This removes all of the SIGIO handling support used for input
throughout the X server, preparing the way for using threads for input
handling instead.
Places calling OsBlockSIGIO and OsReleaseSIGIO are marked with calls
to stub functions input_lock/input_unlock so that we don't lose this
information.
xfree86 SIGIO support is reworked to use internal versions of
OsBlockSIGIO and OsReleaseSIGIO.
v2: Don't change locking order (Peter Hutterer)
v3: Comment weird && FALSE in xf86Helper.c
Leave errno save/restore in xf86ReadInput
Squash with stub adding patch (Peter Hutterer)
v4: Leave UseSIGIO config parameter so that
existing config files don't break (Peter Hutterer)
v5: Split a couple of independent patch bits out
of kinput.c (Peter Hutterer)

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.
