lib, ipcp: Revise fast path and flow interfaces

IPCPs can now use ap_init() to initialize the memory. All flows are
accessed using flow descriptors, this greatly simplifies IPCP
development. Reverts the fast path to a single ap_rbuff per process.
Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev.  Adds a lib/shim-dev
holding tailored functions for shims.  Moves the buffer_t to utils.h.
Fixes the shim-eth-llc length field.  Removes the flow from shared.h.

Fixes #4
Fixes #5
