    Make .eval() evaluate top-level only.
    
    With the previous patch, some old workarounds have become unnecessary:
    If all expressions are evaluated, any object which is an aggregate of
    expressions will only ever have to evaluate the top level. As such, it
    has become pointless to evaluate child objects of an expression prior
    to doing its own term-rewriting. This patch removes the evaluation of
    children from all GiNaC objects. It also removes the now superfluous
    parameter 'level' of the eval methods.

commit ae6c004bd31e02dda37357d74b641c101b116c73
Author: Richard Kreckel <kreckel at ginac.de>

    Make add::eval(), mul::eval() work without compromise.
    
    If a user asks to evaluate an object, the expectation is that the
    library returns an evaluated, canonical expression. Everything else is
    a bug. (It doesn't matter whether the user asks explicitly or by
    assigning to an ex.) It turns out that it was possible to construct
    objects which didn't fully evaluate. This patch fixes this by making
    eval() a little bit more careful.
    
    This obsoletes the need to go through combine_ex_with_coeff_to_pair()
    when constructing an epvector that is then used to construct an add
    or mul. (Alas, this was omitted frequently enough...)
