Configure with --enable-testtools.
BLD_ROOT is now the top build directory.
Current test requires ttynvt to be started (by root) like
# BLD_ROOT/src/ttynvt -d -E -S localhost:1234 -n ttyNVT99
Device and server name parameters must be as shown above.
Run tests like
$ make -C BLD_ROOT test # Builds the other programs too
$ make -C BLD_ROOT/test # Only running tests
$ make -C BLD_ROOT/test V=1 RUN_OPTS="--gtest_filter=Test1.t1"
