new server snapshot

[Brad Fitzpatrick]

Here's another pre-1.1.9 snapshot:

http://www.danga.com/memcached/dist/snapshots/memcached-1.1.9-snapshot.tar.gz

We're now running it on one LiveJourna machine and it seems
fine.  The changes are really minimal from 1.1.8.

Changes since last snapshot:

* It's much faster, using TCP_CORK on Linux, TCP_NOPUSH on BSD, and
  TCP_NODELAY everywhere else.

Change since 1.1.8:

* Portability fixes for BSD/OS X.

Known issues:

* autoconf needs to --disable-static on OS X, because Darwin doesn't
  support static binaries.
