Commit Message

iproto: allocate service messages from heap

Service messages used for rare, slow-path cases, like handling
disconnection, are built-in internal IPROTO structures. This was
done this way initially because our policy was to do our best to
gracefully handle memory allocation failures. Now, we don't care
about malloc() failures and use xmalloc(), which panics on error,
so there's no point to bother. Let's introduce a special "service"
message for handling these cases and allocate it from the heap.
This will help us introduce custom request processing threads in
addition to tx (apparently, we won't be able to use container_of
macro when we do that so we'll have to store a pointer).
