math/py-sympy: Update to 1.5.1

Changes:
- Fix a regression in 1.5 that allowed expressions to compare equal to
  strings, and caused == to call str() on the other object.
- Avoid using scipy versions of numpy functions, which are deprecated,
  in lambdify.

Take MAINTAINERship.

all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
math/py-sympy: Update to 1.5

Breaking changes:

- Deprecate is_EmptySet in favor of is_empty.
- Lambda now requires a tuple rather than a list for the signature
  argument (non-tuple iterables are deprecated)
- Eq(expr) now raises ValueError. Eq(expr, 0) should be used
  instead.
- Refactory of the units module. Scale factors and dimensions are now
  both global and relative to single unit systems.
- get_dixon_matrix() now computes only the necessary monomials for the
  Dixon matrix.
- The ProductSet of no sets is no longer the empty set. Instead is the
  set consisting of the empty tuple.
- Deprecated tensorhead() and tensorsymmetry() static methods.
- Rational, irrational, transcendental and algebraic now imply finite
  in the assumptions system. This means that all symbols declared as
  rational, integer, odd etc are now automatically assumed finite.
- In the (old) assumptions, complex=True now implies finite=True. Note
  that the default assumption for Symbol is complex=None, which allows
  for the possibility for it to be infinite.
- The assumptions system is changed so that only finite numbers can be
  considered real, positive, negative, nonnegative, nonpositive or
  nonzero (since nonzero implies real). This means that any symbol
  declared with e.g. real=True is now automatically considered
  finite. It also means that infinities can not be considered positive
  or negative since they are not real (e.g. oo.is_positive is now
  False).
- New assumptions extended_real, extended_positive etc are added that
  allow for positive and negative infinity. The equivalent of
  Symbol('x', real=True) in version 1.4 is now Symbol('x',
  extended_real=True). The equivalent of Symbol('x', negative=False)
  is now Symbol('x', extended_negative=False) although it is usually
  better to use Symbol('x', nonnegative=True) (which implies both
  real=True and finite=True as well). Code that previously checked if
  x.is_positive should now be written as if x.is_extended_positive if
  it is intended that infinities should be allowed.
- Numbers still compare the same as they do in Python (Float(1) == 1)
  except when they appear in an Expression, e.g. x**2.0 != x**2

Log message:
math/py-sympy: Update to 1.4

Highlights:

* Logic expressions with relations can now be simplifed in a better
  way which has impact on e.g. simplification of piecewise
  expressions.
* The MathML Presentation printer has seen a major improvement with
  support configuration and about a hundred new functions.
* Union and Intersection have been improved to, among other
  improvements, support Python sets.
* The test procedure has been changed to include code coverage and
  code quality checks leading to a number of issues being identified
  and removed.
* Unicode support, especially for Python 2.7, has been improved.
* subs and Subs have been improved in a number of ways.
* SymPy objects now renders as LaTeX automatically in Jupyter
  notebooks. init_printing is still required to LaTeX render non-SymPy
  objects such as lists of expressions or Python ints.

Log message:
math/py-sympy: Update to 1.3

Backwards compatibility breaks and deprecations:

    * Symbols no longer automatically convert to functions when called,
      e.g., if f = Symbol('f'), f(t) is now a TypeError. To create a
      function, use f = Function('f') or f = symbols('f', cls=Function).

    * .integrate() has been renamed to .compute_expectation() in
      sympy.stats in order to avoid confusion with the integrals module.

    * classof() and a2idx() in sympy.matrices.matrices have been
      deprecated in favor of the same functions in sympy.matrices.common.

    * The source() function has been deprecated. Use inspect.getsource or
      ?? in IPython.

Log message:
Update py-sympy to 1.2

Highlights

   There are many changes in 1.2 (see below). Some of the highlights are
     * Python 3.3 is no longer supported. If you require Python 3.3
       support, use SymPy 1.1.1. See our [518]policy on dropping support
       for major Python versions.
     * Experimental LaTeX parsing with sympy.parsing.latex.parse_latex()
       has been added, based on the latex2sympy project. This requires
       antlr-python-runtime to be installed. [519]#13706
     * The vector module has been improved to support orthogonal
       curvilinear coordinate systems ([520]Szymon Mieszczak's GSoC
       project)
     * New module sympy.integrals.intpoly for integrating uni/bivariate
       polynomials over 2-polytopes. ([521]Arif Ahmed's GSoC project)
     * Improvements to the code generation module. ([522]Bj?rn Dahlgren's
       GSoC project)
     * Improvements to the group theory module. See below for more
       information. ([523]Valeriia Gladkova's GSoC project)
     * New module sympy.discrete for operating on discrete sequences.
