squid 3.4.14: latest patches, sorted options

  The 'configure'-options were sorted (kind of) to get a better overview.

Added latest patches from upstream.

Changed '--enable-async-io=8' to '--enable-async-io=16' because of
http://www.squid-cache.org/mail-archive/squid-users/200705/0768.html :

"The default number of threads is dependent on the number of aufs
cache_dir lines, based on a reasonable estimate of how the code behaves."

Hi,

I will merge this this time, but please do these things in several commits in
the future.

Best,
