5e580eefac server: add SSL_OP_NO_RENEGOTIATION fallback path
With LibreSSL SSL_OP_NO_CLIENT_RENEGOTIATION is opaque which is not
compatible with the OpenSSL 1.0.2 and earlier code path in
red-stream.cpp while SSL_OP_NO_RENEGOTIATION is not yet defined for the
newer OpenSSL code path in reds.cpp.

So with OpenSSL 1.1.0 and later if SSL_OP_NO_RENEGOTIATION is undefined
and SSL_OP_NO_CLIENT_RENEGOTIATION is defined then define the former as
the latter. This will allow the build to succeed with LibreSSL 3.7.2 and
in the future when newer LibreSSL versions add SSL_OP_NO_RENEGOTIATION
that code path will then be used automatically.

f6f998004b Wrap spice.h in order to do some adjustment
Instead of including spice.h directly include an header that wraps
it. This allows to remove the SPICE_SERVER_INTERNAL define.
Currently is used to rename SpiceCharDeviceInstance to RedCharDevice
and reduce its visibility to hidden. This remove some warnings
and some weird code in the source.

Allows to be used by both C and C++ code.
So to leave part of the code in C and part move to C++.

cd2a317096 Add support for clients connecting with the WebSocket protocol.
We do this by auto detecting the inbound http(s) 'GET' and probing
for a well formulated WebSocket binary connection, such as used
by the spice-html5 client.  If detected, we implement a set of
cover functions that abstract the read/write/writev functions,
in a fashion similar to the SASL implementation.

This includes a limited implementation of the WebSocket protocol,
sufficient for our purposes.

9a0d8b2db8 red-stream: Propagate RedStreamSslStatus type
Do not convert RedStreamSslStatus enumeration type back to int.
This allows compilers to perform some more type safe checks.

63d02ab10e red-stream: Define interface for manual flush
The writing to network was always immediate.
Every write in the stream causes a write to the OS.
This can have some penalty if you don't write large data as network
packets can be more fragmented or you encrypt data in smaller chunks
(when data are encrypted some padding is added then data is split in
multiple of encryption block which is usually the size of encryption
key and this is done for every write).
Define an interface to allow higher levels code to tell low level when
data should be sent to remote or when can wait more data.

5c438510cd Handle SASL initialisation mainly in red-stream.c
Asynchronous code jumping from a file to another is tedious to read
also having code handling the same stuff in two files does not look
a good design.

de5b166b71 Remove common/mem.h includes
common/mem.h contains mainly memory allocation functions.
As we decided to move to Glib calls directly avoid to include
function declaration we should not use anymore.

a5aa2a2261 Use standard "Red" namespace
The objects RedsStream and RedsSASL are currently using the namespace
"Reds" rather than the standard "Red" namespace used throughout the rest
of the project. Change these to be consistent. This also means changing
method names and some related enumeration types.

The files were also renamed to reflect the change:
  reds-stream.[ch] -> red-stream.[ch]
