Backup most of the changes to the event library. At this point the only

remaining changes are in event.c and event.h, plus everything in the
WIN32-Code directory. I still have to find a way to make it working on
Windows without these changes, but I have good hopes. However, the
the code in WIN32-Code will have to stay there as it's more stable
than the one provided by the libevent project.

This commit was SVN r11386.
