This patch tries to move them to `ContentParent` instead.
`ProcessPriorityManagerImpl::ObserveContentParentCreated` could not be moved
due to using `do_QueryInterface` to cast from a `nsISupports` down to the
`ContentParent` object. This could be fixed to remove the interfaces entirely,
but I left that for a follow-up.
Depends on D20549

The total size of an IPC inputStream message must be less than 1mb. When we
compose the message for the multiplex stream, each sub stream collaborates with
its own size, deciding if it's better to be a pipe stream (IPCRemoteStream) or
a full serialized one.

Before this patch, IPCStream was an union containing IPCRemoteSteam or an
InputStreamParamsWithFds. Now InputStreamParamsWithFds is renamed IPCStream and
IPCRemoteSteam is one of the possible InputStreamParams structs.
Before this set of patches, the decision of exposing the stream as a pipe was
centralized in IPCStreamUtils, based on the total expectation size of the IPC
message. This triggers issues when multiplex inputStreams contain something
that cannot be sent as a pipe (IPCBlobInputStream, for instance), or something
that it's better to do not set as a pipe (nsFileInputStream), together with
memory streams (nsStringInputStream), which could make the IPC message greater
then what accepted (1mb).
These patches move the "pipe vs non-pipe" choice into the single inputStream
implementation.
