lib: Revise app flow allocation

This revises the application flow allocator to use the flow_info
struct/message between the components. Revises the messaging to move
the use protocol buffers to its own source (serdes-irm).

Adds a timeout to the IRMd flow allocator to make sure flow
allocations don't hang forever (this was previously taken care of by
the sanitize thread).
