The function was returning under a cleanup handler, which is not
allowed. We don't do anything with the return value if the write
thread ends, so just stopping the thread is fine.

There was a dealloc() call in oping server under mutex, which could
leave that mutex locked when the thread was cancelled, causing oping
to hang on exit. This avoids calling dealloc under lock.

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 oping and ocbr servers were using non-blocking read/writes. This
caused writes to fail on high-performance tests if the buffer got
full, instead of waiting for a slot in the buffer. The write failure
caused the server to quit. This fixes the tools by setting the I/O to
blocking write and non-blocking read.

The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but
the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE
clock. This causes the blocking reads not to timeout correctly.
The oping was updated to detect server timeouts and finish gracefully.

This removes the dependencies for the tools on some ouroboros internal

This commit deprecates ouroboros_init and ouroboros_fini and adds them
as a constructor or destructor, causing these function to be run
automatically when a program that links to the library calls and exits
main(). For this to fully work, the library had to be split so that we
can avoid the irmd calling these functions (the IRMd has to create the
shm structures on which these calls depend).
The library is split in 3 parts: libouroboros-dev, libouroboros-irm
and libouroboros-common. The latter is linked to the other two so that
including libouroboros-dev or libouroboros-irm will also link
libouroboros-common.

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.

When hammering the oping thread, it will have write fails when the
buffer gets full as its flow is non-blocking. It would stop and
deallocate the flow, but should just continue.
