ppapi can't depend on content.

[Yufeng Shen (Slow to review), 2014/05/13 00:16:15]

I am not sure how to do this correctly.

so currently latency_info's ipc traits is in 
content/common/content_param_traits_macros.h

If I just copy the IPC traits stuff over from content_param_traits_macros.h,
there will be redefinition error
because ppapi_messages.h collides with content_param_traits_macros.h
in a non-nacl build.

Also I can't move the IPC traits into ui/events/ since that will
add dependency of ui on ipc.
