This commits adds the functions and messages to specify a fixed
protocol syntax during CACEP. It also revises the messages for
specifying the DT protocol syntax from the irm tool.

The header ipcp.h was not installed systemwide, giving compile time
errors when trying to compile external programs that use irm.h. ipcp.h
also included hash.h, which exposes project interal functions. The
enum was moved to ipcp.h to prevent this.

All information passed over the IRMd/IPCP boundary for using IPC
services (flow allocation, registration) is now hashed. This
effectively fixes the shared namespace between DIFs and the IRMDs.
This PR also fixes some API issues (adding const identifiers),
shuffles the include headers a bit and some small bugs.

This adds a header for dealing with endianness in ouroboros. It is
extracted from the byte_order header in the library (which now
includes this header). It also exposes the functions ntohl, ntohll,
htonl and htonll, necessary for converting 32 and 64 bit values for
storage and retrieval from the RIB (which should store multi-byte
values in network byte order).

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.

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.

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.

This adds SWIG to the build and wraps the Ouroboros library so that it
can be called through Python scripts. If either SWIG or Python cannot
be found, no bindings are generated.

This adds the functionality of exchanging the static DIF information
between 2 DIF members. After exchange the enrollment is stopped, and
the IPCP that initiated enrollment transitions to the enrolled state.

This commit introduces a first version of the revised CDAP
specification. CACEP (for authentication purposes) has been separated
from CDAP. Application developers may use CDAP if they find it
useful. Within Ouroboros CDAP will be used to perform operations on
the RIB of an IPCP.

This changes the IRM API after discussions with Dimitri. The register
operation is now split into a bind and register operation. The same
for unregister; unbind and unregister. PIDs are now used as the
application instance name. A name for a PID is only provided for
scriptability in bash. It is therefore also no longer passed down to
the IPCP. Every operation on an IPCP through the IRM API has to use
the PID. Quering of the PIDs by name is possible. The IRM tool has
been updated to use this new API as well. A subcommand 'ipcp' has been
added for operations that take effect on IPCPs only.

The installation prefix was taking a trailing backslash, while it is
common not to do so. Fixed it so that any trailing backslash is
removed by the compilation and installation scripts.

Functionality that was previously thought to be part of the DIF
Allocator is actually namespace management. Hence the file has been
renamed and the API updated.

This sets the correct install directories for all the binaries,
library and header files. It also sets the right permissions on the
sockets and shared memory so that regular users can also use the
ouroboros library. Root privileges are required to run the irmd.

The tool sends constant bandwidth traffic between a client and a

Adds time_utils.h to the library containing useful functions for
arithmetic with timespec and timeval structures.

This fixes wrong header inclusion that would make programs which are
not developed within ouroboros fail upon compilation, since they would
not find certain headers on their system.

This adds the QoS cube definition, which is an enum to select which
QoS is needed in the IPCP. An application has to use the qos_spec in
qos.h to define what it needs. The IRMd will map this unto a qos cube
definition.
Some headers are now also no longer installed on the system, since
they are only to be used within the irmd and ipcps.

This commit has a first implementation of flow allocation (the "slow
path") and read/write (the "fast path") for ouroboros. It provides
basic but unstable communications over the shared memory.
It required a lot of changes all over the stack, and fixes a number of
previously undetected issues.
This PR still need heavy revision regarding data model, locking and
cleanup.
lib/dev: modifications to the API. It now uses an ap_init() call to
set the AP name and sets the Instance ID to the pid of the process. It
also binds the AP to the shared memory and creates tables for mappings
in the fast path. A call to ap_fini() releases the resources.
lib/shm_ap_rbuff: added ring buffer for data exchange between
processes in the fast path. It passes an index in the shm_du_map.
lib/shm_du_map: rewrote API to work with calls from dev.c. Garbage
collector added. Tests updated to new API.
ipcpd/ipcp-data: removed everything related to flows, as these are
universal for all ap's and kept in ap_data (dev.c), or similar structs
for shim ipcps.
shim-udp: added flow allocator and read/write functions and shm
elements.
irmd: revised data model and structures necessary for flow allocation.
tools: echo updated to new dev.h API.
messaging system was updated to comply with new flow allocation
messages. All exchanges use pid and port_id to bootstrap the fast
path.

This adds dif_config to the prototype, in which one is able to specify
the parameters a DIF should have. The bootstrap operation of an IPCP
takes this as parameter and is oblivious to whether it is a shim or a
normal IPCP. The dif_config struct is also correctly serialized and
deserialized and passed opaquely to the correct IPCP. This IPCP is in
charge of deserializing it correctly.

The shared memory map will allow passing SDU's between IPCPs
efficiently. It is a single block of managed memory. SDU's are stored
in a shm_du_buff datastructure, which is a list of blocks inside the
shared memory region. The mechanism for passing SDU's is not yet
implemented and could be either within the region or using another
local IPC mechanism.
The following things are configured at compile time:
SHM_FILE_NAME : the name. Default is "ouroboros_du_map".
SHM_DU_BUFF_BLOCK_SIZE: size of a block inside the shared memory
region. Default is the pagesize of the system.
SHM_DU_MAP_SIZE : the approximate size in bytes of the shared
memory map. The actual filesize may differ by
a small margin. Default is 4MB.

This adds the functionality to create and destroy IPCPs. Upon creation
a new process is forked and execve'd. Upon destruction the IPCP is
destroyed by killing it with SIGTERM.

This adds a build target 'check', which executes a test suite for
every daemon/library. Every test suite consists of a test driver that
executes a function in a file with the same name as the function. The
compile_debug script executes the 'check' target to validate there are
no regressions. Packaging is also fixed and the prototype can be
shipped as a tarball.

Contains the initial build infrastructure. Cmake was chosen for
