Maple interface completely broken with Maple 11

[williamstein]

This is what we get for not running the optional doctests. Maple 10 still works fine. With Maple 11 the Sage interface is completely totally broken:

sage -t --only-optional=maple devel/sage/sage/symbolic/expression.pyx # 2 doctests failed
sage -t --only-optional=maple devel/sage/sage/symbolic/integration/integral.py # 2 doctests failed
sage -t --only-optional=maple devel/sage/sage/calculus/calculus.py # 1 doctests failed
sage -t --only-optional=maple devel/sage/sage/misc/functional.py # 1 doctests failed
sage -t --only-optional=maple devel/sage/sage/tests/benchmark.py # 5 doctests failed
sage -t --only-optional=maple devel/sage/sage/interfaces/maple.py # 123 doctests failed

The attached patch trac-2120-maple_interface.patch completely fixes all these problems on Maple with OS X. It may partly break things on Linux, maybe. (?) I don't have a good net connection with access to Linux Maple right now for testing, but will someday and then post a followup patch that fixes any issues.

NOTE: This patch vastly improves the robustness of the Maple interface, to put it mildly.

I'll take care of this.

With stock Maple 12 and stock sage-3.3.alpha0 on OS X, here's what happens (total disaster):

I tried today, and

• maple 12 works fine on OS X (for me). Perfect in fact.
• maple 12 on linux, fails totally:

wstein@sage:~$ sage

The second patch rebases the much earlier patch. It makes doctests and the command line work for me on sage.math, but not having maple I need testers on consumer linux distros and especially Mac OS X.
