[mod_python] Child process init handler

Mod_perl is able is so this somehow:

PerlChildInitHandler and PerlChildExitHandler do not refer to parts of
the request loop, they are to allow your modules to initialize data
structures and to clean up at the child process start-up and shutdown
respectively, for example by allocating and deallocating memory.
