*) [TS-641] Remove inktomi*.css and some files only referenced by it.
Removing mgmt/html2/charting. Remove the now empty mgmt/html2/tune.
*) [TS-590] Cleanup all SDK APIs to be more consistent. This changes a
large number of APIs, so please check updated docs and signatures in
ts/ts.h. A new tools, tools/apichecker.pl, can be used to help
identifying areas in existing plugins that might need changes.

for when content is cacheable.

code paths

*) [TS-651] Clear all stats when we ask to clear the local stats.
*) [TS-489] Remove the "connection collapsing" feature, it was poorly
implemented, and caused major problem if enabled. We should redo this
