[liblo] regarding recent issues on 64-bit

So the good news is that my job recently provided me with a shiny new
macbook pro, which I've got Linux and OS X (and eventually Windows)
running on.

Finally, I can test liblo under a variety of conditions, including for x86_64.

The bad news is that when I run "make test" for the current master
using Ubuntu 13.04, I get the following:

TEST SUCCESSFUL

In other words, I don't seem to be able to reproduce many of the
issues people have been having with the 0.27 release.  (Other than the
fact that "make test" was hanging, which is now fixed in master.)

Any ideas on how I could approach this?  If anyone still experiencing
issues with the current master on any operating system could please
report it would be appreciated.

To do:

- remove SO_REUSEPORT
- check that ABI is backward-compatible replacing the .so
  (should i add back the lo_server_recv_raw_stream symbol ?)
- remove some configure-generated files from the tarball
