This commit sets the UDP buffer to a larger size, as well as adds
an EDNS block to the DNS request passing this size. This allows
DNS servers to return larger responses, and in turn allow c-ares
to avoid TCP fallback due to requests failing because of the lack
of buffer size.
- iosource_mgr can now track write events to file descriptors as well
as read events. This adds an argument to both RegisterFd() and
UnregisterFd() for setting the mode, defaulting to read.
- IOSources can now implement a ProcessFd() method that allows them to
handle events to single file descriptors instead of of having to
loop through/track sets of them at processing time.
