Any complex number can be (un)archived properly.
A complex number can have an exact real part and inexact (floating point)
imaginary part, and vice a versa. Handle these cases properly in the archiving
code instead of bailing out with a bizzare error message.
Thanks to Chris Bouchard for reporting the bug.
NOTE: this fix changes the format of GiNaC archives, so formally it breaks
the binary compatibility. However, "mixed" complex numbers (i.e. ones with
exact real part and inexact imaginary part) can not be archived with previous
versions of GiNaC, so there's nothing to break.

inifcns_nstdsums.cpp: S_num takes cl_N as an argument instead of numeric.
Implicit conversion from cl_N to numeric considered harmful.
Using GiNaC::numeric for numerical computations incurs significant
overhead, so one might want to do these computations using proper CLN
types. Unfortunately, it's not easy due to automatic conversion from
cln::cl_N to GiNaC::numeric. Here is a simple example:
cl_N x, y;
// initialize them
return sin(x) + y*exp(y);
The compiler complains about ambigously overloaded of functions, i.e.
cl_N cln::sin(const cl_N&) versus numeric GiNaC::sin(const numeric&).
Hence, I propose to disable *implicit* conversion from cl_N to numeric
(this can be done by marking the numeric ctor as `explicit').
However, this change happens to be a bit nontrivial, because that evil
conversion is used in GiNaC itself. So, I decided to rewrite those fragments
of code.
