Nick Mathewson 668f7a2639 Do not send Libevent log messages to a controller (0.2.1 backport)

Doing so could make Libevent call Libevent from inside a Libevent
logging call, which is a recipe for reentrant confusion and
hard-to-debug crashes.  This would especially hurt if Libevent
debug-level logging is enabled AND the user has a controller
watching for low-severity log messages.

Fix bug 2190; fix on 0.1.0.2-rc.

   o Minor bugfixes
     - Prevent calls from Libevent from inside Libevent log handlers.
       This had potential to cause a nasty set of crashes, especially if
       running Libevent with debug logging enabled, and running Tor
       with a controller watching for low-severity log messages.
       Bugfix on 0.1.0.2-rc.  Fixes bug 2190.
