Peter Hutterer 4809a5e4b8 test/pyxtest: add test for ScreenSaverFreeAttr stale pPriv code path
Add TestScreenSaverFreeAttr which exercises the ScreenSaverFreeAttr
code path by setting attributes, activating the screen saver, then
closing the client connection (triggering resource cleanup).

While ScreenSaverFreeAttr currently does not dereference pPriv after
CheckScreenPrivate, this test verifies the code path is safe and
would catch regressions if future code changes introduced a stale
pointer dereference (same pattern as ZDI-CAN-30168).

                        X server test suite

This suite contains a set of tests to verify the behaviour of functions used
internally to the server.

= How it works =
Through some automake abuse, we link the test programs with the same static
libraries as the Xorg binary. The test suites can then call various functions
and verify their behaviour - without the need to start the server or connect
clients.

This testing only works for functions that do not rely on a particular state
of the X server. Unless the test suite replicates the expected state, which
may be difficult.

= How to run the tests =
Run "make check" in the test directory. This will compile the tests and execute
them in the order specified in the TESTS variable in test/Makefile.am.

Each set of tests related to a subsystem are available as a binary that can be
executed directly. For example, run "xkb" to perform some xkb-related tests.

== Adding a new test ==
When adding a new test, ensure that you add a short description of what the
test does and what the expected outcome is.
