Also: Add new timeouts to NETCON calls impacted by change
Timeout values are able to be set on all hInternet handles, so they should be able to set in a unified way.
Submitting what I have so far for review.
Known TODO: Tests, verify timeouts are set where NETCON is used, verify ULONG vs DWORD usage rules.
-- v5: wininet: unify timeout values closer to hInternet
