Fixes to clustering, that caused an assert to trigger after the stats changes [TS-519].
Make the checks when to honor the Content-Length: header less strict, against origins without Keep-Alive [TS-507].
Eliminate old ssl_ports feature, it's completely replaced with the connect_ports configuration [TS-517].

Experimental supoprt for a dedicated DNS thread. This can be enabled with the records.config option CONFIG proxy.config.dns.dedicated_thread INT 1
This feature is possibly useful for very busy forward or transparent proxies [TS-307].
Accept threads can leak some amount of memory. This patch also supports multiple accept threads (very experimental!) [TS-496].
HttpSM has an assertion that checks the client URL against the cache URL, which breaks INKSetCacheUrl [TS-495].
Return value from pcre_exec tested incorrectly [TS-493].
Improved loop detection using the Via header [TS-490].
Fixes for Solaris build (yay, it builds!).
Remove filter.config remnants [TS-486].

Make it possible to "write" Content-Length headers > 2GB [TS-471].
Better support for Age: headers, and avoiding overflows [TS-470].

In Cache.cc, make snprintf() around Debug statements conditional for performance [TS-459].
Cleanup / optimize Via: string generation [TS-460]. Also make the default for Via: on responses to be disabled (it can leak info).
