* server/tests/test_display_base.c: Add explicit casts

Now, cursor is being shown in all tests as a white rectangle and is
running in the screen doing a diagonal movement. It's a very simple
way to test cursor commands and is sufficient for our tests.
As suggested by Alon, a simple automated test to try to find
regressions in Spice code.
To use this, compile Spice with --enable-automated-tests and
run test_display_streaming passing --automated-tests as parameter.
Several functions in server/ were not specifying an argument list,
ie they were declared as void foo(); When compiling with
-Wstrict-prototypes, this leads to:
test_playback.c:93:5: erreur: function declaration isn’t a prototype
[-Werror=strict-prototypes]
create_test_primary_surface::test_display_base.c creates a
QXLDevSurfaceCreate structure and initialize it, but doesn't set
the position field. Moreover, this structure has 4 bytes of padding
to the end (as shown by pahole from dwarves), so initialize the whole
structure to 0 before using it.
When compiling spice with make CFLAGS="-g3 -ggdb3 -O0 -Wall -Werror",
the build broken because of a few unused variables/missing returns.
This patch fixes these warnings.
