Remove some content_child dependency from content_common
content_common does not have an explicit dependency on content_child in the GYP
files, yet depends on symbols from content_child. This causes order-dependent
linker errors on some builds (e.g. win8_aura). Fix this by refactoring
content::ChildThread to remove the need for that dependency, namely:
* Refactor content::ChildThread to allow users to access (and pass around) its
content::MessageRouter member for use in IPC messaging, instead of passing
around the ChildThread itself.
* Remove explicit check for ChildThread in content::VaapiVideoDecodeAccelerator.
* Update DEPS files accordingly.
