Refactored out the child behavior from mpm_winnt. This is the first
step in making a legible multiprocess windows mpm, or at least
structuring the code to always begin a new child as an old one is
going to die soon, rather than waiting for it's final dying breath.
The only code that had to be affected [due to the split and general
structure of the code] was merging the set_listeners_noninherited()
code directly into the get_listeners_from_parent code, and also into
the apr socket.c code for winnt. For the most part the code split
rather nicely.
