Upgrade to pynac-0.6.4

[rwst]

Newest pynac does:

• fix Re/Im(tanh) (doctest fix for: Re/Im(tanh) wrong formula #20098) (R. Stephan)
• fix positive+integer assumption conflicts (add symbolic domains posint, cinteger, crational #20132) (A. Thakkar)
• from GiNaC: [bugfix] fix elusive bug in quo, rem,... (R. Kreckel)
• from GiNaC: [bugfix] fix sqrfree(poly) for zero polynomials in disguise. (R. Kreckel)
• sin/cos/tan of numeric: reduce mod 2*pi (test improved evaluation of trigonometric functions and complex exponential function #20099) (B. Hackl)
• more trigonometric simplifications (test improved evaluation of trigonometric functions and complex exponential function #20099) (B. Hackl, R. Stephan)
• always expand function arguments (B. Hackl)
• exp of numeric: reduce mod 2*pi*I (test improved evaluation of trigonometric functions and complex exponential function #20099) (B. Hackl)
• performance: speed up sin/cos/tan/coth/acoth evaluation (R. Stephan, A. Thakkar)
• performance: GiNaC functions for coth/sech/csch/acoth/asech/acsch (R. Stephan, A. Thakkar)
• AUTHORS updated

The interface changes on this ticket are relatively straightforward, and I could easily review this. However, I'm not sure whether I should, as I've contributed to the pynac release. What do you think?

In principle I have already had a look at your changes, but I would like to see a third opinion as well.

The whole point of this doctest is lost:

        Here arccoth doesn't have 1 in its domain, so we just hold the expression:

            sage: elliptic_e(arccoth(1), x^2*e)
            elliptic_e(arccoth(1), x^2*e)

I would remove the sentence "Here arccoth doesn't have 1 in its domain, so we just hold the expression:"

Unless I'm missing something, this doctest looks gone:

            sage: diff(asech(x), x)
            -1/((x + 1)*x*sqrt(-(x - 1)/(x + 1)))
