LGTM. A minor comment: |

@berkerpeksag thanks! I guess we should do that for all similar messages. Let's do that in another commit if needed :) |

This makes it a bit easier to debug than just logging the fact that there was an exception. Also restore logging in the URI-less case, since that was broken in 79011d0 (Include request URL in error message, 2015-07-08, benoitc#1071) but not restored in 1ccebab (prevent crash when reporting an error, 2016-03-22, benoitc#1231).

The argument is documented in [1], and we've been using it in some cases since 410bcfa (Fix statsd logging to work on Python 3, 2015-04-20, benoitc#1010). This commit goes through all of our log calls and makes sure we're using it consistently. For more examples of using exc_info instead of direct traceback calls, see 0acfb55 (Let logging module handle traceback printing, 2016-02-05, benoitc#1201). The traceback call I'm removing snuck in later with f4842a5 (Log exception occurring during worker exit, 2016-05-04, benoitc#1254). I'm removing the "Error processing SSL request" debug messages, because those will be handled by the subsequent handle_error call. We've had them, for reasons that I'm not clear on, since 1198cc2 (handle ssl connections, 2012-12-14). I've restored logging in the URI-less Worker.handle_error 500 case, since that was broken in 79011d0 (Include request URL in error message, 2015-07-08, benoitc#1071) but not restored in 1ccebab (prevent crash when reporting an error, 2016-03-22, benoitc#1231).

Tests for the lines I've touched may be more trouble than they're worth. I've worked up one for a broken worker_exit hook to show what they look like, but left the others untested for now.
