[Bug 986159] [NEW] squid3 open file descriptors limit is set incorrectly

[Timur Irmatov]

Public bug reported:

As far as I can see, upstart configuration file for squid3 tries to
raise limit of open file descriptors to 65535 in pre-start script.
Apparently, this is not working as expected, because squid3 starts and
reports 'With 1024 file descriptors available' in cache.log

Moving ulimit -n 65535 to script section that starts squid itself solves
this. Patch to /etc/init/squid3.conf:
