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.
Fixes #20.

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 PR enhances the shared memory providing recovery if a process
crashes. It adds a SHM_DU_TIMEOUT_MICROS variable, setting an
expiration time for SDU's when shared memory is full. If an
application doesn't read a blocking SDU within this time, the shared
memory will be cleansed of all SDU's for this application and the
application's rbuff will be cleared.
Some refactoring of the API's. Fixed wrong pthread checks in IRMd.

Changes the variable name as well to API instead of PID.

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.
Fixes #12

This adds error numbers specificly for Ouroboros. It also refactors
some of the header files that are installed.

Update to POSIX 200112L to allow use of robust mutexes in the
shm_du_map. Removed the implementation of the rw_lock in favor of
pthread_rwlock_t.
Placeholder for the shm_du_map_sanitize function.

The ipcpds didn't unlock the flows lock when the dst_name is
unbeknownst to the IRMd.

Now correctly deallocates the local fd if the remote already
deallocated the flow.

The registration function has been moved to the irm tool, applications
now need to be registered by an administrator. Currently only supports
one instance per registered name, and an AP can be registered under
only one name.
The irmd can now start a registered server application on demand.
For the full functionality of the tool, execute "irm register".
AP name removed from flow allocation. Flow allocation does not send
the source ap name as it is quite useless. The accept() call now only
returns the AE name.

This stops IPC processes from hanging due to bad locks. It first
informs all threads that the IPCP is shutting down, then cancels all
threads. Cancellation is still required because threads may be in
accept() or receivefrom().

This introduces an IPC process that relays data between two local AP's
over the shm_du_map. Only configuration it has is a DIF name.
It required small modification elsewhere:
lib: added support for the IPCP_LOCAL type
irm: added support for the IPCP_LOCAL type
dif_config: added the IPCP_LOCAL type
tools: added support for the IPCP_LOCAL type
