PROTOCOL_RDP is equals 0 so if we and it with anything is still 0.
Correct way of doing it is to compare two values.

In commit 0e1a073384 there was a mistake -
originally code said different then kerberos. Because of that NLA authentication
of server side didn't work for me.

ff8b2c1b0e core: Fix IPv6 handling on Windows
On Windows the sockaddr struct is smaller than sockaddr_in6.
This causes getsockname to fail because the buffer is too small.
The new code uses sockaddr_storage which should be large enough to
hold any supported protocol address structure.

See: http://pubs.opengroup.org/onlinepubs/009696699/basedefs/sys/socket.h.html

e7ae3f6bab fix nla: don't use server version
FreeRDP currently only supports CredSSP protocol version 3. However the
current implementation always sent back the version received by the
server indicating that this version was supported.
With recent windows updates applied the protocol changed and this approach
doesn't work anymore (see
https://msdn.microsoft.com/en-us/library/mt752485.aspx for protocol changes).

With this fix FreeRDP always sends version 3 as supported version.

Credit goes to @mfleisz.

9bfe2fcfb9 cmake: rework logic to apply -msse2, -msse3, -mssse3 to specific files
If we apply -mssse3 to files that don't need it, gcc may automagically
generate instructions that will not run on certain CPUs. This breaks the
runtime feature detection code (IsProcessorFeaturePresent).

Provide support for older versions of libavcodec
My method was to find the LIBAVUTIL_VERSION_* at the commit where the
updated AV_ prefixed constants became available, add one "micro" version
to it, then if it's not at least that version, provide the unprefixed
constant. It just so happens that the same commit introduced all
the AV_* constants.

Fix future ffmpeg support
The AV_ prefixed constants have been available since
ffmpeg@def97856de6021965db86c25a732d78689bd6bb0 (2015-07-07), or version
2.8.

The non-prefixed constants are set to be removed in the next ffmpeg
release, and were removed in
ffmpeg@302554835e39b79b977ed60c9afe81b44590dfef (2016-12-05).

191b8f950f Fix for #4330
Since ec027bf dynamic resolution is broken when used with egfx. Before that commit
we were tracking a server sent resize by setting a DesktopResize callback. This callback
is called when the desktop is resized by the server. Anyway the problem was that when this
callback is called, the activation sequence is not always completed, which were leading to
some freeze with 2012r2 servers (sending packets before the sequence is finished).
So with the faulty commit, we are tracking server resizes by subscribing to the Actived
event, that is called at the end of a reactivation sequence, so we're sure to not send packets
when not fully activated.
Anyway the issue that shows on (#4330) is that when you use egfx, no reactivation sequence happens,
the server only sends a ResetGraphics message with the new size, and so we miss the resized event.
This fix introduces a new GraphicsReset event, makes the display channel subscribe to that event,
and react accordingly.

cf899eb5ba Fix #4299: gdi_CRgnToRect
The coordinates from RDP ROP commands do not (always) have
0,0 as the origin of the drawing operation.
Adjust the coordinates to our local coordinate system.

2a6c9e1b87 Add an activated event and a Timer event
Added an event that is triggered when the activation sequence is finished.
We also define a timer event that is neat to have for regular operation.

9f5d0d4c4d crypto: Improve PER OID calculations
"(oid[0] << 4) & (oid[1] & 0x0F)" statement is always 0. It is not
problem currently because the only OID which is written by this
function should have 0 there. The function to read/write are pretty
limited anyway and can't work properly with all kind of OIDs. Maybe
it would be better to hardcode the OID there without decoding
and encoding. But those functions are already there so let's improve
them a bit according the spec and warn about limited set of
supported OIDs.
