commit 65c25b89d9077b9976998da7e9ff3b8d40bcf99d

Move cc::RingBuffer to //base

It is used by content/browser/tracing/arc_tracing_agent_impl.{cc,h}, which,
logically, should not depend on chrome compositor.

Also, we want to move arc_tracing_agent_impl to //chrome/browser
(crrev/c/868575) but we do not want to add a dependency from //chrome/browser to
//cc/base ( https://cs.chromium.org/chromium/src/chrome/browser/DEPS?l=89).

Tracing: Reduce boilerplate code in tracing agents

Since most tracing agents only care about receiving start/stop
tracing signals, a default implementation is provided for other
methods to reduce boilerplate code.
