* Keep BUILD_TESTING, but only run tests compatible with API (for
packaging)
* Add BUILD_TESTING_INTERNAL for all tests including internal function
tests that modify API to be run on our CI
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>.
