We often have the pattern where we NULL-check abstime for
pthread_cond_timedwait to call pthread_cond_wait if it is.
Added a __timedwait function to wrap this.

This allows setting the FLOWPEER state on a flow to signal a peer is
unresponsive.

On exit of the IRMd all flows will now be flagged as down, so external
applications will not hang anymore. Note: reads keep work from flows
that are down until there are no more remaining packets in the buffer,
but no more packets can be written.
When the RIB is used, the external application may exit a bit later
than the IRMd, so I added a brief sleep before the IRMd tries to
remove the fuse main directory.

This add an ouroboros/pthread.h header that wraps the
pthread_..._unlock() functions for cleanup using
pthread_cleanup_push() as this casting is not safe (and there were
definitely bad casts in the code). The close() function is now also
wrapped for cleanup in ouroboros/sockets.h.
This allows enabling more compiler checks.

This allows setting the size of the rbuffs in a system independently
of the main packet buffer using SHM_RBUFF_SIZE. The benefit of setting
a smaller rbuff size is that a single process can't fully occupy the
main packet buffer.

This will change SDU (Service Data Unit) to packet everywhere. SDU is
OSI terminology, whereas packet is Ouroboros terminology.

This refactors ouroboros to use "program" instead of "application
process" and "process" instead of "application process instance" to
align with current naming in current Operating Systems courses instead
of the ISO nomenclature adopted by RINA. This change permeates through
the entire implementation. Also contains some minor other refactors.

This refactors the creation of shm_rdrbuff and shm_rbuff elements. All
cleanup is now handled and the common code between the _open() and
_create() calls is moved to a static function. Common code between the
pthread and lockless rbuff implementations was moved to shm_rbuff.c

This adds the flow down event to Ouroboros. In the shim-eth-llc, a
netlink socket is opened which listens to device up/down events. For
each event the flow is then adjusted with fccntl to notify the user
the flow is down or back up again. In the normal IPCP an event is
thrown if a write reports that the flow is down.

This revises the build system to have configuration per system
component. System settings can now be set using cmake.
The standard compliance defines were removed from configuration header
and are set in the sources where needed. Also some small code
refactors, such as moving the data for shims out of the ipcp structure
to the respective shims were performed.

This adds the basic FRCT mechanisms to the library. Upon flow alloc or
accept an FRCT instance is now created and used when reading or
writing to the flow. The timerwheel has been refactored to allow
recharging timers and removing them and is now part of the
library. The first SDU sent over the connection has the DRF set and
this initializes the connection. Sender and receiver inactivity timers
are added.

This adds a check for robust mutexes. The constant HAVE_ROBUST_MUTEX
is set accordingly in config.h. It also adds some other fixes to make
the prototype compile on the Hurd.
