WTSStartRemoteControlSession doesn't allow to specify additional flags
therefore add a new extended version WTSStartRemoteControlSessionEx
with an additional "flags" parameter.
The following flags are defined:
REMOTECONTROL_FLAG_DISABLE_KEYBOARD - disable keyboard input
REMOTECONTROL_FLAG_DISABLE_MOUSE - disable mouse input
REMOTECONTROL_FLAG_DISABLE_INPUT - disable input (keyboard and mouse)
Move wtsapi tests that only make sense when run within a session
("interactive") to TestWtsApiExtra since they either brake automated
builds or don't make sense if the return value isn't checked.
TestWtsApiExtra is not build by default but can be enabled by specifying
-DTESTS_WTSAPI_EXTRA=ON (this option is only available if BUILD_TESTING
is enabled).
The tests set the ctest label WTSAPI_EXTRA and can therefore also
be run explicitly with ctest -L WTSAPI_EXTRA.
winpr is now always build as single library.
The build option MONOLITHIC_BUILD doesn't influence this behavior anymore.
The only exception is winpr-makecert-tool which is still build as extra
library.
This obsoletes complex_libraries for winpr.
