This adds the intial implementation of establishing management N-1
flows between normal IPCPs. On calling fmgr_mgmt_flow, a management
flow will be setup to a certain destination IPCP. After flow
allocation, the fd is handed to the RIB manager. The flow manager also
listens for incoming flow requests. In case they are management flows,
they are handed to the RIB manager, otherwise to the FRCT.

This adds the initial headers for the normal IPCP. The normal IPCP
consists of 3 main components:
* The flow manager, in charge of managing N and N-1 flows.
* The RIB manager, in charge of managing the RIB
* FRCT: The flow and retransmission control task

This removes the parameter N-1 DIF from the enroll operation. IPCPs
should just allocate a flow to a DIF name and let the N-1 DIF resolve
it.

Correct implementation of allocation for the Protocol Control
Information. Also removes stale code checking for a corner case when
the du map still wrapped multi-block SDU's.

irmd: Prioritize local ipcp for local flows

For locally registered processes, the IRMd will first look for the
local, then the normal, then the shim-udp. It will look for a normal,
a shim-eth-llc and ultimately a shim-udp for non-local destinations.
It does not yet check if a remote destination is actually known in a
DIF.
Fixes #18.

lib: Add lockfile
|

All includes of <errno.h> within ouroboros are replaced with the
ouroboros errno.

The pid of the IRMd is stored in a lockfile in shared memory. This
makes checking if the IRMd is running independent of the
configuration, as previously the IRMd pid was stored at the end of the
shm_du_map, which could not be read by an IRMd that would be compiled
with different configuration options.
Also corrects some unnecessary includes

lib:irmd: Fix logs and irm_create

exit(EXIT_SUCCESS).

The irm_create() function called irmd_destroy before some key values

Writing output to log files is now enabled by default. Logs are
written to <INSTALL_PREFIX>/var/log/ouroboros, which is created on
install. There is a log file for the irmd and one per IPCP. To still
get (colored) output on stdout, provide the --stdout switch when
starting the irmd.

When an application closes the shm_du_map, it will clean all remaining
sdu's for that application. Adds a function to clean the shm_du_map on
close.

The stack used pid 0 (the scheduler) to indicate an invalid process
instance, probably as a leftover from the deprecated application
process instance id. Using -1 is a better solution.

lib: Provide first implementation of revised CDAP

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.
