Sometimes the receiver thread got the SDU before the writer thread has
set the sent time when testing over the local. The sent time is now
written before actually sending to avoid this.

Receiver timeouts can now be set on a flow using the flow_set_timeout
function. Specifying NULL disables the timeout. The flow_get_timeout
function gets the value for the timeout.
This commit also deprecates fcntl in favor of flow_get_flags and
flow_set_flags functions.
struct qos_spec is typedef'd as a qosspec_t.
The tools and cdap.c are updated to use the new API.
Fixes a bug in operf client where the client's writer thread wouldn't
cancel on SIGINT.

size_t is 32 bits on those machines, failing as an argument to
printf. Some variables in oping and operf were changed to uint32_t and
uint64_t to avoid issues.

If alloc_res fails all resources will be cleaned, except for the
assigned flow_descriptor, which must be released with a dealloc call.
Calling dealloc after a failed flow_alloc will not try to destroy the
already cleaned up flow in the IRMd and IPCPs.
Also fixes some memleaks in the oping client.

This has the code checked with -Wcast-qual and -Wconversion flags.
These flags were removed because SWIG generated code fails.

This reduces the risk for some bugs, for instance due to
signed/unsigned mismatches and unused variables.

The fast path will now use an incoming ring buffer per flow per
process. This necessitated the development of a new method for the
asynchronous io call, which is now based on an event queue system for
scalability (fqueue). The ipcpd's and tools have been updated to this
API.

The struct flow_set can now be accessed in applications as flow_set_t.
Fixes some malformed lines and homogenizes output when receiving bad
SDUs in the oping tool.

Now correctly handles and drops non-ouroboros traffic.

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

The flow_select call now takes as a parameter a flow_set_t, which
specifies a set of flow descriptors that will unblock the select call
when an SDU for one of them arrives. The select call has been moved to
its own header.

When killing the oping client before it sent an SDU, some bad
operations were being performed.

Ouoroboros ping application mimics the GNU ping application.
