needed.

According to private conversation with Francois Bissey, #9976 has
introduced a problem that makes it impossible start sage-4.7.1 on Gentoo.
That's pretty serious, and so this ticket is a blocker.
The problem is that sage_wraps reads the sources of to-be-wrapped
functions and methods. The sources are stored as an attribute to the
wrapper, which, on the one hand, is a waste of memory. Worse: Reading the
Cython sources is impossible for sage-on-gentoo. Therefore, sage can't
start.
My patch introduces some lightweight classes, that simply store a
reference to an object (e.g., the to-be-wrapped function) and return the
sources or source lines or the argument list ''only when called''.
