logging patch

[curl] CurlRequestScheduler thread runs busily while all active handles are paused to wait for completeDidReceiveResponse

1. Apply the logging patch and compile WinCairo WebKit
2. Remove the cache directory manually
   C:\Users\<username>\AppData\Local\Apple Computer\WebKit
3. $env:WebCoreLogging = "Network"
4. Start WinCairo WK2 MiniBrowser
5. Go to https://www.asahi.com/
6. Server Trust Evaluation Request dialogs are popped up
7. Close the dialogs
8. Wait for finish loading
9. Check the log

The log contains a lot of maxfd=-1 lines.

> CurlRequestScheduler::workerThread maxfd=-1 rc=0
> CurlRequestScheduler::workerThread activeCount=1
> CurlRequestScheduler::workerThread maxfd=-1 rc=0
> CurlRequestScheduler::workerThread activeCount=1
> CurlRequestScheduler::workerThread maxfd=-1 rc=0
> CurlRequestScheduler::workerThread activeCount=1
