Fixed wrong directed rounding of addition of numbers with large magnitude
  differences
* Fixed several docstring typos (contributed by Chris Smith)
* Fixed a bug that prevented caching of quadrature nodes to work optimally.

Special functions:

* Implemented fast evaluation for large imaginary heights of the Riemann zeta
  function, Z function and derived functions using the Riemann-Siegel
  (contributed by Juan Arias de Reyna)
* Unified the zeta() and hurwitz() functions, automatically selecting a fast
  algorithm
* Improved altzeta() to fall back to zeta() for large arguments
* Fixed accuracy of zeta(s) for s ~= 1
* Implemented exact evaluation of Euler numbers (contributed by Juan Arias
  de Reyna)
* Implemented numerical evaluation of Euler numbers and Euler polynomials
  (eulernum(), eulerpoly())
* Fixed bernpoly() and eulerpoly() to compute accurate values for large
  parameters
* Fixed accuracy problems for hypergeometric functions with large parameters
* Faster evaluation of hypergeometric series using on-the-fly code generation
* Optimized hypercomb to detect certain zero terms symbolically
* Removed the djtheta function (jtheta() accepts a derivative parameter)
* Implemented li(x, offset=True) to compute the offset logarithmic integral
* Fixed wrong branch in Lambert W function for certain complex inputs
* Implemented the reflection formula for the Barnes G-function,
  superfactorials, hyperfactorials, permitting large arguments in the left
  half-plane
* Implemented analytic continuation to |z| >= 1 for hypergeometric functions
  pFq with p=q+1; added hyp3f2()
* Implemented Borel summation of divergent pFq functions with p > q+1
* Implemented automatic degree reduction of hypergeometric functions with
  repeated parameters
* Added convenience functions expj(), expjpi()
* Use Mathematica's convention for the continuation of the Meijer G-function
* Added phase(), polar(), rect() functions for compatibility with the
  Python 2.6 cmath module
* Implemented spherical harmonics (spherharm())
* Optimized ci(), si(), chi(), shi() for complex arguments by evaluating
  them in terms of ei()
* Optimized hyp2f1 for z ~= -1
