When writing to a blocking quic stream, we sometimes get duplicate
transmitted data. This occurs when a call to quic_write_blocking has to
wait for space to become available in the ring buffer. When we do a
wait, the call sets *written to the value returned in args.total_written
as filled out by the calls to block_until_pred->quic_write_again.
However, the value there is based on the amount we requested, which is
only the remaining data that we didn't append in xso_sstream_write. So
if we call quic_write_blocking with a buffer of length X, and initially
append Y bytes, and write the remainig X-Y bytes via a block_until_pred
call, then *written will return with the value X-Y, even though we wrote
the full X bytes to the ring buffer.
Fix it by recording the initial amount appended into *written, and then
add the args.total_written value if we have to wait on more space

When calling SSL_stream_reset on a QUIC stream object that has received
all data that is expected to be sent (i.e. when the sender has sent a
STREAM frame with the FIN bit set), we encounter the following segfault:
Program received signal SIGSEGV, Segmentation fault.

This occurs because:
1) When the stream FIN bit is set, the quic stack frees the underlying
stream structures immediately within the QUIC stack
and
2) when SSL_stream_reset is called, the call stack indicates we call
quic_validate_for_write, which attempts to access the
xso->stream->sstream QUIC_SSTREAM object, which was already freed in
(1)
The fix I think is pretty straightforward. On receipt of a STREAM frame
with a FIN bit set, the QUIC stack sets the QUIC_STREAM object state to
QUIC_SSTREAM_STATE_DATA_RECVD, which means we can use that state to
simply assert that the stream is valid for write, which allows it to be
reset properly.

The quic implementation defined a set of LIST_* macros for list
manipulation, which conflicts with the generally support BSD api found
in the queue.h system header. While this isn't normally a problem, A
report arrived indicating that MacOSX appears to implicitly include
queue.h from another system header which causes definition conflicts.
As the openssl macros are internal only, it seems the most sensible
thing to do is place them in a well known namespace for our library to
avoid the conflict, so add an OSSL_ prefix to all our macros

SSL_poll indicates that a stream which has had the fin bit set on it,
should generate SSL_POLL_EVENT_R events, so that applications can detect
stream completion via SSL_read_ex and SSL_get_error returning
SSL_ERROR_ZERO_RETURN.
However, the quic polling code misses on this, as a client that
completely reads a buffer after receipt has its underlying stream buffer
freed, loosing the fin status
We can however detect stream completion still, as a stream which has
been finalized, and had all its data read will be in the
QUIC_RSTREAM_STATE_DATA_READ state, iff the fin bit was set.
Fix it by checking in test_poll_event_r for that state, and generating a
SSL_POLL_EVENT_R if its found to be true, so as to stay in line with the
docs.
