Log:
Introduce Win32 AcceptFilter handling.
Divided into 3 classes, this implements the first two;
* AcceptFilter 'data' - much as on Unix, accept will not complete
until data is ready to be accepted. Unlike Unix, it will actually
fetch the first bucket full of data from the tcp socket, and this
patch implements passing that bucket into the core net brigade
in front of the accepted socket.
* AcceptFilter 'connect' - just as in Apache 2.2, accept will not
complete until three way handshake is complete and the endpoints
are resolved, and quickly grabs the endpoint addresses using the
AcceptEx API (which some people have problems with). This will
not be the default.
* AcceptFilter 'none' [not yet implemented] - will be the traditional
select/WSAAccept style processing for broken network socket stacks
and more trivial tcp style connections. If AcceptEx appears to be
a problem, the listener will be able to downgrade to 'none'.

I built trunk on XP today. When trying to run it, I get a restart loop
for the child process, and the error log contains repetitions of:

======================================
Since it is my first trunk build on Windows (and don't have VC6), I
could have well made a mistake. Just wanted to let you know the
result, in case you get the same.

This looks like it's trying to downgrade to the not-yet-existing "none"
filter, based on bill's commit comment
Sure, the question is: is it expected to downgrade, i.e. why is there
error 10038 on my system (and how can I debug this). It could be a
systems setup problem, or it could be a code problem.

Rainer
