This patch implements the client-side part of the remote credential guard feature
as described in MS-RDPEAR. The 2 main changes are: shipping the TSRemoteGuardaCreds in
NLA, and implement the rdpear channel that allows LSASS to remote all the calls to
our client. For now it's UNIX only as the windows implementation would be implemented
in a completely different way.
To test, you may establish you ccache and then connect with (RCG enabled on the server):
xfreerdp /remoteGuard /u:<user> /d:<domain> /v<server>
That should log you in, and in the session you should not be asked for credentials when
doing mstsc /remoteGuard /v:<other server>.
This patches adds support for octet string containers that are used by SPNego
(a subfield is contained in an octet string record).
It also adds a performance test to test reallocations in asn1 encoder.
It fixes reallocation problems for both chunks and containers.
