Improved logging of HTTP requests

- MemoryBuffer isn't seekable, so we can't log it. Log the string instead.
- Handle compressed streams
- Don't attempt to dump binary data. Either don't log it at all (if we know it's binary), or at least convert non-ASCII characters to ASCII.
- Log responses to HTTP requests
- Use the same log prefix for all of these log messages ("[LOGHTTP]"), to make them easy to see at a glance
- Increased the snippet length to 200 (80 doesn't show enough), and add "..." only if the message was actually truncated
