New description:
The next big Pynac update has:
* libgmp `bigint`s and `bigrat`s instead of `Integer` and `Rational`
Python objects
* assumptions/domains can influence Pynac computation
* sync elementary assumptions on symbols/functions with Pynac (#19035)
* C++11 results in better code readability
* better decisions through more info flags and logic
* return `not implemented` and `undecidable` for some decisions (for
math. logic changes see the #19040 description)
* add inexact flag for possible expansions / FP simplifications
* `abs()` expansion
* `function::info()`
* from GiNaC: Fix `pow(+(...),2).expand()`
* remove some unused files and other cleanup; add missing autoconf macro;
* some older memleaks closed
