Support unix domain sockets for memcached

[oschaaf]

From https://groups.google.com/forum/#!topic/ngx-pagespeed-discuss/XBEopX--kH8
I would be nice to support unix domains for memcached.
Looking at apr_memcache2.c, I don't think it would be very hard to add it.

@jeffkaufman to support this, a change is required in /src/third_party/aprutil/apr_memcache2.c [1]

Can I look at adding that? Or are unix sockets deliberately not supported?

This would be nice to add, but I think it makes less sense for you to do it than someone who can change third_party/aprutil/apr_memcache2.c. That way both nginx and apache get support.

We should probably look at the diffs for apr_memcache.c and our apr_memcache2.c and see if there are any other changes we need (or, really, if there are any other changes we don't need).
