This CL moves candidate.h into the public API, since it has been implicitly included before. This is a straightforward way of solving the circular dependencies involving that file. For instance, libjingle_peerconnection_api includes candidate.h from jsepicecandidate.h, but _api can't depend on rtc_p2p, which depends on _api. In fact, _api can't depend on much at all since it's a very high level abstraction; instead, things should depend on it. Furthermore, we have the case where deprecated headers include headers in internal modules. I just have to turn off include checking for those, but that's not a big deal. This CL punts the problem of callfactoryinterface.h being implicitly included, and pulling in most of the call module with it. This should be addressed in a follow-up CL.
