Summary: GetProcAddress has no use right now

Initial Comment:
win32api.GetProcAddress() should be either removed or
has some counterpart that will allow to call arbitrary
functions with specified parameter types.

Don't remove it; it's useful for writing simple scripts that read and
simple information about DLLs.

For example, I work on a project that has three different kinds of
loadable plugin modules, where each plugin is just a DLL with a pair of
specific exports (factory function and cleanup) with a name that indicates
the type. There are three different types of plugins. 

My script opens a DLL and uses GetProcAddress to find whether it's (a) a
valid plugin of one of the three types, (b) not a valid plugin of any type,
(c) ... because whoever built it forgot extern "C", or (d) not even a DLL.

Sure, I could do the same thing with ctypes (and actually call the code),
but I've already got some working scripts today.
