Subject: [PATCH] ofproto: make binary code loadable
I've been using the latest RYU source from GIT, and building my own python
eggs. When launching ryu-manager, I get the following error:
[root@hostname ryu]# ryu-manager
Traceback (most recent call last):

I found that I could execute ryu-manager correctly from the interactive
python shell but not from the command line, and looked at the derivation of
Event classes from pathnames.
It occurred to me that the eggs would not necessarily include the source
files, so I tried successfully to make the code look up both source and
compiled filenames, and return the union of that.
