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 moves Resource Information Base (RIB) initialization into the
ipcp_init() function, so all IPCPs initialize a RIB. The RIB not shows
some common IPCP information, such as the IPCP name, IPCP state and
the layer name if the IPCP is part of a layer.
The initialization of the hash algorithm and layer name was moved out
of the common ipcp source because IPCPs may only know this information
after enrollment. Some IPCPs were not even storing this information.

The new GCC 11.1 compiler discovered s_dist would be uninitialized
with an unknown policy, so it doesn't need to be free'd. Also removes
some unneeded includes in broadcast dt.c that I had pending.

The connection manager and enrolment components of the unicast and
broadcast IPCP have a lot in common, as conjectured in the paper. The
initial implementation of the broadcast IPCP just duplicated the
code. This moves the shared functionality to common ground.

GCC 10 defaults to -fno-common, so some variables that were defined in
the headers needed to be declared "extern". The GCC 10 static analyzer
can now be invoked using the DebugAnalyzer build option.

This is more in line with the write() system call and prepares for
partial writes. Partial writes are disabled by default (and not yet
implemented).

The initial implementation for the ECDHE key exchange was doing the
key exchange after a flow was established. The public keys are now
sent allowg on the flow allocation messages, so that an encrypted
tunnel can be created within 1 RTT. The flow allocation steps had to
be extended to pass the opaque data ('piggybacking').

The API calls for the IPCP to inform the IRMd of IPCP creation and
incoming flow request had the pid_t in the call. This pid_t is removed
and the getpid() call is now placed inside the function. Also
refactors the cleanup for the main() functions of some of the lower
IPCPs.

This adds a new flow_join operaiton for broadcast, which is a much
safer solution than overloading destination name semantics. The
internal API now also has a different IPCP_FLOW_JOIN operation. The
IRMd doesn't need to query broadcasts IPCPs for the name, it can just
check if an IPCP with the layer name exists. The broadcast IPCP
doesn't need to implement the query proxy call anymore.

This adds a broadcast IPCP that allows us to easily create multicast
applications. The broadcast IPCP accepts flows for "<layer_name>.mc".
A tool, obc (Ouroboros broadcast), is added that sends and reads a
message to a broadcast layer.
