079731068c [core] fix freezing connection to childSession
When connecting to child session(or a VM), we have CredSSP/Nego/ActivationSequence
instead of Nego/CredSSP/ActivationSequence. Before the patch, we were not applying
flags read in the NegoResponse to the settings and that was leading to FreeRDP
thinking that the remote server was not supporting EXTENDED_CLIENT_DATA_SUPPORTED.
That was later preventing some GCC blocks to be sent, and make the server unhappy
and freeze the connection.

061148f856 [nla] initial server-side remote credential guard support
Adds support for server-side remote credential guard in NLA. When enabled that allows
the remote user to connect without shipping credentials in TSCred packets. Instead
it will send his TGT encoded with a TGS from the remote server. This way the server
is able to populate that TGT in a local credential cache without knowing the user's
password.

The patch only treats the NLA part and does not contain the associated RDPEAR channel
that allows to have the complete interaction to retrieve new access tokens.

3c18a9980f [client,win32] implement connection to child session
Under windows you can connect to a child session by requesting a named pipe to
the local server, and then do some RDP on this named pipe.
The protocol is like for /vmconnect with CredSSP, then Nego and then the "normal"
workflow for a connection. For CredSSP we force the usage of NTLM for the Negociate
SSPI, and the credentials are empty.

7c24da917e Add RDSTLS security protocol
The client tries to connect using RDSTLS only when it has received a
server redirection PDU with LB_PASSWORD_IS_ENCRYPTED flag.

The server exposes RDSTLS on negotiation if it has been configured on settings.
Then authenticates a client using configured credentials from settings:
RedirectionGuid, Username, Domain, Password.

c7448c03fb Added FREERDP_LOCAL
CMake 2.8 does not support default visibility on windows.
To allow building tests add the FREERDP_LOCAL define for each
function that is internal to FreeRDP.
When build with testing these functions are exported and available
for use by tests.

6a8d21cab9 Fix server-side protocol negociation
Before this patch, RDP security was (wrongly) the fallback when negociating a
security protocol between the client and the server. For example when a client
was claiming TLS-only when connecting to a FreeRDP based-server with RDP security only,
the result of the negociation was that the server started to do RDP security.
The expected behaviour is to send a nego failure packet with error code
SSL_NOT_ALLOWED_BY_SERVER. This patch fixes this.

We also try to handle all cases of failed negociation and return the corresponding
error code.
