Summary: Improve I/O redirection to embedding app

Initial Comment:
When embedding Python into an existing application, you
usually do two things (among others):
1. Make Python use your own memory allocation
2. Redirect its I/O to the embedding app

While the former is very easy due to the excellent
pymem.h interface, the latter is quite painful, since
the interpreter uses stdin/out/err directly.

The common workaround I found on c.l.p is providing
your own file-like objects in an extension module and
assign them to sys.stdout/err within the interpreter.
This solution still has its problems (like getting
errors while import site.py)

I wish Python would encapsulate I/O in a similar way
than its malloc interface, and in some way I would
expect this from a language which is said to be 
designed for extending and embedding.

Unluckily I'm not able to this myself. I started my 
first embedding project a few days ago and still miss
the big picture about Python's C API.
