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.

8b9c40248a Increase TCP_USER_TIMEOUT to avoid disconnections. 
TCP_USER_TIMEOUT value is too small, it is only 4 seconds. 
That causes random disconnections reported in the bug report https://github.com/FreeRDP/FreeRDP/issues/2802
This patch should fix the bug report https://github.com/FreeRDP/FreeRDP/issues/2802

428cbd802d Fixes #2982. The idea is to be able to create the socket externally and pass that socket FD to FreeRDP so that it can be used there. 
The idea suggested is to use the following interface:

settings->ServerHostname = "|"
settings->ServerPort = SocketFD

68e8569110 winpr/synch: remove the dependency on winsock.h 
winsock.h pulls in a lot of defines and dependencies that are not
required and partially unwanted in winpr's core (for parts that are not
related to network). In order to get rid of this dependency and have an
independent defines for extended winpr functions the WINPR_FD_* defines
are used internally (and for exposed functions). Where required, like in
WSAEventSelect, the FD_* is mapped to WINPR_FD_*.

75407edf37 Fix event created for WSAEventSelect: The event we pass to WSAEventSelect should be WSAEVENT instead of normal event. 
From MSDN, it looks same as CreateEvent(NULL, FALSE, FALSE, NULL):
	The WSACreateEvent function creates a manual-reset event object with an initial state of nonsignaled. The event object is unnamed.
However they are not really equivalent. When we use normal event, the WSAEventSelect still works but the event appears to be 'auto-reset'.

388d014888 core/tcp: set TCP_USER_TIMEOUT if available 
Keepalive settings are usually (depending on the implementation) only
used if the TCP connection is idle.
If the network is interrupted/disconnected/... click or keyboard input
generates outgoing traffic therefore the connection isn't idle
anymore and keepalives might not be used causing the connection to
stay open and the client to stall.

Linux 2.6.36 added a TCP_USER_TIMEOUT TCP socket option that lets a
program specify the maximum time transmitted data may remain
unacknowledged before TCP will close the corresponding connection with
ETIMEDOUT.

Setting TCP_USER_TIMEOUT allows us to detect a network problem (like
cable disconnect) even if the connection isn't idle.

dd6d829550 Allow transport_write calls to be non-blocking 
This big patch allows to have non-blocking writes. To achieve
this, it slightly changes the way transport is handled. The misc transport
layers are handled with OpenSSL BIOs. In the chain we insert a
bufferedBIO that will bufferize write calls that couldn't be honored.

For an access with Tls security the BIO chain would look like this:
  FreeRdp Code ===> SSL bio ===> buffered BIO ===> socket BIO

The buffered BIO will store bytes that couldn't be send because of
blocking write calls.

This patch also rework TSG so that it would look like this in the
case of SSL security with TSG:
                                         (TSG in)
                              > SSL BIO => buffered BIO ==> socket BIO
                             /
FreeRdp => SSL BIO => TSG BIO
                             \
                              > SSL BIO => buffered BIO ==> socket BIO
                                        (TSG out)

So from the FreeRDP point of view sending something is only BIO_writing
on the frontBio (last BIO on the left).
