Provisional ticket for the next big Pynac update.
* libgmp `bigint`s and `bigrat`s instead of `ZZ` and `QQ` Python objects
* assumptions/domains can influence Pynac computation
* C++11 results in better code readability
* better decisions through more info flags and logic
* return `not implemented` and `undecidable` for some decisions (for
matzh. logic changes see #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

Comment:
This works and can be reviewed independently on machines with gcc>=4.6,
but please wait with setting positive for the build system changes (i.e.,
#19298).
There are two failing doctests: one only happens on doctesting and needs
the associated environment; the other is the "pi in RIF" doctest which
presented a philosophical problem to Sage developers (see #17984) and thus
cannot be resolved in my lifetime.
