/*++
CloseConnectionSocket - close the socket.
This method is called when we want to close the conection.
It must be called with the critical section held.
The key thing about this method is that it's only called
when we know that we don't have an async read pending with
the socket, either because we're being called from the read
callback or we're called after an error from a user read (the
user read couldn't have happened if we have a read down).
Because of this it's OK for us to null out the socket and
let the next caller try to autoreconnect. This makes life
simpler, all connection closes (either ours or server
initiated) eventually go through here. This is also the
only place that can null out the socket - if that happens somewhere
else, we get into a race condition where an autoreconnect can happen
while we still have a receive buffer down, which could result in
two buffers at once.
As to what we do: we loop through our write list and pull requests
off it, and give each request an error failure. Then we close the
socket and null out our reference, and go ahead and let the next
request go.
Input:
status - WebExceptionStatus indicating the reason that this method
was called. This may be WebExceptionStatus.Success,
indicating a normal shutdown.
Returns:
Nothing.
